Symwhite 377 is an effective whitening ingredient, has a strong antioxidant effect, strongly inhibits the activity of tyrosinase, thereby reducing the production of melanin. Skin tests have shown that 0.5% concentration of 377 is more effective than 1% concentration of kojic acid when it is not exposed to light. Existing studies have shown that Symwhite 377 can effectively whiten the skin when the dosage is over 0.5%, and at the same time can effectively resist oxidation and wrinkle. In 2012, the China Food and Drug Administration (SFDA) approved Symwhite 377 as a cosmetic raw material for use in cosmetics.
