Ascorbyl Tetraisopalmitate (ATIP) is a highly stable, oil-soluble Vitamin C derivative known for its strong brightening and anti-pigmentation efficacy. Compared with traditional Vitamin C, it is significantly more stable and less prone to oxidation, while effectively inhibiting tyrosinase and reducing melanin formation for a clearer, more even skin tone. Its lipophilic structure allows deeper skin penetration, further enhancing radiance and supporting antioxidant defense.

Supplied as a colorless to pale-yellow liquid, ATIP dissolves easily in oils and is ideal for serums, creams, face oils, and other oil-based formulations. Used at 0.5–4.0%, it provides potent brightening power with excellent formulation stability and skin tolerance.
