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.

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™ 3LGA, "Ceramide Promoter", 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. In addition to providing excellent skin-moisture and inhibitory effect on melanin production, Amitose™ 3LGA improves skin barrier functions in an unprecedented way. Indeed, this complexe ascorbic acid derivative greatly increases ceramide synthesis which is one of the most important elements in the skin barrier mechanism. The increase in ceramide thickens the lamellar structure of the stratum corneum and greatly decreases transpidermal water loss. Furtermore, Amitose™ 3LGA also boosts the intracellular antioxidant system by removing reactive oxygen species (ROS) thus providing enhanced anti-pollution effect. The way this antioxidant mechanism works is unique to Amitose™ 3LGA and is highly effective even at low dosage. Lastly, we observed an inhibition of nerve fiber elongation which leads to a decrease in skin sensitivity. Amitose™ 3LGA can be used in gel serums and emulsions such as creams. This product is preservative free. It is developed and manufactured in Japan by SEIWA KASEI.
