Medik8 C-Tetra Luxe Lipid Vitamin C Enhanced Radiance Serum
What Is Medik8 C-Tetra Luxe?
Medik8 C-Tetra Luxe is an advanced lipid-based vitamin C serum that delivers exceptional antioxidant protection, visible brightening, and deep nourishment to the skin. With a high-strength 14% concentration of stabilized vitamin C (tetrahexyldecyl ascorbate), it is the most potent formulation in Medik8’s C-Tetra range — clinically proven to reduce hyperpigmentation, smooth fine lines, and restore radiance within just 4 weeks.*
Luxuriously silky and fast-absorbing, this serum is ideal for those seeking elevated antioxidant defense, skin rejuvenation, and a more even, luminous complexion — all while supporting and strengthening the skin barrier.
Recommended for most skin types, including sensitive and dry, C-Tetra Luxe is the perfect next step for those already using vitamin C or beginning their CSA (Vitamin C + Sunscreen by day, Vitamin A by night) routine.
