How SymWhite 377 Works In Cosmetic Formulations
SymWhite 377 competitively binds to tyrosinase active site, blocking key enzymatic reaction of melanin synthesis, so as to restrain excessive melanin formation and deposition in skin layers. Meanwhile, it scavenges free radicals to reduce UV-triggered pigmentation risk.
Note: SymWhite 377 is sensitive to light and high-alkaline environment. Formulators need to conduct pH adjustment, stability test and finished-product safety assessment. Final effect depends on formula system, dosage and matched auxiliary ingredients.
