    3-O-ethyl-L-Ascorbic Acid More Info

    3-O-Ethyl-L-Ascorbic Acid is a chemically synthesized, highly stable derivative of Vitamin C (L-Ascorbic Acid). It is a water-soluble, white to off-white crystalline powder widely used in high-end skin care and cosmetic formulations.

    Unlike traditional Vitamin C, which is notoriously unstable and prone to oxidation, Ethyl Ascorbic Acid features an ethyl group attached to the hydroxyl group at the C3 position. This structural modification significantly enhances its stability while maintaining excellent bioavailability and efficacy.

    Key Features & Benefits

    Superior Stability:

    It remains stable in aqueous solutions and is resistant to light, heat, and oxidation. Unlike standard Vitamin C, it does not easily turn yellow or brown when exposed to air, ensuring the shelf-life of cosmetic products.

    Excellent Skin Penetration:

    The ethyl group acts as a "carrier," helping the molecule penetrate the stratum corneum (the outer layer of the skin) more efficiently than pure Vitamin C. Once inside the skin, enzymes metabolize it, releasing active Vitamin C.

    Potent Whitening & Brightening:

    It inhibits the activity of tyrosinase, a key enzyme in melanin production. This makes it highly effective for reducing hyperpigmentation, age spots, freckles, and melasma, resulting in a brighter, more even skin tone.

    Antioxidant Protection:

    It scavenges free radicals and reactive oxygen species (ROS), protecting the skin from UV-induced damage and preventing premature aging.

    Collagen Synthesis:

    By converting to L-Ascorbic Acid in the dermis, it promotes the synthesis of collagen and elastin, helping to improve skin elasticity and reduce the appearance of fine lines.
