Previously known as the C-Tetra Intense, the hard-working C-Tetra Luxe 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.

After cleansing in the morning, massage 4 drops across the face, neck and décolletage. Leave to absorb before applying further products.

Please note: the visual and product name listed may differ to the packaging received due to product updates across the range. Rest assured, the formula and great results will remain the same.
