Medik8 C Tetra Luxe is Medik8’s top Vitamin C serum, containing twice as much C as the its regular C serum.

This enhanced radiance serum has been developed in water-free base to enable it to deeply penetrate the skin.

It will deliver superior antioxidant protection and anti-ageing benefits while being gentle on the skin.

Why Medik8 C Tetra Luxe?

Medik8 C Tetra Luxe fends off environmental damage and activates the skin’s repair response, thereby fending off premature skin ageing.

Medik8 C Tetra Luxe uses an advanced form of Vitamin C at a concentration of 14%. In addition, it contains another great antioxidant, Vitamin E, which works synergistically with the Vitamin C and enhances its effectiveness.

These two antioxidants work together to defend the skin against free radicals from the environment.

Vitamin C is one of the most powerful skin-firming and skin-brightening ingredients, however Vitamin C needs to be able to penetrate to work its magic.

For this reason, Medik8 uses a lipid-soluble base of Squalane, Jojoba and Maracuja oils. These are dry oils that are easily absorbed by the skin. These also leave the skin feeling silky soft and give it an enhanced glow.

Medik8 C Tetra Luxe ingredients

The key ingredients are:

Tetrahexyldecyl Ascorbate is a form of Vitamin C that’s a stabilised version of the famous L’Ascorbic Acid, the purest form of Vitamin C. It’s an effective but more gentle form of this superhero ingredient. Medik8 has doubled up on the level of Tetrahexyldecyl Ascorbate found in the original Medik8 C Tetra for improved results.

Vitamin E protects the skin from free radical damage and enhances the effectiveness of the Vitamin C by regenerating its antioxidant powers.

Red Ginseng Root Oil energises and brightens the skin so that it looks firmer and more even toned. This traditional botanical is a potent tyrosinase inhibitor, meaning it helps reduce the formation of discolourations.

Maracuja Oil, extracted from passionfruit seeds, is a luxurious oil that’s rich in Vitamin E and Linoleic Acid, which has nourishing and protective properties. This superfruit oil promotes a firmer and more radiant complexion.

Squalane and Jojoba nourish and moisturise, helping restore the skin barrier, while also facilitating penetration of the actives.

Medik C Tetra Luxe review

Within a week of using Medik8 C Tetra Serum, I noticed my skin becoming brighter. My skin has a lovely glow that makes it look healthy. I can’t say that I’ve seen any reduction in fine lines, but then this serum is preventative. You use it to prevent wrinkles from creeping up on your face, not so much to reduce those that are already there. And the science there is solid. Vitamins C and E can destroy free radicals before they leave wrinkles on your face. So I have no complaints here. I know that my skin is well protected all day long.
