3-O-Ethyl Ascorbic Acid
What is 3-O-Ethyl Ascorbic Acid?
Ethyl Ascorbic Acid is a stable, water-soluble derivative of L-ascorbic acid (Vitamin C) where an ethyl group is attached to the third carbon position, enhancing its stability against oxidation and degradation compared to pure ascorbic acid. It penetrates the skin more effectively due to its lipophilic nature while retaining the antioxidant properties of Vitamin C, making it suitable for use in a wide range of skincare formulations including serums and creams. Once absorbed, it is slowly hydrolyzed by enzymes in the skin to release active ascorbic acid, providing brightening and anti-aging benefits.
