Medik8 C-Tetra is a lightweight, non-irritating vitamin C serum formulated with 7% tetrahexyldecyl ascorbate, a stabilised, lipid-soluble form of vitamin C that penetrates deeply to brighten, smooth and protect the skin. Enriched with vitamin E for added antioxidant defence, this fast-absorbing serum helps to combat free radical damage, even out skin tone and promote a healthy glow—all without irritation. Perfect for first-time vitamin C users or those with sensitive skin.
With once-daily use, a 30ml bottle lasts approximately 8–10 weeks, making it ideal for consistent, subscription-based routines.
