3-O-Ethyl Ascorbic Acid is a stabilized derivative of vitamin C, developed to offer high antioxidant efficacy with greater stability and formulation compatibility compared to conventional ascorbic acid. It is a multifunctional active ingredient widely recognized for its antioxidant, brightening, and anti-aging properties.

This water- and oil-soluble derivative allows for better skin penetration and greater resistance to oxidation, while maintaining the bioactivity of vitamin C. It acts as a powerful antioxidant, neutralizing free radicals, protecting the skin against oxidative stress, and stimulating collagen synthesis, which helps improve skin firmness, elasticity, and texture.

Furthermore, 3-O-Ethyl Ascorbic Acid helps to even out skin tone, reduce hyperpigmentation, and brighten the complexion, making it a key ingredient in formulations for dull, photo-aged, or blemished skin. Its excellent stability in aqueous formulations and emulsions makes it a preferred alternative to pure vitamin C in advanced cosmetic products.

This active ingredient is especially valued in brightening serums, anti-aging treatments, dermocosmetics and daily care products, where it contributes to improving the overall appearance of the skin and providing a more even and radiant tone.
