3-O-Ethyl Ascorbic Acid is a stable, water-soluble derivative of vitamin C (ascorbic acid) widely used in cosmetic and skincare formulations for its brightening, antioxidant, and anti-aging properties. The ethylation at the 3-O position improves its stability against oxidation, making it more durable in formulations compared with pure ascorbic acid.
