How it works C-Tetra®
- C-Tetra protects the skin from damage caused by free radicals, as it contains vitamin C to increase the skin's natural antioxidant defense levels. Vitamin C is a fundamental pillar of our CSA philosophy, as it is one of the most powerful vitamins for preventing signs of premature skin aging. Vitamin C also helps stimulate collagen production and can disrupt the overproduction of melanin to lighten the look of dark spots and uneven skin tone. The result? Visibly radiant, healthier and younger-looking skin. C-Tetra contains tetrahexydecyl ascorbate, a form of vitamin C that is a stabilized modification of ascorbic acid (the purest form of vitamin C) that is gentle on the skin but proven to deliver visible results.
- Vitamin C and vitamin E act synergistically as "network antioxidants", enhancing the overall antioxidant effect of the serum to keep the skin protected throughout the day.
- C-Tetra is based on jojoba seed oil, for light nutrition and an instant luminous look. This natural emollient oil glides effortlessly across the skin barrier, delivering the benefits of vitamin C with ease.
- The perfect pairWhen combined, vitamin C and sunscreen provide the skin with maximum protection from the sun and the environment throughout the day, to minimize signs of premature aging. Buy our recommended Advanced Day Total Protect day cream here.

Science
"It is exceptionally difficult to formulate a long-lasting vitamin C serum that maintains its power over time. It is notoriously unstable, sensitive to oxidation and can often turn yellow, indicating that it has been lost. Medik8's C-Tetra range uses an extremely stable form of vitamin C, called tetrahexyldecyl ascorbate. This molecule is altered to be less reactive to oxidation, meaning that even 6 months later you can be sure of your vitamin C. It's still as powerful as when you first opened it."
