C-Tetra® Luxe by Medik8 is an advanced lipid serum with 14% stabilised vitamin C, created for enhanced radiance, even skin tone and powerful antioxidant protection. The formula contains twice as much vitamin C as the original C-Tetra® and helps the skin look brighter, smoother and more youthful from the very first applications.

At the heart of the serum is tetrahexyldecyl ascorbate, a stable lipid-soluble form of vitamin C with a low risk of irritation. It helps reduce the appearance of pigmentation, supports collagen production and improves overall skin tone. Optimised red ginseng extract boosts radiance and supports a fresher, more energised look, while vitamin E complements antioxidant protection and enhances the effectiveness of vitamin C.

C-Tetra® Luxe also contains squalane and maracuja oil, which nourish the skin, support the lipid barrier and help maintain softness, smoothness and comfort. The velvety texture absorbs quickly and is suitable for morning use under moisturiser and SPF. The serum is clinically proven to help reduce the appearance of wrinkles and hyperpigmentation in just 4 weeks. Due to its lipid base, the formula is not the best choice for oily skin.
