FIELD OF INVENTION

[0002] The present invention relates generally to cosmetic compositions incorporating Serissa japonica extracts and their use to reduce fine lines and wrinkles, improve skin tone and lighten discolorations of the skin and to improve the overall appearance of skin by increasing epidermal thickness, reducing melanin production, and stimulating the production of collagen and/or halyuronic acid.

BACKGROUND OF THE INVENTION

[0003] Consumers are increasingly interested in cosmetics that treat, mitigate, or delay the signs of aging or aged skin. The signs of aging or aged skin manifest themselves in lines and wrinkles, sagging, dullness, discoloration, uneven tone, and/or rough texture. Further, aged skin lacks strength and elasticity and is therefore fragile. The cosmetics industry is actively pursuing products that may be used to reduce signs of aging or aged skin (anti-aging compounds) and thereby provide anti-wrinkle, rejuvenating, and skin lightening benefits. [0004] Human skin is broadly divided into two layers: the surface epidermis which provides an anatomical barrier to foreign elements and maintains the body's internal environment, and the underlying dermis which provides nutritional and structural support to the epidermis. The epidermis mainly consists of keratinocytes and is comprised of several sub-layers (from the innermost outwards): Stratum germinativum/Stratum basale, Stratum spinosum, Stratum granulosum, and Stratum corneum. The keratinocytes, generated by the mitosis of keratinocyte stem cells, originate in the stratum basale and then push up through the strata. As these cells move to the surface of the skin they undergo gradual differentiation, becoming anucleated, flattened, and highly keratinized. During this process the keratinocytes become highly organized. They form desmosomes, cellular junctions, between each other and, through the excretion of keratin proteins and lipids, form an extracellular matrix which strengthens the skin. Eventually the keratinocytes die off and form the stratum corneum. In healthy skin, keratinocytes are shed and replaced continuously every 30 days.

[0005] While the keratinocytes are within the stratum basale they acquire melanin, a black ultraviolet light absorbing pigment, from melanocytes. Melanocytes produce melanin within organelles known as melanosomes and then transfer the melanin containing melanosomes to neighboring keratinocytes via their dendrites. Within each keratinocyte the melanosomes form a melanin cap which is retained within the keratinocyte until the keratinocyte is shed from the skin. The melanin cap reduces ultra-violet-induced DNA damage to the human epidermis and the underlying cells and tissues. Melanin provides the skin with its color and thus the intensity of skin color is directly related to the number, size, melanin content, rate at which melanin containing melanosomes are formed, rate at which the melanin containing melanosomes are transferred to keratinocytes, and rate at which melanin degrades within keratinocytes. For a more detailed background on melanin, see G. Costin and V. Hearing, "Human skin pigmentation: melanocytes modulate skin color in response to stress," The FASEB Journal Vol. 21 , pages 976-994, April 2007, the disclosure of which is incorporated herein by reference in its entirety.

[0006] Hyaluronic acid (HA), a gel-like aminoglycan, also plays an important role in normal epidermis. HA is an integral part of the extracellular matrix of basal keratinocytes, maintaining the extracellular space and providing an open as well as hydrated structure for the passage of nutrients. HA also acts as a free-radical scavenger, contributing to epidermal's protection against solar radiation. HA may also act as a modulator of keratinocyte proliferation and migration.

[0007] The dermis is the underlying layer of the skin located between the epidermis and subcutaneous tissue. Since the epidermis lacks blood vessels, the cells of the epidermis rely upon the blood vessels in the dermis for their nutrients and oxygen. The dermal-epidermal junction (DEJ) is a specialized structure that maintains close contact between the lamina densa, a layer of extracellular matrix upon which the epithelium sits, and the underlying connective tissue of the dermis. The DEJ is comprised mainly of collagen and elastin and structured as interlocking finger- like projections from the epidermal and dermal layers called Rete ridges. The Rete ridges increase the surface area of the epidermis exposed to the dermis at the DEJ, so that the transfer of necessary nutrients/oxygen is more efficient, and the two layers of the skin form a strong bond that resists mechanical stress (shear). Additionally, the dermis is the thickest of the skin layers and comprises the extracellular matrix of the skin, which is maintained by fibroblast cells. Fibroblasts maintain the structural integrity of connective tissues by continuously secreting precursors of the extracellular matrix. The main structural component of the dermis is a protein called collagen. Bundles of collagen molecules pack together throughout the dermis, accounting for three-fourths of the dry weight of skin. Collagen has great tensile strength; along with soft keratin, it is responsible for skin strength and elasticity. For a more detailed background on collagen, see Lodish, et al. Molecular Cell Biology, W.H. FREEMAN, New York, NY 4th edition, 2000, the disclosures of which is incorporated herein by reference in their entirety.

[0008] Histological studies of the skin show that as aging occurs, the skin undergoes structural, functional, and metabolic changes that parallel the aging and degenerative changes in other body organs. While chronological and/or hormonal aging play a significant role in skin aging, environmental stresses such as sun exposure may initiate and/or accelerate the aging of the skin due to, in part, oxidative damage from overexposure to ultraviolet (UV) sunlight. In aged and/or aging skin the cells may take longer to replenish, be less numerous, and/or breakdown more quickly. In particular, as aging occurs, the production of collagen is reduced while the degradation is accelerated due to an overproduction of collagenase, i.e. a protease that breaks down collagen. The resulting collagen deficiency may lead to reduction in skin strength and elasticity. Further, given that collagen is a major component of the DEJ, the DEJ flattens out with aging, such that the skin is more fragile and more likely to shear. As the DEJ flattens the amount of nutrients/oxygen transferred to the epidermis through the DEJ is reduced because the surface area in contact with the epidermis shrinks. The reduction of HA within the epidermal extracellular matrix reduces the epidermis's ability to transfer the available nutrients/oxygen to its cells. This inefficient nutrient/oxygen transport impacts the keratinocytes and mealnocytes of the epidermis. The keratinocytes renewal rate is reduced and as a consequence the stratum corneum loses its capacity to retain moisture and the skin dehydrates. Moreover, the melanocytes become less numerous and the remaining melanocytes may produce a greater amount of melanin leading to discoloration/hyperpigmentation of the skin and/or solar lentigenes, "age spots." At the surface of the skin, aged or aging skin may exhibit lines and wrinkles, sagging, dullness, discoloration, uneven tone, rough texture, and the like. Additionally, aged or aging skin exhibits less strength and flexibility and is more fragile. These signs of aging may be exacerbated by common medications such as those prescribed for the treatment of Parkinson's disease, i.e. Levodopa, or menopause, i.e. hormone therapies.

[0009] One well known product used for anti-aging skin care is retinol which has proven to be effective in diminishing the visual signs of aging on facial skin. Retinol has negative effects including the tendency to cause skin irritation or the tendency to breakdown when exposed to oxygen or UV thereby impairing its effectiveness.

[00010] Serissa japonica, also known as the tree of a thousand stars, is an evergreen shrub with small, bright green, oval leaves that is native to open subtropical woodlands and wet meadows in southeast Asia. Depending on the variety, small white or pink flowers cover the tree in late spring. The natural color of the trunk is gray and the bark roughens with age.

[0001 1 ] There remains a need for cosmetic compositions which address the signs of aging, in particular the appearance of wrinkles, lines, and discolored areas. It is therefore an object of the present invention to provide new compositions and methods for treating, ameliorating, and/or preventing signs of aged or aging skin. It is a further object of the invention to improve the overall appearance of aging or aged skin.

[00012] The foregoing discussion is presented solely to provide a better understanding of the nature of the problems confronting the art and should not be construed in any way as an admission as to prior art nor should the citation of any reference herein be construed as an admission that such reference constitutes "prior art" to the instant application.

SUMMARY OF THE INVENTION

[00012] In accordance with the foregoing objectives and others, it has been found that extracts of Serissa japonica are surprisingly potent regulators of collagen, hyaluronic acid, and melanin synthesis within the body and thus are beneficial agents against signs of aging and discoloration within the skin.

In other embodiments of the current invention the improvement of the skin may be due to an increase in collagen synthesis, an increase in hyaluronic acid synthesis, an increase epidermal thickness, a reduction in melanin synthesis; or any combination thereof.

[00017] In yet another embodiment of the invention, the extract may be present in an amount about 0.0001 wt% to about 90 wt% based on the total weight of the composition, and in a further embodiment may be present in an amount of from about 0.01 wt% to about 10 wt% of the total weight of the composition. In certain embodiments, the Serissa Japonica plant extract may be derived from the leaves and stems of the Serissa Japonica plant. [00018] Another embodiment of the current invention is directed to a method of improving the barrier function and viability of the skin by topically applying to the skin the above-noted composition in an amount effective to increase collagen synthesis, to increase hyaluronic acid synthesis, increase epidermal thickness, reduce melanin synthesis, or any combination thereof. In a certain embodiment of this method the extract is derived from leaves and stems of Serissa Japonica. In further embodiments of the method, the plant extract is present in an amount of about 0.0001 wt% to about 90 wt% based on the total weight of the composition, and in still further embodiments, the plant extract is present in an amount of about 0.01 wt% to about 10 wt% based on the total weight of the composition.

[00019] A further embodiment of the current method is directed to treating wrinkles, fine lines, or a sagging skin, by topically applying to the skin the above- noted composition in an amount effective to treat the skin in need thereof.

[00020] A method for lightening skin in need thereof is another embodiment of the current invention. The method involves topically applying to skin in need of lightening the above-noted composition in an amount effective to achieve a lightening benefit. In additional embodiments of this method the plant extract is present in an amount of about 0.01 wt% to about 10 wt% based on the total weight of the composition.

[00021 ] In certain embodiments the lightening benefit may be selected from the group consisting of: (a) bleaching hyper-pigmented hair, skin, lips and/or nails; (b) reducing age spots; (c) evening or optimizing skin discoloration; (d) improving the appearance of dark circles under the eyes; (e) treating melasma, cholasma, freckles, after-burn scars, and post-injury hyper-pigmentation; (f) bleaching hair on the scalp, legs, face, and other areas where bleaching and color reduction are desired; (g) bleaching nail stains; and (h) combinations thereof. The lightening benefit may be due to a reduction in melanin synthesis, and in certain embodiments the reduction of melanin synthesis may be about 20-100%.

[00022] A further embodiment of the current invention is directed to a method of treating skin comprising topically applying to an area of the skin in need thereof an effective amount of a Serrisa japonica extract that modulates a skin biomarker, wherein the ability of the Serrisa japonica extract to modulate a skin biomarker has been determined by an assay which measures the amount of change in a skin biomarker selected from the group comprising epidermal thickening; total collagen; pro-collagen; and hyaluronic acid binding protein in skin cells and/or skin cell pre- differentiation precursors that have been contacted with the Serrisa japonica extract.

[00023] These and other aspects of the present invention will be better understood by reference to the following detailed description and accompanying figures.

[00056] DEFINITIONS

[00057] All terms used herein are intended to have their ordinary meaning unless otherwise provided.

[00058] The term "active amount" refers to the amount of Serissa japonica extract absent diluent, solvent, carrier, filler or any other ingredient. An "amount effective" or an "effective amount" to provide a particular anti-aging benefit to the skin refers to the "active amount" of extract required to provide a clinically measurable improvement in the particular manifestation of aging, i.e., an unwanted feature associated with aging, when applied or administered for a time sufficient to provide a clinically measurable improvement in the particular manifestation of aging.

[00059] As used herein, the term "a person in need thereof" refers to an individual with a normal but noticeable and undesired skin condition, unwanted feature, due to aging, e.g. lines and wrinkles, sagging, dullness, discoloration, uneven tone, rough texture, etc., or an individual that elects to decrease the effects of aging in the absence of a noticeable and undesired skin condition, i.e. as a preventative or prophylactic.

[00060] As used herein, the term "consisting essentially of is intended to limit the invention to the specified materials or steps and those that do not materially affect the basic and novel characteristics of the claimed invention, as understood from a reading of this specification.

[00061 ] By "cosmetically acceptable" it is meant that a particular component is generally regarded as safe and nontoxic at the levels employed.

[00062] As used herein, the term "discoloration" includes discrete pigmentation and mottled pigmentation. Discrete pigmentation are distinct uniform areas of darker pigment and may appear as brown spots or freckles on the skin and may include solar lentigo, darkened spots on the skin caused by aging and the sun also known as "liver spots," "senile freckles," or "age spots," or ephelis, freckles. Mottled pigmentation are dark blotches that are larger and more irregular in size and shape than discrete pigmentation and may include conditions such as chloasma, melasma, skin discolorations caused by hormones, i.e. as the result of pregnancy, birth control pills, or estrogen replacement therapy. The discoloration may be the result of external factors including, but not limited to, UV-R, tanning and photoaging, drugs, and/or chemicals, or internal factors including, but not limited to, genetics, hormonal influences, and/or inflammation.

[00063] Elasticity of the skin refers to the springiness and resilience of skin's ability to regain its original shape and size after deformation. Elasticity of the skin may be evaluated by a pinch test that can either cause deformation by stretching or squeezing the skin.

[00064] As used herein, the term "essential oil" refers to the volatile ethereal fraction obtained from a plant or plant part by a physical separation process such as distillation or chromatographic separation. The essential oils are typically terpenoids often comprising monoterpenes and have the odor and flavor of the plant from which they were extracted.

[00065] The term "lightening" is meant herein to refer to any detectable reduction in skin color/pigmentation , of hair, skin, lips, and/or nails, e.g., a reduction visible to the naked eye, that occurs after contacting the skin of an individual with a treatment regimen comprising a Serissa japonica extract. As an example, this may refer to a evening or optimization of a discoloration of the skin, i.e. bleaching age spots, freckles, efc.to reduce or eliminate the color difference between the discoloration and the surrounding skin; and/or an overall lightening of the individual's normal pigmentation/skin color, i.e. skin lightening. The terms reducing pigmentation, lightening, bleaching, or color reduction are used interchangeably herein. Without wishing to be bound to a particular theory, applicants believe that the current herbal extracts achieve this lightening effect by impairing the synthesis of melanin thereby reducing melanin production. The term "reducing melanin production" is used herein to mean a detectable lowering of the amount of melanin synthesized by melanocytes exposed to a Serissa japonica extract as compared to the amount of melanin synthesized in the absence of such an inhibiting compound. The term "reduction" as used herein in relation to melanin means the complete prevention, control of secretion, or a degree of reduction of the formation of melanin, respectively. The term "lowering" in one embodiment refers to about a 10% to about a 100% decrease in the amount of melanin thereby synthesized. More in one embodiment, the term "lowering" refers to about a 25% to about a 100% decrease in the amount of melanin synthesized. Still more in one embodiment, the term "lowering" refers to about a 35% to about 100% decrease in the amount of melanin synthesized. The terms lowering, reducing, decreasing, suppressing and inhibiting, when used in relation to melanin production, are intended to be used interchangeably. Such reduction in melanin production may be evaluated subjectively or by using assays including, but not limited to, in vitro, ex vivo, animal models, and/or clinical models known to those skilled in the art. For example, the reduction of melanin synthesis may be established using methods known to those skilled in the art including, but not limited to, human melanocyte cultures, mouse melanoma cultures, see Example 3 below and U.S. Patent 7,189,419 hereby incorporated by reference in its entirety for all purposes, HRM2 hairless mouse model, see Chung, et al., "Evaluation of in vitro and in vivo anti-melanogenic activity of a newly synthesized strong tyrosinase inhibitor (E)-3-(2,4 dihydroxybenzylidene)pyrrolidine-2,5-dione (3-DBP)," Biochim Biophys Acta. 2012 Jul;1820(7):962-9 hereby incorporated by reference in its entirety for all purposes, Zebra fish models, See Choi, T.Y.; Kim, J.H.; Ko, D.H.; Kim, C.H.; Hwang, J.S.; Ahn, S.; Kim, S.Y.; Kim, CD.; Lee, J.H.; Yoon, T.J.

[00066] "Prevention" as used herein, as well as related terms such as "prevent" or "preventing," refer to affording skin not yet affected by the condition a benefit that serves to avoid, delay, forestall, minimize, or reduce the recurrence/ onset of one or more unwanted features associated with the skin condition to be prevented. Such preventative benefits include, for example, delaying development and/or recurrence of the condition, or reducing the duration, severity, or intensity of one or more unwanted features associated with the condition if it eventually develops. Use of the term "prevention" is not meant to imply that all subjects in a subject population administered the cosmetic composition will never be affected by or develop the cosmetic or dermatologic conditions, damage, effect, or symptom, but rather that the subject population will exhibit a reduction in the cosmetic or dermatologic damages, effects, or symptoms. For example, many flu vaccines are not 100% effective at preventing flu in those administered the vaccine. Preventing aging refers to affording not yet affected skin a benefit that serves to avoid, delay, forestall, or minimize one or more unwanted features associated with aging, such as reducing the extent of lines and wrinkles, sagging, dullness, discoloration, uneven tone, rough texture, and/or fragileness that eventually develops at the treated area.

[00067] The term "skin" as used herein includes the skin on or in the face, mouth, neck, chest, back, arms, hands, legs, and scalp. "Thin skin" is intended to include skin that is thinned due to chronological aging, menopause, or photo- damage.

[00068] "Treatment" as used herein, as well as related terms such as "treat" or "treating," refers to eradicating, reducing, ameliorating, or reversing one or more of the unwanted features associated with the skin condition being treated, such that the consumer perceives an improvement in the appearance of the skin or other treatment benefit with respect to the condition. Treating skin aging or damage refers to eradicating, reducing, ameliorating, or reversing one or more of the unwanted features associated with aging. Unwanted features associated with aging skin, e.g., lines and wrinkles, sagging, dullness, uneven tone, rough texture, discoloration, etc. Unwanted features associated with discoloration, e.g., age spots, freckles, melasma, chloasma, post-inflammatory hyperpigmentation, etc. Treatment benefits include, e.g., reducing the appearance of lines, wrinkles, and/or sagging, restoring lustre to the skin, evening the tone of skin, softening the skin texture, and/or lightening discolorations. The present compositions and methods are suitable for use in treating dermatological conditions of the skin in numerous areas of the body, including, without limitation the face, forehead, lips neck, arms hands, legs, knees, feet chest, back, groin, buttocks, and the like. In a in one embodiment, the compositions are applied to the face.

[00069] The term "wrinkle" or "wrinkling" refers to both fine wrinkling and coarse wrinkling. Fine wrinkling or fine lines refers to superficial lines and wrinkles on the skin surface. Coarse wrinkling refers to deep furrows, particularly deep lines/wrinkles on the face and around the eyes, including expression lines such as frown lines and wrinkles, forehead lines and wrinkles, crow's feet lines and wrinkles, nasolabial fold and marionette lines and wrinkles. Forehead lines and wrinkles refer to superficial lines and/or deep furrows on skin of the forehead. Crow's feet lines and wrinkles refer to superficial lines and/or deep furrows on skin around the eye area. Marionette lines and wrinkles refer to superficial lines and/or deep furrows on skin around the mouth. Wrinkles can be assessed for number, length, and depth of the lines.

[00070] All percentages are by weight based on the total weight of the composition, unless otherwise indicated.

[00071 ] Cosmetic Compositions

[00072] The cosmetic compositions used in the method of the current invention comprise a botanical component derived from the Serissa japonica plant. Serissa japonica plant may be in any form including, but not limited to, the whole plant, a dried plant, a ground plant or parts thereof, including but not limited to, seeds, needles, leaves, roots, bark, cones, stems, rhizomes, callus cells, protoplasts, organs and organ systems, and meristems, an extract, a dried extract, a synthetic extract, or components and/or constituents found in, or isolated from, the plant, and/or portions of the plant, or extracts derived either directly or synthetically from the plant, or any combinations thereof. For the cosmetic compositions used in this invention the botanical component is in one embodiment derived directly from the Serissa japonica plants. The botanical component may be in a pure form, a semi- pure form, or unpurified form. The Serissa japonica botanical component may be in the form of a liquid, a semi-solid, or a solid consistency. In one embodiment, the botanical component may be an essential oil.

[00073] In one embodiment, the raw materials are collected from the leaves and stems of theSerissa japonica plants. In certain embodiments, the raw materials collected from the Serissa japonica plants are ground to small particle sizes. In addition, the raw materials may be dried to reduce water content. The raw materials may be air-dried, oven-dried, rotary evaporated under vacuum, lyophilized, or dried by any other suitable method known in the art.

[00074] The extract of Serissa japonica may be obtained by distilling the raw materials with a stripping agent. The stripping agent may be a liquid that is miscible, immiscible, or partially miscible with the desired extract from Serissa japonica. Suitable stripping agents include, but are not limited to the following: water; alcohols (such as methanol, ethanol, propanol, butanol and the like); glycols; ethers (such as diethyl ether, dipropyl ether, and the like); esters (such as butyl acetate, ethyl acetate, and the like); ketones (such as acetone, ethyl methyl ketone, and the like); dimethyl sulfoxide; acetonitrile; other organic solvents; and combinations thereof. In one embodiment, the stripping agent is immiscible with the desired extract from Serissa japonica. The Serissa japonica extract may be collected by phase separation from the stripping agent. It is believed that the stripping agent increases the overall vapor pressure of a distillation system for obtaining an extract of Serissa japonica and thereby reduces the boiling point of the desired product, the Serissa japonica extract.

[00075] In other embodiments, Serissa japonica botanical component may be in the form of an extract obtained by solvent extraction, in one embodiment obtained by an organic solvent extraction. Briefly, the organic solvent extraction method involves washing and extracting the raw materials, which may be whole or ground into small particle sizes, using an organic solvent. Non-limiting examples of organic solvents include methanol, ethanol, isopropanol, dichloromethane, chloroform, hexane, xylene, and petroleum ether. An extracting machine may be used for organic solvent extraction as is well known in the field. The raw materials are pushed slowly into the extracting machine by a thruster. Organic solvent (e.g., ethanol) may be added into the machine through a solvent inlet at the top of a waste discharge outlet. Due to the difference in gravity and equilibrium, the solvent flows toward the raw material inlet, soaks the materials and flows out from the opposite side of the solvent inlet. Since the plant materials and the solvent move in opposite directions against each other, the plant materials are constantly immersed in a solution that contains a low-concentration of extract. As a result of equilibrium, high yield of plant constituent(s) may be achieved by continuously extracting the plant material against the low-concentration solution.

[00076] An extraction time suitable to extract the Serissa japonica plant constituents is used, typically between about 1 -10 hours, more in one embodiment between about 2-8 hours, and most in one embodiment between about 3-6 hours. The temperature of extraction is between about 30°C-100°C, in one embodiment between about 40°C-70°C, and more in one embodiment between about 50°C-60°C. The collected extract is then fine-filtered to remove debris, and may be used directly, or is concentrated, for example by distilling the solvent or by other conventional processing. The solution of extract actives may be rotary evaporated under vacuum or lyophilized. A typical extract's actives content is above about 25%, in one embodiment above 50%, and the extract can also be provided as an essential oil or a concentrate having a semi-solid or solid consistency.

[00077] Similarly, aqueous-organic solvent extraction involves initially collecting raw materials from the Serissa japonica plants, which may be whole or ground into small particle sizes. The ground plant material is soaked in aqueous solution that is acidic or alkaline, depending on the solubility and stability of the desired extract under acidic or alkaline (basic) conditions. For extraction under acidic conditions, an acid such as hydrochloric acid or sulfuric acid is added to water, e.g., at a concentration of about 3% (w/v). For extraction under alkaline conditions, an alkali such as sodium hydroxide or sodium carbonate is added to water. The extraction time and temperature of extraction are typically similar to that used in the organic solvent extraction method described above.

[00078] The extract is then collected and fine-filtered to remove debris. Alkaline agents (e.g., ammonia) or acidifying agents (e.g., sulfuric acid) may be added to the extract to neutralize the solution by adjusting the pH, depending on the acidity or alkalinity of the collected extract. The aqueous extract may be used directly, in concentrated or dried form. Alternatively, an organic solvent may then be added to the neutralized solution to transfer the extract from an aqueous phase to an organic phase. Examples of such organic solvents include, but are not limited to, ethanol, isopropanol, butanol, pentanol, hexanol, and xylene. The extract comprising the transferred extract actives dissolved in organic solvent may be used directly as an essential oil or a concentrate, or dried by a number of different means, such as, for example, air-drying, oven-drying, rotary evaporating under vacuum or lyophilizing to a semi-solid or solid consistency.

[00079] It should also be noted that different plants containing different constituents can be mixed and extracted together with Serissa japonica. This process of mixed extraction can in one embodiment be used for extracting those plants containing constituents with similar solubility as Serissa japonica in the solvent used for extraction, such as ethanol. The mixture of extracts can be concentrated and stored in an appropriate solvent.

[00080] In another embodiment, the Serissa japonica extract as used herein, also includes "synthetic" extracts, i.e., various combinations of known Serissa japonica plant components and/or constituents that are combined to substantially mimic the composition and/or activity of a Serissa japonica plant extract of natural origin. In one embodiment, the synthetic extracts have substantially the same number of active components as a natural Serissa japonica plant material. The correspondence of the numerical incidence of actives between the synthetic extracts and the natural Serissa japonica plant material may also be described in terms of "percent commonality." The synthetic extract has about 50 percent or more commonality to the chemical composition of a plant or natural extract. In other words, the synthetic extract has about 50 percent or more of the active ingredients found in the plant or a natural extract. More in one embodiment, the chemical composition of the synthetic extract has about 70 percent or more commonality to the chemical composition of a plant or a natural extract. Optimally, a synthetic extract has about 90 percent or more commonality to the chemical composition of a plant or a natural extract.

[00081 ] The compositions according to the invention can be formulated in a variety of forms for topical application and will comprise from about 0.0001 % to about 90% by weight of an extract of Serissa japonica, and in one embodiment will comprise from about 0.0005% to about 25% by weight, and more in one embodiment from about 0.001 % to about 10% by weight. Within the more in one embodiment range, the composition may comprise a Serissa japonica extract within a range from about 0.005%, 0.01 %, 0.05%, 0.1 %, 0.25%, 0.5%, 0.75% or 1 % up to 5%, 7.5% or 10% by weight of the total composition. The compositions will comprise an effective amount of an extract of Serissa japonica, by which is meant an amount sufficient to reduce and/or inhibit the appearance of signs of aging or damage in a given area of skin when topically applied thereto. The above amounts refer to an "active amount" of a Serissa japonica extract.

[00082] In accordance with the invention, compositions comprising components from the Serissa japonica plant include, but are not limited to, topically applied formulations, anti-oxidants, anti-inflammatories, sunscreens, cosmetics (including makeup), personal care products (e.g., antiperspirants or deodorants for controlling body odor), topicals, skin penetration enhancers, and the like. Also in accordance with this invention, the Serissa japonica plant components and additional ingredients comprising such compositions may be formulated in a variety of product forms. The compositions may be prepared in targeted delivery systems, e.g. creams, lotions, gels, toners, serums, transdermal patches, and the like, particularly for topical administration. Targeted delivery and/or penetration enhancement may also be achieved by iontophoresis.

[00083] The present invention further provides the compositions comprising the Serissa japonica plant components for the current method be in one embodiment topically administered for targeted delivery. The method of the current invention is suitable for all skin types, such as sensitive, normal, oily, or combination. In particular embodiments, the compositions may be in one embodiment applied to sensitive skin or hair types. The compositions are applied to the skin or hair for a period of time sufficient to improve the aesthetic appearance of conditions related to skin, including unwanted features associated with aging, e.g., lines and wrinkles, sagging, dullness, uneven tone, rough texture, discoloration, etc. The compositions may be applied topically once, twice, or more daily, in one embodiment once a day. The daily application may be applied for a period of one week, two weeks, four weeks, or more.

[00084] The compositions may be formulated into liposomes which can comprise other additives or substances, and/or which can be modified to more specifically reach or remain at a site following administration. The compositions of the present invention yield improvements to the aesthetic appearance by treating at least one of the unwanted features related to skin aging or damage.

[00085] Another embodiment of the method of the current invention encompasses compositions comprising a cosmetically or dermatologically acceptable formulation which is suitable for contact with living animal tissue, including human tissue, with virtually no adverse physiological effect to the user. Compositions embraced by this invention can be provided in any cosmetically and/or dermatologically suitable form, in one embodiment as a lotion or cream, but also in an anhydrous or aqueous base, as well as in a sprayable liquid form. Other suitable cosmetic product forms for the compositions used in this invention include, for example, an emulsion, a cream, a balm, a gloss, a lotion, a mask, a serum, a toner, an ointment, a mousse, a patch, a pomade, a solution, a spray, a wax-based stick, or a towelette. In addition, the compositions can include one or more compatible cosmetically acceptable adjuvants commonly used and known by the skilled practitioner, such as colorants, fragrances, emollients, humectants, preservatives, vitamins, chelators, thickeners, perilla oil or perilla seed oil (WO 01/66067 to a "Method of Treating a Skin Condition," incorporated herewith in its entirety for all purposes) and the like, as well as other botanicals such as aloe, chamomile, and the like, and as further described below.

[00086] Also, embraced by the invention are transdermal modes of delivery, such as patches and the like, with or without a suitable penetration enhancer. The methods and compositions embodied by the invention provide a means by which the Serissa japonica components can be effectively administered in a transdermal system. Accordingly, a transdermal means of delivering a composition or formulation (often with a penetration enhancing composition) to the skin is that of the transdermal patch or a similar device as known and described in the art. Transdermal patches are designed to deliver an effective amount of compound across a user's skin. Transdermal patches typically involve a liquid, gel, solid matrix, or pressure-sensitive adhesive carrier into which the Serissa japonica extract may be incorporated. Patch formulations and preparations are well known in the art. See for example "Dermatological and Transdermal Formulations" (Drugs and the Pharmaceutical Sciences, Vol 1 19) by Kenneth A Walters (Editor), Marcel Dekker and "Transdermal Drug Delivery" (Drugs & the Pharmaceutical Sciences) by Richard H. Guy (Editor), Jonathan Hadgraft (Editor) 2nd Rev & ex edition Marcel Dekker and "Mechanisms of Transdermal Drug Delivery" (Drugs & the Pharmaceutical Sciences, Vol 83) edited by Russell O. Potts and Richard H. Guy (1997). Examples of such devices are disclosed in U.S. Pat. Nos. 5,146,846; 5,223,262; 4,820,724; 4,379,454; and 4,956,171 ; and U.S. Patent Publication No. US201 10300198, all of which are incorporated herein by reference in their entirety and such descriptions are not meant to be limiting. The transdermal mode of storing and delivering the compositions onto the skin, including hair, and forming the active composition is convenient and well-suited for the purposes of an embodiment of the present invention. In a in one embodiment method, the application occurs through a sustained release vehicle, carrier, or diluent, e.g., a topically applied sustained released patch. In one embodiment, when a topical patch is used, the patch is applied to the desired area for extended period of time. In one embodiment, the extended period of time is greater than one hour, most in one embodiment the extended period of time is overnight, i.e., when the user is sleeping. Additionally, the transdermal patches may be formulated to provide extended benefits for a period of about 1 -7 days, in one embodiment, about 2 to 7 days, and more in one embodiment about 3-7 days. Such extended wear patches may be particularly well suited to treat, ameliorate, and/or prevent discoloration. Further, given that many compounds that lighten skin pigmentation/color are UV sensitive the transdermal patch may be used to permit continued treatment while wearer is exposed to sunlight thereby providing the wearer with greater freedom. In such instances, the exterior of the transdermal patch is in one embodiment flesh colored, and more in one embodiment the patch should closely match the skin color of the wearer to provide discreet treatment.

[00087] The topical compositions can include one or more cosmetically acceptable vehicles. Such vehicles may take the form of any known in the art suitable for application to skin and may include water (e.g., deionized water); vegetable oils; mineral oils; esters such as octal palmitate, isopropyl myristate and isopropyl palmitate; ethers such as dicapryl ether and dimethyl isosorbide; alcohols such as ethanol and isopropanol; fatty alcohols such as cetyl alcohol, cetearyl alcohol, stearyl alcohol and biphenyl alcohol; isoparaffins such as isooctane, isododecane and is hexadecane; silicone oils such as cyclomethicone, dimethicone, dimethicone cross-polymer, polysiloxanes and their derivatives, in one embodiment organomodified derivatives; hydrocarbon oils such as mineral oil, petrolatum, isoeicosane and polyisobutene; polyols such as propylene glycol, glycerin, butylene glycol, pentylene glycol and hexylene glycol; waxes such as beeswax and botanical waxes; or any combinations or mixtures of the foregoing.

[000127] Method of Treating Aging or Aged skin

[000128] The invention provides a method for treating aging skin by topically applying a composition comprising an extract of Serissa japonica, in one embodiment in a cosmetically acceptable vehicle, over the affected area for a period of time sufficient to reduce, ameliorate, reverse or prevent dermatological signs of aging. This method is particularly useful for treating signs of skin photoaging and intrinsic aging.

[000129] Generally, the improvement in the condition and/or aesthetic appearance is selected from the group consisting of: reducing dermatological signs of chronological aging, photo-aging, hormonal aging, and/or actinic aging; preventing and/or reducing the appearance of lines and/or wrinkles; reducing the noticeability of facial lines and wrinkles, facial wrinkles on the cheeks, forehead, perpendicular wrinkles between the eyes, horizontal wrinkles above the eyes, and around the mouth, marionette lines, and particularly deep wrinkles or creases; preventing, reducing, and/or diminishing the appearance and/or depth of lines and/or wrinkles; improving the appearance of suborbital lines and/or periorbital lines; reducing the appearance of crow's feet; rejuvenating and/or revitalizing skin, particularly aging skin; reducing skin fragility; preventing and/or reversing of loss of glycosaminoglycans and/or collagen; ameliorating the effects of estrogen imbalance; preventing skin atrophy; preventing, reducing, and/or treating hyperpigmentation; minimizing skin discoloration; improving skin tone, radiance, clarity and/or tautness; preventing, reducing, and/or ameliorating skin sagging; improving skin firmness, plumpness, suppleness and/or softness; improving procollagen and/or collagen production; improving skin texture and/or promoting retexturization; improving skin barrier repair and/or function; improving the appearance of skin contours; restoring skin luster and/or brightness; minimizing dermatological signs of fatigue and/or stress; resisting environmental stress; replenishing ingredients in the skin decreased by aging and/or menopause; improving communication among skin cells; increasing cell proliferation and/or multiplication; increasing skin cell metabolism decreased by aging and/or menopause; retarding cellular aging; improving skin moisturization; enhancing skin thickness; increasing skin elasticity and/or resiliency; enhancing exfoliation; improving microcirculation; decreasing and/or preventing cellulite formation; and any combinations thereof.

[000130] In one embodiment, the invention provides a method for treating discolored skin by topically applying a composition comprising an extract of Serissa japonica, in one embodiment in a cosmetically acceptable vehicle, over the affected area for a period of time sufficient to reduce, ameliorate, reverse or prevent discoloration of the skin. This method is particularly useful for treating discoloration resulting due to photoaging and intrinsic aging. Generally, the improvement in the condition and/or aesthetic appearance of a discoloration of skin is selected from the group consisting of: bleaching hyper-pigmented hair, skin, lips and/or nails; reducing age spots; evening or optimizing skin discoloration; improving the appearance of dark circles under the eyes; treating melasma, cholasma, freckles, after-burn scars, and post-injury hyper-pigmentation; bleaching hair on the scalp, legs, face, and other areas where bleaching and color reduction are desired; reducing melanin production, and/or bleaching nail stains.

[000131 ] In certain embodiments, a composition comprising an extract of Serissa japonica may be applied to counter the side effects of various pharmaceuticals know to exacerbate the effects of ageing upon the skin, in particular those known to discolor the skin. These pharmaceuticals include, but are not limited to, antibiotics (sulfonamides and tetracyclines), diuretics, nonsteroidal antiinflammatory drugs, pain relievers, psychoactive medications, oral contraceptives, antiepileptic agents (hydantoins), chloroquine, DOPA therapy (Levodopa), heavy metals (drugs containing arsenic, bismuth, gold, or silver), and/or chemotherapy agents (cyclophosphamide, 5-fluorouracil, doxorubicin, daunorubicin, and bleomycin). Compositions comprising an extract of Serissa japonica may be applied prior to, simultaneously with, or following administration of the pharmaceutical.

[000132] The composition will typically be applied to the skin one, two, or three times daily for as long as is necessary to achieve desired anti-aging results. The treatment regimen may comprise daily application for at least one week, at least two weeks, at least four weeks, at least eight weeks, or at least twelve weeks. Chronic treatment regimens are also contemplated. [000133] A composition comprising an extract of Serissa japonica is topically applied to an "individual in need thereof," by which is meant an individual that stands to benefits from reducing visible signs of skin damage or aging. In a specific embodiment, the Serissa japonica extract is provided in a pharmaceutically, physiologically, cosmetically, and dermatologically-acceptable vehicle, diluent, or carrier, where the composition is topically applied to an affected area of skin and left to remain on the affected area in an amount effective for improving the condition and aesthetic appearance of skin.

[000134] In one embodiment, methods for treating fine lines and wrinkles comprise topically applying the inventive compositions comprising a Serissa japonica extract to the skin of an individual in need thereof, e.g., topically application directly to the fine line and/or wrinkle in an amount and for a time sufficient to reduce the severity of the fine lines and/or wrinkles or to prevent or inhibit the formation of new fine lines and/or wrinkles. The effect of a composition on the formation or appearance of fine lines and wrinkles can be evaluated qualitatively, e.g., by visual inspection, or quantitatively, e.g., by microscopic or computer assisted measurements of wrinkle morphology (e.g., the number, depth, length, area, volume and/or width of wrinkles per unit area of skin). This embodiment includes treatment of wrinkles on the skin of the hands, arms, legs, neck, chest, and face, including the forehead.

[000135] It is also contemplated that the compositions of the invention will be useful for treating thin skin by topically applying the composition to thin skin of an individual in need thereof. In some embodiments, the treatment is for thin skin in men, whereas other embodiments treat thin skin in women, pre-menopausal or postmenopausal, as it is believed that skin thins differently with age in men and women, and in particular in women at different stages of life.

[000136] The method of the invention may be employed prophylactically to forestall aging including in patients that have not manifested signs of skin aging, most commonly in individuals under 25 years of age. The method may also reverse or treat signs of aging once manifested as is common in patients over 25 years of age.

[000137] EXAMPLES [000138] The following examples describe specific aspects of the invention to illustrate the invention but should not be construed as limiting the invention, as the examples merely provide specific methodology useful in the understanding and practice of the invention and its various aspects.

[000139] Example 1

[000140] Preparation of Serissa japonica Extract

[000141 ] I. Preparation of purified plant extract

[000142] Extraction Protocol 1

[000143] 250 g of dried and powdered material derived from the leaves and stems of Serissa japonica was percolated with 1000 ml EtOH/H ₂ 0 (50:50, v/v) at room temperature for 24 hours. This percolation was repeated 2 times and then the EtOH/H ₂ 0 extraction solution was concentrated under vacuum by rotary evaporator at 40-50 °C to 150 ml or end of distillation, whichever occurs first.

[000144] The concentrated solution was then diluted with pure water to 1500 ml of volume and sonicated for 20 minutes to generate an aqueous suspension. The suspension was left to stand at 4°C for 12 h and then centrifuged. The supernatant was then transferred to a separation funnel where three separate extraction were done with 500 ml of hexane each. The hexane solvent was recycled, and the hexane extract was discarded.

[000145] Charcoal (10% by w. vs. total dry matter content) was then added to the aqueous phase yielded from the hexane extraction and stirred for 1 hour. The solution was then filtered and concentrated under vacuum at 40-50 °C to adjust the concentration of solution to 5% (w/v) of its dry matter. The adjusted solution was then passed through a Diaion HP-20 column (20 times of the dry weight,) and washed successively with:

[000146] 1 ) H20: 2 times Diaion HP-20 column volume (100 g HP-20 is equal to 210 ml of column volume);

[000147] 2) 20% aqueous EtOH :2 times Diaion HP-20 column volume;

[000148] 3) 50% aqueous EtOH: 2 times Diaion HP-20 column volume;

[000149] 4) 95% aqueous EtOH: 3 times Diaion HP-20 column volume. [000150] The elutents of washes 1 -4 were concentrated, respectively, to dryness to obtain fractions 1 -4.

[000151 ] Extraction Protocol 2

[000152] Extraction Protocol 2 (exemplary)

[000153] An amount (g) of chopped Serissa japonica flowers may be gathered and pulverized. Subsequently, reflux extraction, using methods known to those of ordinary skill in the art, may be conducted using 8-1 Ox the weight of the pulverized flowers of water at 100° C. This step may be repeated. The resulting extract may be filtered and condensed using methods known to those of ordinary skill in the art, after which the extract may undergo vacuum distillation at appropriate conditions known to those of ordinary skill in the art. Subsequently, the extract may be mixed with a suitable amount of dextrin and spray dried.

[000154] As noted in the remaining specification, modifications and adaptations of the above-noted extraction process are possible, particularly during a scale-up to larger volumes for production.

[000155] II. HPLC The extract of Extraction Protocol I was characterized by high performance liquid chromatography. A sample size of approximately 5mg/ml_ was dispersed in 25/75 MeOH/H ₂ 0 and sonicated. The characterization was performed on a Zorbax SBC-18 column (7.5cm x 4.6mm, 3.5um particle size) and detection was achieved using diode array UV absorbance, 260 nm 300 nm and 360nm, with lines on FIG. 1 depicted in ascending order and 260 nm on bottom. Operating conditions were flow rate 1 .5 ml/min; temperature, 40° C; sample injection volume, 20 μΙ_, and time of run, 19 minutes. The mobile phase gradient used was as follows. The HPLC characterization of the extract is displayed in FIG. 1 . In one embodiment, the extracted composition of the present invention, in substantial isolation, exhibits an HPLC profile substantially similar to that depicted in FIG. 1 .

[000157] Example 2

[00153] In vivo up-requlation of skin biomarkers.

Botanical extracts of Serissa japonica were tested for the ability to upregulate skin biomarkers in vivo. 20 healthy female Caucasian subjects aged 30-65 with skin type II or II I and mild to moderate photo damage were treated with ingredients on the dorsal forearm for 3 weeks (3 consecutive rounds of 5 x 24 hour patches under semi-occlusion). Test articles and vehicles were applied in a randomized allocation on five sites on each forearm. Each subject was treated with the extract of Serissa japonica at a concentration of 0.2% formulated in Propylene Glycol/Ethanol/H ₂ 0 (65:25:10) vehicle and the vehicle control. The application dose was 2 mg/cm ² . After treatment, a 2 mm punch biopsy was obtained from each treatment site and fixed in 10% buffered formalin. Tissue samples were then embedded in paraffin, sectioned (5 micrometer thickness), processed and stained for the following skin markers - Total Collagen (by Masson Trichrome), Pro-collagen, and Hyaluronic Acid Binding Protein (HABP). In addition, epidermal thickness was evaluated. For each marker, the treated site was compared to the vehicle site to determine the difference in the intensity of the marker. If the intensity of the marker in the treated site is higher relative to control, it indicates improvement of that biomarker. Table 2 shows the percent of subjects that had an improvement in the tested skin biomarkers after three weeks of treatment with an extract of Serissa japonica.

TABLE 2. Percent of subjects that had an improvement in the tested skin biomarkers after three weeks of treatment with an extract of Serissa japonica

(Thumb.)

[00154] The botanical extract of Serissa japonica upregulated several biomarkers, such as epidermal thickening (52.8% of subjects exhibited an increase), collagen (61 .1 % of subjects exhibited an increase), pro-collagen (58.3% of subjects exhibited an increase), and hyaluronic acid binding protein (51 .4% of subjects exhibited an increase), in vivo when topically applied to skin. It is believed that the up-regulation of these biomarkers, which decline in aging skin, leads to an improvement in the appearance of aging or aged skin.

[000156] Example 3

[000157] Evaluation of Pigment inhibiting activity in vitro.

[000158] B16 mouse melanoma cells (cell line: ATCC, cat. #: CRL-6475) were grown in DMEM in 96-well tissue culture treated dishes. Cells were exposed to diluted test material or vehicle control for 7 days. Following the treatment period, the level of pigment produced was quantified in the medium using a spectrophotometer at 540nm. Percent inhibition of pigment production by the test active was calculated relative to vehicle control. Serissa japonica (@ 0.01 %) inhibited pigment production in the range of about 21 -40% relative to the untreated cell cultures (controls).
