                            What does alpha arbutin powder do?

                            Arbutin generally appears in skin care product formulas as a composite whitening ingredient. Common ingredients that are paired with arbutin include niacinamide, vitamin C, and kojic acid.

                            1. Whitening and brightening
                              Arbutin is an active competitive inhibitor of tyrosinase. By directly binding to tyrosinase, it interferes with dark cells and inhibits the generation of darkening factors.
                            2. Lightening
                              Inhibits the formation of melanin from the source. This ingredient has the characteristics of "safety and high efficiency". It has the effect of lightening spots while whitening. It is suitable for chloasma, freckles, and sun spots.
                            3. α-Arbutin has a protective effect on UV-induced exogenous damage.
                              α-Arbutin can significantly reduce UV-induced erythema and wrinkles and protect collagen tissue.
                              Reduce the occurrence of inflammatory reactions, thus having good soothing and anti-aging effects.
