Senté® Defense C Serum

A Vitamin C serum that solves the two biggest problems with traditional Vitamin C formulas: instability and irritation. Defense C is formulated with 20% Tetrahexyldecyl Ascorbate (THD Ascorbate), a highly stable, lipid-soluble form of Vitamin C that penetrates more effectively than standard L-Ascorbic Acid and remains active throughout the product's lifecycle. Paired with Senté's patented Heparan Sulfate Analog (HSA), the formula delivers superior brightening, collagen support and environmental protection while actively enhancing skin tolerance and calming inflammation rather than provoking it.

Key Actives

• THD Ascorbate (20%): a potent, stable, lipid-soluble Vitamin C that brightens, supports collagen synthesis, inhibits melanin production and defends against free radicals and environmental damage without the oxidation or irritation of traditional Vitamin C
• Heparan Sulfate Analog (HSA): Senté's patented repairing molecule that works synergistically with THD Ascorbate to enhance tolerability, calm inflammation, stimulate collagen production and strengthen the skin barrier
• Antioxidant Brightening Blend (AOX): a supercharged antioxidant complex including Terminalia Chebula Fruit Extract, Rice Bran Extract, Sunflower Extract, Rosemary Extract and Vitamin E that protects against oxidative damage and visibly brightens skin
