Amitose HGA

SEIWA KASEI CO., LTD. makes their documentation available in the regions indicated below:

Amitose HGA, "Lightening vitamin C", is a novel stable vitamin C derivative produced by binding Vitamin C (ascorbic acid), glycerin and an alkyl group together using SEIWA KASEI's original technology. It provides excellent skin moisture but particularly excels at skin lightening. In fact, Amitose HGA skin lightening mechanism is the world first of its kind. First, it inhibits melanin synthesis more effectively than most ascorbic acid derivatives. Secondly, Amitose HGA inhibits and reverses melanin transport. Lastly, melanin is degraded by autophagy which won the 2016 Nobel Prize. Those mechanism leads to consequently supress dark spots, a truly unique mechanism in Vitamin C derivatives. Amitose HGA can be used in a large variety of formulae : skin toners, transparent gel-serums and emulsions such as creams. This product is preservative free water-soluble ingredient. It is developed and manufactured in Japan by SEIWA KASEI.
