TETRAHEXYLDECYL ASCORBATE (THDA)

Tetrahexyldecyl Ascorbate (THDA) is an advanced, oil-soluble derivative of Vitamin C known for its superior stability and deep skin penetration. Unlike traditional ascorbic acid, THDA is non-irritating and well-tolerated, even by sensitive skin types. It works to brighten the complexion, fade hyperpigmentation, boost collagen synthesis, and protect against oxidative stress.

THDA is ideal for use in serums, facial oils, creams, and emulsions where both antioxidant protection and anti-aging effects are desired. Its lipophilic nature allows it to penetrate the lipid layers of the skin, delivering Vitamin C directly to where it’s most effective—making it one of the most potent and skin-friendly Vitamin C derivatives available.
