Arbutin

所在地： 　行业： 职位：

 

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:

1.       It restrains the melanogenesis through the cells poisoning reaction on melanin cells, and the blocking

mechanism on tyrosinase.

2.  It can diminish the senile yellowish brown plaque, also effective for lentigines diminishing.

3.  It can evidently diminish the pigmentation caused by ultra-violet radiation.

4.  It can improve the metabolism of sunburn skin caused by radiation.
