COSMETICS COMPOSITION COMPRISING POLYGONI MULTIFLORI CAULIS EXTRACT FOR SHITENING SKIN

摘要

The present invention relates to a skin-whitening cosmetic composition containing a Polygoni multiflori Ramulus extract as an active ingredient. According to the present invention, the Polygoni multiflori Ramulus extract inhibits expression of gene encoding tyrosinase, tyrosinase related protein-1 (TRP-1), tyrosinase related protein-2 (TRP-2), or microphthalmia-associated transcription factor (MITF) while promoting activity of LIVER X RECEPTOR (LXR), thereby exhibiting skin-whitening effects by inhibiting melanin biosynthesis.
