3-O-Ethyl Ascorbic Acid is a stable derivative of Vitamin C, renowned for its skin-brightening and anti-pigmentation properties. It effectively inhibits tyrosinase activity and disrupts melanin formation, helping to improve uneven skin tone and enhance skin radiance. Thanks to its excellent permeability and bioavailability, this active ingredient delivers visible results efficiently.

Fornecido como um white to off-white crystalline powder, it is solúvel em água, making it suitable for incorporation into serums, creams, lotions, and other water-based formulations. With a recommended usage of 0.5–3.0%, it provides potent brightening effects while maintaining formulation stability.
