3-O-Ethyl Ascorbic Acid
No Known RisksA 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.

How to use this assessment
The risk band is the primary conclusion. The score adds detail within that band and should not be used to compare products as if a one-point difference were clinically meaningful.
MamaSkin provides pregnancy-focused information, not medical advice. Your midwife, GP, pharmacist or dermatologist should take priority when your circumstances differ from typical cosmetic use.
