Formulated with nourishing, pampering oils combined with the anti-ageing power of vitamin C, this fast-absorbing vitamin C serum is ideal for those looking for skin rejuvenation. Perfect for those who are new to vitamin C, or are looking to upgrade from C-Tetra Cream or Daily Radiance Vitamin C.
Carefully crafted in a water-free formula to be 100% stable, the vitamin C does not degrade over time. This ensures that your formula remains highly potent from the very first use to the final drop.
Harnessing the power of Medik8’s best-selling vitamin C serum ( C-Tetra), C-Tetra Intense is boosted with additional brightening and nourishing ingredients, listed below.
How It Works
Your skin is packed full of natural antioxidants that 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 ageing.
C-Tetra contains Tetrahexyldecyl ascorbate, a super-stable form of vitamin C that boosts the antioxidant defence levels in the skin. Ever the multi-tasker, it also stimulates collagen production to reduce the appearance of fine lines and wrinkles, leaving the complexion plump, radiant and youthful looking.
Vitamin C and vitamin E work together synergistically as 'network antioxidants', boosting the serum’s overall antioxidant effect to keep skin protected throughout the day.
C-Tetra® Intense - Packed full of nourishing vitamin F and squalane which help to reinforce the skin’s natural protective barrier against free radicals.
C-Tetra® Intense - Red ginseng boosts the serum’s brightening powers for a luminous, even complexion.

The Science Behind
“It is exceptionally difficult to formulate a long-lasting vitamin C serum that will keep its power over time. It is notoriously unstable, sensitive to oxidation and can often turn yellow in colour, which indicates that it has gone off. Medik8’s C-Tetra range utilises an extremely stable form of vitamin C, called tetrahexyldecyl ascorbate. This molecule is altered to make it less reactive to oxidation, meaning that even 6 months down the line you can be sure your vitamin C is still as potent as when you first opened it.”
