What is Ethyl Ascorbic Acid and How is it Used in Cosmetics?
Ethyl Ascorbic Acid, also known as 3-O-Ethyl-L-Ascorbic Acid, is a stable derivative of Vitamin C designed to deliver the same powerful skin benefits with improved stability. It is widely used in skincare formulations for its brightening, anti-aging, and antioxidant properties. Ethyl Ascorbic Acid works by inhibiting melanin synthesis, which helps in lightening hyperpigmentation, while boosting collagen production, making skin appear firmer and more youthful. It is an excellent ingredient for brightening dull skin, reducing dark spots, and enhancing overall radiance.
