COSMETIC COMPOSITION COMPRISING QUERCUS ACUTA THUNB FRUIT EXTRACT FOR PREVENTING AND ALLEVIATING ULTRAVIOLET LIGHT-CAUSED SKIN AGING
Document Type and Number:
WIPO Patent Application WO/2021/206227
Kind Code:
A1
Abstract:
The present invention relates to a cosmetic composition comprising a Quercus acuta Thunb extract as an active ingredient for preventing and alleviating ultraviolet light-caused skin aging. It was observed that when treated with the control group UVB, HaCaT cells, which are a human epidermal keratinocyte line, increased in collagenase activity, compared to a normal group whereas, for a test group treated with UVB and a Quercus acuta Thunb extract together, collagenase activity decreased as the concentration of the Quercus acuta Thunb extract increased. Thus, the cosmetic composition for prevention and alleviation of ultraviolet light-caused skin aging according to the present invention has an excellent inhibitory effect on collagenase activity and can be used safely without toxicity and adverse effects.
