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.

Dermatologist review

I am a dermatologist and am looking into new products to stock and sell in my clinic, I have recently purchased C-Tetra and am currently using in as a serum, 1 application daily in the morning underneath my day cream and sunscreen.

Medik 8 is well know for delivering products with a strong pipe line of well calculated actives.

Though this brand is a high end skin care brand they do use the money your paying for to deliver a high standard of dermatological active ingredients as to wasting money on beautiful packaging like other high end brands like la prairie.

C-Tetra is a very well delivered, formulated, well tolerated vitiman C serum.

Many people, especially younger patients of mine do not want to use any products that may bring about the reality that they are putting oil on their ski , as they thread oil to the conclusion of clogged pours and pimples.

This is how ever not the case from a scientific perspective when it comes to skin care.

An oil or a serum has a mechanism allowing it to be semi- permeable through the skin cells allowing for better penetration and absorption.

Creams sit on the surface of the skin and are unable to penetration through the superficial layers (epidermis) of the skin resulting in a lack of ability to do their job- no matter how good the product is.

C-Tetra because of its consistency allows for substantial penetration into the epidermis and dermis which inturn results in results on the inside and outside of your skin.
