[ Application]
Arbutin is the active substance originated from natural plant which can whiten and lighten skin. It can infiltrate into the skin quickly without affecting the concentration of cell multiplication and effectively prevent activity of tyrosinase in the skin and the forming of melanin. By combined Arbutin with tyrosinase, decomposition and drainage of melanin are accelerated, splash and fleck can be got ride of and no side effects are caused. It is one of the safest and most efficient whitening materials that are popular at present. It is also the most competitive whitening activity.
As a skin lightening agent, Arbutin has by far higher stability than hydroquinone, and nevertheless, is decomposed into hydroquinone and glucose rapidly in the presence of the enzyme hydrolase in the skin and exhibits the remedying effect to melanosis. It causes no irritation, scarce sensitization, which permits continuous use for a long period of time in high concentration to develop satisfactory skin lightening effects. Features of the product:
It restrains the melanogenesis through the cells poisoning reaction on melanin cells, and the blocking
mechanism on tyrosinase.
It can diminish the senile yellowish brown plaque, also effective for lentigines diminishing.
It can evidently diminish the pigmentation caused by ultra-violet radiation.
4It can improve the metabolism of sunburn skin caused by radiation.
Applications in all cosmetic and personal care products. Use levels: 1-5% .
