3-O-Ethyl Ascorbic Acid

No known risks

A stable ether derivative of vitamin C used as an antioxidant and brightening ingredient. Pregnancy-specific topical studies are limited, but no pregnancy-specific contraindication was identified in the reviewed literature. Published case reports describe allergic contact dermatitis, so local sensitivity remains possible and this classification should not be read as proof that irritation cannot occur.
