The role and efficacy of α-arbutin:
1. Whitening and depigmentation
Tyrosine is the raw material for the formation of melanin. Tyrosinase is the main rate-limiting enzyme for the conversion of tyrosine to melanin. Its activity determines the amount of melanin formed. That is, the higher the tyrosinase activity in the body, the more the content, the easier it is to form melanin. Arbutin can produce competitive and reversible inhibition of tyrosinase, which can inhibit the production of melanin and achieve the effects of whitening, skin lightening and freckle removal.
2. Sunscreen
Arbutin also has the effect of absorbing ultraviolet rays. Some researchers have conducted special tests on sunscreen products added with arbutin, and found that arbutin shows a certain ultraviolet absorption capacity.
