Medik8 C-Tetra Luxe is a high-performance vitamin C serum designed to visibly brighten, smooth and nourish the skin while delivering advanced antioxidant protection. Clinically proven to reduce the appearance of fine lines and pigmentation in just four weeks, the luxe formula enhances overall radiance while supporting the skin barrier.

Formulated with 14% tetrahexyldecyl ascorbate, a stabilised and oil-soluble form of vitamin C, the serum delivers powerful results with a gentle, non-irritating experience. The velvety, oil-based texture deeply hydrates and softens the skin, making it ideal for those seeking both glow and comfort. Enriched with squalane, jojoba oil and botanical oils, C-Tetra Luxe helps minimise dryness while promoting a smoother, more youthful-looking complexion.
