Medik8 – C-Tetra® Luxe is an advanced version of the iconic vitamin C serum designed to deliver instant radiance and skin revitalization. The formula with 14% tetrahexyldecyl ascorbate – a stable, lipid-soluble form of vitamin C – provides twice the antioxidant protection compared to the original C-Tetra. From the very first use, the skin appears smoother, more even-toned, and visibly brighter.

Enriched with red ginseng extract, the serum boosts skin regeneration and enhances a youthful glow. The combination of vitamins C and E defends against oxidative stress, while squalane and vitamin F deeply nourish and restore the lipid barrier, preventing moisture loss. The silky, fast-absorbing texture makes it ideal for daily morning use under moisturizer or SPF.

Size: 30 ml

After morning cleansing, apply 4–5 drops to the face, neck, and décolletage, gently massaging until fully absorbed. Allow the serum to absorb completely before applying sunscreen. Recommended for use with Advanced Day Total Protect.
