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. As a lipid-soluble form of vitamin C, it is able to penetrate the skin’s defensive lipid barrier with ease; delivering benefits deep within the skin. 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.

Medik8 - Love It

I found Medik8 a number of years ago and haven’t looked back since. Noticed a difference straight away, and have refined my regimen for my mature skin.

Great product!

I pair this product with the C-Tetra Eye serum and they work so beautifully together.

Super easy to apply and leaves my skin feeling so nourished.

I highly recommend adding this product into your daily routine.

I’ve seen great results so far just with helping reduce the pigmentation and dark circles on my face.

I’m 26 and have been dead long with pigmentation for a while and nothing has really helped until I found this product.
