How It Works
Your skin contains natural antioxidants that work to defend against free radicals from the environment. When these environmental free radicals outweigh your skin’s antioxidants, the skin can no longer protect itself. Free radicals latch onto the defenceless skin cells, causing irreparable damage, which ultimately leads to premature skin ageing.
C-Tetra Luxe offers optimum skin protection from free radical damage, featuring elevated levels of vitamin C to boost the natural antioxidant defence levels in the skin. Vitamin C is a key pillar of our CSA Philosophy, due to being one of the most powerful vitamins for preventing the signs of premature skin ageing. Vitamin C also helps to stimulate collagen production, and can disrupt the overproduction of melanin to brighten the appearance of dark spots and uneven skin tone. The result? Visibly radiant, healthier, more youthful-looking skin. C-Tetra contains an enhanced level of tetrahexyldecyl ascorbate, a form of vitamin C which is a stabilised modification of ascorbic acid (the purest form of vitamin C) that is gentle on the skin yet proven to deliver visible results. C-Tetra Luxe has double the level of tetrahexyldecyl ascorbate found in the original C-Tetra serum, for improved visible results.
Infused with Amazonian maracuja oil, C-Tetra Luxe is powered by the exotic antioxidant properties that originate from the passion fruit. Sustainably-sourced, our maracuja oil is naturally rich in vitamin E and linoleic acid, renowned for its nourishing and protective qualities on the skin. The superfruit helps to leave skin looking firmer and smoother with a noticeable glow.
The intense brightening power of C-Tetra Luxe is supercharged with the influence of optimised red ginseng. With incredible abilities as a potent tyrosinase-inhibitor, the botanical component works with vitamin C to restore the appearance of skin’s natural radiant, even tone.
All of the above technologies are delivered with ease in a silky squalane-base combined with vitamin F to envelope the complexion in total nourishment that feels rich with moisture all day long, while helping to nurture the skin's natural barrier.
How To Use
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.
Patch testing prior to use is advised. Refer to medik8.co/patch for an in-depth guide to patch testing.
