Medik8 C-Tetra Luxe 30ml

Twice the vitamin C of the original C-Tetra, in a velvety serum built for radiance and nourishment at once. C-Tetra Luxe delivers 14% stabilised vitamin C to work on the appearance of wrinkles, dark spots and uneven tone.

Optimised red ginseng boosts the brightening effect and supports collagen, while squalane and maracuja oil deliver the barrier nourishment that higher-strength vitamin C formulas often lack. Vitamin E completes the antioxidant network.

That nourishing base is the difference between a high-strength vitamin C you can use daily and one that leaves skin tight. The texture is rich but absorbs cleanly.

It is the right step up if C-Tetra has worked for you and you want more, or if your main concern is dullness and uneven tone rather than sensitivity. If skin is reactive, stay with C-Tetra at 7%.

Apply four to six drops each morning to a cleansed face and neck, then moisturiser and SPF.

It is the vitamin C step in Medik8's CSA routine, worn each morning under Advanced Day Total Protect or Advanced Day Ultimate Protect, with a Crystal Retinal or Intelligent Retinol at night. Oxy-R Peptides can be added if pigmentation is stubborn.
