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. Kojic acid whitening active agent than other whitening agents have a better tyrosinase inhibitory effect. It does not act on the other biological enzymes in the cell, no toxic effects on the cells, but it can also enter the interstitial cells, composed of interstitial glia, play a role in water retention and increase skin elasticity.
