Ascorbyl Tetraisopalmitate is a highly stable, non-irritating oil-soluble form of Vitamin C that delivers powerful antioxidant protection, supports skin firmness, and promotes a more radiant, even complexion. It penetrates deeply and is less irritating than pure ascorbic acid, making it ideal for all skin types including the sensitive skin.
Unlike traditional water-soluble Vitamin C derivatives, Ascorbyl Tetraisopalmitate is oil-soluble and more stable, allowing it to remain effective for longer periods in formulations. It absorbs efficiently into the skin and converts to active ascorbic acid inside cells, where it neutralizes free radicals and supports collagen production.
It is a stable, oil-soluble derivative of Vitamin C known for strong antioxidant activity. It helps brighten skin tone, support collagen synthesis, and protect against free radical damage.
L-Ascorbic Acid is water-soluble and unstable, while Ascorbyl Tetraisopalmitate is oil-soluble and much more stable. It penetrates lipid layers effectively, causes less irritation, and offers broader formulation flexibility, though it typically works more gradually than pure Vitamin C.
All skin types, including sensitive. Its lower irritation potential makes it a good option when water-based Vitamin C is too reactive.
