    Medik8 C-Tetra® is a revolutionary ultra-stable vitamin C serum which helps combat sun-induced damage to the skin, trigger collagen synthesis, increase the skin’s elasticity and density as well as improve the skin’s texture and brighten the complexion.
    Designed for both men and women in their mid-20s to 30s.

    Regular vitamin C is very unstable and many typical vitamin C products are inactive by the time they are used on the skin, in some cases, they have become pro-oxidant and actually generate free radicals! Ground-breaking stability data on C-Tetra guarantees real vitamin C activity and best of all, unlike L-ascorbic acid (regular vitamin C), C-Tetra will not exfoliate or irritate skin.

    C-Tetra® contains 3% Tetrahexyldecyl Ascorabte, the most potent and highly stable derivative of vitamin C available.
    C-Tetra has been shown to have upto 4 times the potency L-ascorbic acid and other derivatives such as MAP (magnesium ascorbyl phosphate).
    d-Alpha Tocopherol (natural vitamin E) 1.0% - antioxidant, helps to protect skin from free radical damage and act as network antioxidant with vitamin C.

    Size: 30 ml, dropper bottle - up to 100 applications

    Medik8 C-Tetra Antioxidant Serum 30ml Review by customer
    I use the serum after I gently wash my face. I place one drop each on my forehead & both cheeks & I rub it in. I tried putting it on my hands first before applying on my but the product absorbed a bit in my hands before I could get it to my face. So applying directly to my face is more efficient. It's light & absorbs quickly. After applying I use a moisturiser as I get a bit of dry skin using it alone. My skin is much brighter & even though I'm not a heavy makeup user I can go out with just an SPF primer applied to my skin & it looks great. Definitely recommend for those who's looking to brighten their complexion. (Posted on 30/06/2014)

    Miracle8! Review by jo
    I bought Medic8 products from Dermacare Direct mainly because of the brilliant videos with the nurse talking about how to use them. It saved me a £30 consultation with a therapist which was my other option if I wanted to buy them from a clinic. They came fast which is unusual for free delivery and I have been literally blown away by the results. I have had chronic acne for 26 years and became a nutritionist whilst searching for a way to heal my skin from the inside. Having worked on this for 6 years without results I resorted to products to see if I could support the structure of my skin externally. One week later my skin is almost clear - I am so happy. Anyone with acne knows how debilitating it is and particularly so for a therapist! I think medic8 should be renamed Miracle8! If anyone is interested in what combination I used it is the following:- Betacleanse, Betagel, Retinol, C Tetra, Hydr8 B5, Hydr8 Beta. (Posted on 14/09/2012)
