3) It can activate macrophages that are capable of phagocytosis of melanin. Thereby it inhibits melanin formation, and has good whitening effect.

4) Tea Extract improves skin’s anti-allergic ability by inhibiting catalase. It has anti-inflammatory and anti-bacterial property. Thus it can be used in oral products to prevent tooth decay;

5) Tea Extract has an excellent inhibitory effect on microorganisms. It can be used in toner and face cream to prevent oil rancidity in cosmetics;

6) It can promote fat decomposition, and can be used in slimming products;
