Use of Kojic acid

Whitening material of Cosmetics.
Kojic acid, also known as kojic acid, gallic acid, is a melanin-specific inhibitor, which enters the skin cells to complex with the copper ions in cells, changing the three-dimensional structure of tyrosinase and preventing the activation of tyrosinase , Thereby inhibiting the formation of melanin.
