Tea polyphenols can prevent skin albumen from oxidation and avoid forming brown pigment, so it is added in cosmetic. In addition, It is a kind of fine additive materials for the health of skin of human body because of the functions of restraining bacterium, diminishing inflammation and anti-radiation.
