In skin care the role of vitamin C (L-Ascorbic Acid) has always been limited. There’s a reason for that: It’s not absorbed well, it’s instable and it’s irritating. New developments and new techniques have created the possibility to stabilize Vitamin C. The Vitamin C molecule has 4 groups, that make it instable. Medex has stabilized all those 4 groups, through which the complete value of Vitamin C, which is real big, comes into power. It’s to be used very broadly, for many/all skin types and skin problems. From skin ageing to hyperpigmentation and sensitive skin. Read the explanation and you’ll see, that this 4x stabilized Vitamin C is always, either the answer to the problem, or at least a good support for another chosen goal. 4 x stabilized Vitamin C by Medex has numerous active forces with varying goals:

1. The anti-ageing process is caught by the combination of 4 x stabilized Vitamin C and natural Vitamin E. In this manner an anti-oxidant couple is formed which is active by nature and which is able to avoid undesired (per)oxidation of skin lipids by UV radiation (which is the cause of cell ageing), through which the skin is protected against cell damage by UV-stress, as well UV-B as UV-A. In practise, this means that the skin stays young.
2. Another important property of 4 x stabilized Vitamin C is the stimulating effect on the collagen synthesis. For this aspect, the strongly raised skin penetration of 4 x stabilized Vitamin C plays a crucial role, since the deeply lying fibroblasts should be reached here. Through the strongly lipophilic properties of 4 x stabilized Vitamin C this is the case, not only because the synthesis of collagen is stimulated, but also because the breakdown of collagen is diminished (therefore killing two birds with one stone!).
3. The Vit. C Serum (30%) with 4 x stabilized Vitamin C is such a powerful and all-round remedy, that it can be used for various indications. The height of the Medex-dosage of 30% makes this possible, when you think about the fact, that the activity of 4 x stabilized Vitamin C is already starting from 8%. And nevertheless, this 30% is suited for the most sensitive skin, even for the treatment of it.
4. 4 x stabilized Vitamin C is even used very successfully as a “whitening” ingredient, since it reduces the production of the enzyme Tyrosinase drastically, with the result that pigment synthesis is minimalized / normalized. Therefore, 4 x stabilized Vitamin C takes care of a beautiful, even skin, free from age spots, after a course of weeks (The skin will need one or two renewing cycles, to get rid of the old pigment).
