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: 8 ml

After cleansing in the morning, massage 6 drops of C-Tetra Luxe across the face, neck and décolletage. Leave to absorb before applying sunscreen. We recommend Advanced Day Total Protect.
