Arbutin (4-hydroxyphenyl-D-glucopyranoside)
Arbutin, also known as arbutin, has a chemical formula of C12H16O7. It is an ingredient extracted from bearberry leaves of the Ericaceae plant. It can inhibit the activity of tyrosinase in the body and prevent the production of melanin, thereby reducing skin pigmentation. , removes spots and freckles, and also has bactericidal and anti-inflammatory effects. It is mainly used in cosmetics.
Extension:
Hydroquinone has the effect of inhibiting tyrosinase and was used in early anti-freckle and whitening cosmetics. However, hydroquinone has the risk of causing exogenous chloasma and vitiligo, and even the potential risk of sensitization and carcinogenesis. Therefore, the European Union and China have listed hydroquinone as a banned ingredient in cosmetics.
Arbutin has a similar structure to hydroquinone and has whitening effects. It is used in cosmetics as a tyrosinase inhibitor.
Arbutin is divided into three types: β-arbutin (Beta-arbutin), α-arbutin (alpha-arbutin) and deoxyarbutin (D-Arbutin). These three effects on the skin are very different.

The most important role
Whiten/brighten skin tone
▲ Arbutin can effectively inhibit tyrosinase activity. Through its direct binding to tyrosinase, it competes for the binding site of dopa, blocks the synthesis of dopa and dopa quinone, thereby interfering with melanocytes and inhibiting melanin. generate.
▲ At the same time, arbutin also has the effect of diluting the formed melanin, accelerating the decomposition and excretion of melanin, and reducing skin pigmentation.
▲ As the concentration of arbutin increases, its inhibitory effect on melanin production increases significantly.
extend
▲ Comprehensive comparison shows that α-arbutin is 10 to 15 times more effective at inhibiting melanin production than β-arbutin.
Anti-inflammatory repair
Arbutin also has analgesic and anti-inflammatory effects. The main raw material of common burn and scald medicines includes arbutin. If it is applied to the burned area, it can effectively reduce inflammation and swelling, and speed up wound healing. Arbutin is also commonly found in some acne treatment and other products.
