Why it's Renude approved

This formula is loaded with a lipid-soluble form of Vitamin C (known as tetrahexyldecyl ascorbate), which improves skin radiance and offers antioxidant protection. The serum has a jojoba oil base, which is structurally very similar to the skin's natural sebum, so absorbs well and won't clog pores.

Restore radiance and fight visible signs of ageing with C-Tetra, a super-light daily vitamin C serum. Antioxidant power is provided through vitamin C and E. Together, these actives help to combat sun and pollution-induced damage. The lightweight, uplifting formula stimulates the production of collagen and elastin to help reduce fine lines and wrinkles, as well as visibly brightening the complexion and balancing skin tone. Using a lipid-soluble form of vitamin C called tetrahexyldecyl ascorbate, the formula penetrates deep into skin to provide powerful antioxidant protection with minimal irritation. C-Tetra has been carefully crafted in a water-free formula to be 100% stable, which means that the vitamin C does not degrade over time. This ensures that your formula remains highly potent from the very first use to the final drop.
