Medik8 C-Tetra LUXE Serum 30ml


Previously known as the C-Tetra Intense, the hard-working Medik8 C-Tetra Luxe Serum uses vitamins C and E to intelligently combat sun and pollution-induced damage together.

Name a more iconic duo, we’ll wait – the two vitamins work in synergy to encourage each other’s effects, resulting in an antioxidant-rich formula that doesn’t lose its potency over time.

Lightweight and fast-absorbing, the clever formula stimulates collagen and elastin production to help diminish the look of fine lines and wrinkles, all while brightening and balancing skin for a more radiant and youthful complexion.

The vitamin C works deep within the skin – thanks to its lipid-soluble form that allows it to pass through the skin’s defense barrier – giving you greater antioxidant protection with less irritation.

The more antioxidants on the skin, the better protection against free radicals – look at antioxidants as little force fields that protect your delicate epidermis.

Teaming with nourishing oils, fatty acids and squalene, the C-Tetra Luxe is perfect for reinforcing the skin’s protective barrier, age-defying and hydrating – leaving you smooth and glowy. Complemented by a fresh, natural, citrusy scent and with brightness properties that are magnified by maracuja oil and red ginseng, the C-Tetra Luxe is a morning must-have.

Each morning after cleansing, massage a few drops into the face and neck. Ensure the product is fully absorbed before moisturising.

This lightweight vitamin C serum stimulates the production of collagen and elastin, to diminish the appearance of fine lines and wrinkles. Vitamins C and E provide powerful antioxidant protection, to combat both sun and pollution-induced damage.

C-Tetra’s water-free formula is 100% stable, ensuring the Vitamin C within does not degrade over time. Suitable for first-time vitamin C users.


After cleansing in the morning, massage 6 drops of C-Tetra Luxe across the face, neck and décolletage.

Leave to absorb before applying sunscreen. We recommend Advanced Day Total Protect.
