Amitose™ HGA, "Lightening vitamin C", is a novel stable vitamin C derivative produced by binding Vitamin C (ascrobic 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.

Amitose™ DGA, "Rich-Moisturizing vitamin C", is a novel stable vitamin C derivative produced by binding Vitamin C (ascorbic acid) and two glyceryl groups using SEIWA KASEI's original technology. In addition to inhibiting melanin production it provides ultra moisture to the skin as it strenghtens the cornified cell envelope in the stratum corneum. As a non-ionic ingredient it can be used easily in gel and emuslion formulae such as creams but it is also notably recommended for transparent gel-serums, Vitamin C-rich serum and skin toners. This product is preservative free water-soluble ingredient. It is developed and manufactured in Japan by SEIWA KASEI.

Amitose™ 2GA, "Moisturizing vitamin C", is a novel powder stable vitamin C derivative produced by binding Vitamin C (ascrobic acid) and glycerin using SEIWA KASEI's original technology. Besides the fact it can provide skin moisture and inhibit melanin production better than regular ascorbic acid derivatives, Amitose™ 2GA also improves skin feel and enhances collagen production. Lastly, unlike many acid ascorbic derivatives Amitose™ 2GA remains stable in a wide range of pH. This product is preservative free. It is developed and manufactured in Japan by SEIWA KASEI.
