Everything You Want Gathered Under One Roof-From Cosmetic Raw Materials To Nutritious Supplementary
Products Description
Phenylethyl Resorcinol is a white organic compound. Its discovery originated from the chemical modification of silver pinus (a whitening ingredient naturally present in the cones of European red pine). German researchers finally screened out this new and highly effective whitening active ingredient and named it SymWhite 377. It mainly achieves whitening by inhibiting the activity of tyrosinase and is widely used in cosmetics such as whitening, freckle removal, and anti-aging.
