Tetrahexyldecyl Ascorbate (THDA)
A stable, oil-soluble form of Vitamin C that penetrates the skin more deeply than traditional Vitamin C. Known for its antioxidant properties, it helps brighten the complexion, reduce hyperpigmentation, and boost collagen production, which improves skin elasticity and reduces fine lines. THDA is gentler on the skin compared to ascorbic acid, making it suitable for sensitive skin types while still providing anti-aging, brightening, and protective benefits.
