Function 

1.α-Arbutin has a good therapeutic effect on scars caused by ultraviolet burns, and has good anti-inflammatory, repair and whitening effects. It can inhibit the production and deposition of melanin, remove stains and freckles.

2.The whitening mechanism of α-arbutin directly inhibits tyrosinase activity, thereby reducing the production of melanin, instead of inhibiting cell growth or tyrosinase gene expression to reduce melanin production

3.α-Arbutin can repair skin damage caused by ultraviolet rays, regain the skin's transparency, and is not easily decomposed by β-glucosidase on the skin surface. The effect is about 10 times that of β-arbutin, and it can stay on for a long time. Every corner of the skin continues to protect the skin from harm.

4.Melanin is the cause of dull skin. α-Arbutin can quickly penetrate deep into the skin and inhibit the activity of tyrosinase in the chromoblasts that exist deep in the stratum corneum. It also has a dual effect on the skin surface to inhibit the production of melanin.
