3-O-Ethyl-L-Ascorbic Acid, also known as Vitamin C Ethyl Ether, is a derivative of Vitamin C (L-Ascorbic Acid) where an ethyl (C₂H₅) group replaces the hydroxyl group at the 3-position of the Vitamin C molecule. Compared to traditional Vitamin C, 3-O-Ethyl-L-Ascorbic Acid has superior stability, especially in cosmetics and skincare products, effectively preventing the oxidation of Vitamin C.
Due to its strong stability, 3-O-Ethyl-L-Ascorbic Acid is widely used in skincare products and has various skin benefits, particularly in brightening, antioxidant, and anti-aging effects.
