Medik8 C-Tetra Advanced Serum

Defend against premature skin ageing and achieve accelerated skin brightening with a next-generation combination of 20% vitamin C and skin barrier science. 

Clinically proven to brighten skin and visibly improve wrinkles in 7 days with 0% barrier disruption, C-Tetra Advanced is engineered for high-performance visible brightening, skin smoothing, and daily antioxidant defence. 

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 aging 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.
• Multi-Weight 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.

The result? A high-performance, age-defying vitamin C serum that works smarter, not harsher.
