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.

What is ascorbyl tetraisopalmitate?
Ascorbyl tetraisopalmitate is an oil-soluble derivative of vitamin C formed by esterifying ascorbic acid with fatty acids. It is designed to deliver vitamin C benefits with enhanced stability and compatibility in lipid-based formulations.
What is ascorbyl tetraisopalmitate used for?
Ascorbyl tetraisopalmitate is commonly used in skincare products for brightening, antioxidant protection, and supporting a more even skin tone. It is frequently included in anti-aging and protective formulations, especially oil-based or anhydrous products.
How is ascorbyl tetraisopalmitate different from ascorbic acid?
Unlike pure ascorbic acid, ascorbyl tetraisopalmitate is oil soluble and much more stable against oxidation. It can penetrate the skin more easily and is often better tolerated, especially in leave-on formulations.
Is ascorbyl tetraisopalmitate suitable for sensitive skin?
Ascorbyl tetraisopalmitate is generally considered gentle and suitable for sensitive skin due to its stability and low irritation potential. However, individual skin response may vary, and patch testing is recommended.
Is ascorbyl tetraisopalmitate safe for cosmetic use?
Ascorbyl tetraisopalmitate is considered safe for cosmetic use when formulated within recommended concentration limits and in compliance with applicable cosmetic regulations.
