The highly effective Medik8 C-Tetra Luxe antioxidant serum helps combat wrinkles and fine lines, boosts skin radiance and supports a visibly more even-looking complexion. With twice the concentration of vitamin C compared to the original C-Tetra serum, this formula delivers enhanced brightening and rejuvenating effects. The formula contains 14% tetrahexyldecyl ascorbate, a stabilised yet effective form of vitamin C that ensures efficacy while minimising the risk of irritation. Vitamin C helps neutralise free radicals and protects against environmental influences that contribute to premature ageing. It also plays a role in brightening the complexion and evening out skin tone, reducing visible discolouration and improving overall skin clarity. Despite its high concentration of vitamin C, the serum remains gentle on the skin. It is recommended for most skin types and works particularly well for dry and dehydrated skin.
