Tetrahexyldecyl Ascorbate (Vitamin C)

Tetrahexyldecyl Ascorbate (THDA) is a stable, oil-soluble derivative of Vitamin C prized for its excellent skin compatibility and antioxidant properties. Unlike traditional L-ascorbic acid, THDA does not require a highly acidic formula, making it a gentle and versatile way to incorporate Vitamin C into skincare.

THDA helps brighten the appearance of dull, uneven skin tone while supporting a smoother, more luminous complexion. Its antioxidant properties also help defend the skin against oxidative stress caused by environmental exposure.

Because THDA is oil-soluble, it pairs beautifully with botanical oils and other lipid-soluble antioxidants, making it especially well suited to nourishing facial oils and elixirs.

BENEFITS: Antioxidant • Brightening • Smoothing • Supports even-looking skin tone
