Advanced vitamin C serum for visible brightening

Dramatic Skin Brightening | Premature Skin Ageing Defence | Lightweight Finish | Enhanced Skin Barrier Support | Smooth & Even Complexion

The next generation of C-Tetra: 20% stabilised vitamin C combined with phyto exosomes for accelerated brightening and daily environmental defence, in a gel-serum texture rather than an oil.

Phyto exosomes deliver proteins, lipids and messenger molecules into skin cells quickly and efficiently, supporting recovery from environmental exposure. Acetyl zingerone works as an omni-antioxidant alongside the vitamin C, while hyaluronic acid and N-acetyl glucosamine hydrate and refine the look of pores.

The exosome delivery is the step change here. It is what allows a 20% vitamin C to perform without the barrier disruption a concentration that high would normally bring.

The gel-serum texture absorbs fast and primes the skin, making it easy to wear under SPF and makeup - and a better fit than C-Tetra Luxe if your skin is oily or congestion-prone.

Apply each morning before moisturiser and sunscreen.

It is the vitamin C step in Medik8's CSA routine - vitamin C and sunscreen by day, vitamin A by night. Choose this over C-Tetra Luxe if you want high strength in a lighter texture.

KEY INGREDIENTS

20% Stabilised Vitamin C (Tetrahexyldecyl Ascorbate): A highly potent yet gentle form of vitamin C for dramatic skin brightening and powerful antioxidant protection against premature skin ageing.

Phyto Exosomes: Encapsulated by nature, our phyto exosomes intelligently deliver proteins, lipids, and messenger molecules to skin cells. Together, alongside our supercharged vitamin C, they help prevent & reduce premature skin ageing by supporting healthier-looking, more resilient skin.

Acetyl Zingerone: A super-antioxidant that works synergistically with vitamin C, enhancing its efficacy while neutralising ageing free radicals and shielding skin from environmental stressors.

Hyaluronic Acid: Draws moisture into the skin to instantly plump and deeply hydrate for a soft, supple complexion.

N-Acetyl Glucosamine (NAG): A barrier-supporting, gentle, skin-refiner that smooths the look of pores while helping to increase the skin's own natural hyaluronic acid levels over time.
