Composition for preventing or improving skin circadian rhythm disorder comprising tea tree extract

Abstract

The present specification relates to a composition comprising a Jangwon No. 3 tea plant extract as an active ingredient. The composition, by comprising the Jangwon No. 3 tea plant extract as the active ingredient, may provide an effect of improving time dependence of a cell proliferation cycle by normalizing expression of Bmal1, which is a clock gene. Through this, by changing a circadian rhythm in which much damage is caused by ultraviolet irradiation, inherent ultraviolet resistance of cells is enhanced, and side effects such as erythema due to ultraviolet rays can be prevented and improved.

Dependencies are inferred from the claim text.
