THD Ascorbate

Tetrahexyldecyl ascorbate is lipid soluble, penetrating further into skin than traditional vitamin C. It works with the vitamin E naturally found in your skin to target its underlying support system via a different pathway than water-soluble ascorbic acid. This allows for the deepest delivery of vitamin C. Its oil-soluble nature helps improve the look of dark spots, age spots, and the appearance of melasma.
