This invention relates to a skin care composition comprising extract, for example the juice, from Kalanchoe daigremontiana for topical administration to human skin. In particular, the invention relates to a method of making such a composition and to cosmetic and medical uses thereof.

BACKGROUND

In the field of skin care, a wide variety of products have been developed and commercialised for enhancing skin condition. Such products are typically formulated as gels, creams, rinses, film-forming compositions, transdermal patches, sprays, or pastes aimed at providing easy application to the skin and effective absorption of components in the formulation. Such formulations must also be stable for reasonable storage periods.

However, the art is continually seeking improved solutions wherein a skin care product both enhances skin condition and is particularly effective in the treatment of one or more common medical complaints associated with the skin. For example, compositions formulated to combat common adverse dermal disorders such as dermatitis, acne, rosacea, psoriasis, atopic dermatitis and/or allergic contact dermatitis. Skin products directed at alleviating dermal disorders may therefore also frequently include a therapeutically active agent, such as a naturally derived plant extracts, such as aloe vera, or a manufactured ingredient or chemical, such as benzoyl peroxide or hexachlorophene.

In the case of some particular dermal complaints, such as psoriasis and atopic dermatitis, the routinely used treatment prescribed by dermatologists includes application of a formulation comprising a glycocorticosteroid. Steroids are prescription drugs and require frequent application of 1 to 3 times per day for at least 2 weeks. However, steroids are undesirable for a number of reasons: they are expensive for the patient and/or health services and often lead to serious side effects which include inter alia: systemic hormonal changes, skin atrophy, eczema, steroid acne, erythema, vascular purpura, telangiectasia, skin irritation, e.g. burning sensation, reddening, extreme dryness and sometimes bacterial or mycotic superinfections. Moreover, the curative effects of steroids are short-term and after the end of the treatment period the lesions and other physical symptoms associated with psoriasis and atopic dermatitis can re-appear in an aggravated form. Other treatment options for dermal conditions such as psoriasis include compositions comprising urea, salicylic acid and/or lactic acid. However, these treatments fail to provide a sufficient long term solution for patients; they reduce the superficial appearance of squama on the surface of psoriatic plaque but do not prevent or alleviate regenerating lesions or allow the skin to heal fully. Further, by using such preparations, skin cannot be exposed to sunlight.

Although, medicinal plants are commonly applied in the field of topical formulations, there is a continuing need to identify extracts and develop useful formulations of those extracts to yield solutions for both skin enhancement and clinical treatment of common dermatological conditions. This is particularly true of skin psoriasis, which affects from 1 to 3% of the population. Polish patent application no. PL 398082 discloses a composition which contains from 36% to 52% w/w of phyto product in the form of juice or leaf pulp of two plants: Kalanchoe daigremontiana and Kalanchoe pinnata. It is disclosed that the composition improves animal health and condition. For example: poultry resistance to pathogens is greater and the susceptibility to pathogens (microorganisms) is reduced. However, there is no indication that such extracts from either of these plants would be useful in the health of humans or be useful in the treatment of a particular human condition.

The applicant has recognised a continuing need to identify and develop a product which enhances skin condition and provides a clinically effective treatment for common dermal complaints.

SUMMARY OF INVENTION

The present invention relates to skin care compositions comprising the extract from Kalanchoe daigremontiana for administration to human skin. The compositions are therapeutically effective for both skin conditioning and combating skin disorders.

The extract may include or comprise the juice of from Kalanchoe daigremontiana. The invention particularly concerns a composition for topical administration comprising a therapeutically effective amount of Kalanchoe daigremontiana extract. The extract may be derived from the juice of the pulp of the Kalanchoe daigremontiana plant and/or from the juice derived from the leaves and/or the stalk. In one embodiment, the composition is formulated with at least one cosmetically or pharmaceutically acceptable excipient.

The inventors have shown that such a composition is surprisingly useful in the regeneration and recovery of the natural protective layer of the skin. It is also shown that the composition is surprisingly effective in soothing irritation and inflammation of human skin.

Such a composition is advantageously also found to reduce or eliminate roughness, exfoliation, pulling and burning and soothes itching after a single application. The extract from Kalanchoe daigremontiana appears to be a highly effective active ingredient for re-conditioning and regenerating healthy skin cells. The composition of the invention containing Kalanchoe daigremontiana, therefore presents a new and surprising application in the area of topical plant- derived therapeutic compositions.

Preferably, the composition comprises 1-30% w/w of Kalanchoe daigremontiana extract or juice.

More preferably the composition comprises 5-15% w/w of Kalanchoe daigremontiana extract or juice, most preferably approximately 9-10% w/w.

Results

Both cosmetic and clinical trials of a cream formulation comprising an extract or juice of Kalanchoe daigremontiana were conducted.

The cream that was tested comprised the formulation of within the ranges specified in Example 4. In particular the test cream comprises:

34.4 g coconut oil (unrefined), 20 g glycerol monostearate, 35 g demineralized water, 9.6 g extract from Kalanchoe daigremontiana, 1 g phenoxyethanol.

Patient Compliance

The cream has the form of homogenous emulsion with properly selected consistency, which, in the opinion of the trial participants, enabled them to apply the cream evenly on body parts. The cream consistency and skin application ease was rated very well by the trial participants, they were able to spread it smoothly all over the skin. The participants were of the opinion that the cream is absorbed into the skin evenly and quickly (within 1 to 3 minutes) leaving a perceptible film and did not cause the feeling of stickiness or heaviness where applied.

Cosmetic hydration

The cream significantly improves the skin hydration and does not provoke skin pulling sensation, but softens and smooths the skin, at the same time reducing the skin roughness, itching, skin irritation, redness, rosacea and squama. The skin became supple and more pleasant to the touch after the one application of the cream. Clinical results and photographic evidence

The clinical results achieved in the following 7 symptomatic patients are provided in detail below. Further, photographic documentation, provided in the Figures 1 to 7, illustrates the observed effect of applying the cream with Kalanchoe daigremontiana before and after the clinical trials in each of these patients:

Condition/symptoms: psoriasis on the head in regions of ears, duration of illness: 28 years

(Previous treatment in hospital with steroids resulted in no improvement)

Results: 5 weeks (twice daily) - 85% clearance The following general conclusions regarding patient compliance and clinical effectiveness are made by the inventors - in particular, as it concerns the effectiveness and tolerance of the cream on the face and body: the cream soothes itching sensation after the first application (trial participants reported that itching symptoms reduced by 80% after the first application);

the cream significantly reduces or eliminates the lesions, treats irritations and inflammations (95% of the trial participants rated the cream efficacy as higher than the efficacy of other prescription-free products available on the market and clinical observations during trial and by 2 weeks of application there was reduced redness, psoriatic plaques, atopic or allergic eczema and/or the appearance of psoriatic laminae. Further, 70% of lesions presenting in patients, examined after 8-14 weeks of using the cream, found to be were clear, the remaining lesions had become paler and psoriatic laminae, atopic eczema or allergic eczema had disappeared);

the study suggests the cream reduces keratosis, eliminates squama from the surface of psoriasis lesions as early as 1 week of daily application;

the cream reduces the symptoms of skin irritation resulting from the use of detergents, chlorinated water (patients reported a feeling of relief and the feeling of soothing) if applied regularly, it may strengthen the natural skin defence barrier; and

no adverse reactions were seen - no irritation; reddening, swelling or burning during/after application was observed or experienced by patients in the trial.

In summary, the composition of the invention therefore effectively treats dermal conditions and in particular treats the irritations such as itching, symptoms of roughness, exfoliation and the pulling and burning sensation associated with those dermal conditions. The composition is effective in speeding up regeneration and recovery of the natural protective layer of the skin.
