摘要：
Disclosed is a composition for whitening skin or improving skin wrinkles comprising black tea extract as an active ingredient. In a cell experiment for Melan-a cells and an animal experiment using the brown guinea pig model with artificial tanning spots induced by UVB, the black tea extract of the present disclosure greatly inhibited melanin synthesis. Also, in an experiment on SKH-1 hairless mouse, it remarkably inhibited wrinkle formation. Accordingly, the composition of the present disclosure can be developed as a skin whitening agent, an anti-wrinkle agent or a medicine for treating diseases associated with melanin hyperpigmentation, e.g. liver spots, freckles, senile spots or solar lentigo.
