C-Tetra EF
Intensive Vitamin C treatment with a powerful antioxidant effect designed to offer optimal protection against free radicals, helping to recover luminosity and combat photoaging for brighter, firmer and smoother skin.
In this formula you will find three different types of vitamin C. Why? Very simply, the function of vitamin C in each layer of the skin is different, and for its benefit to be maximum it is necessary to combine different types to get the most out of it.
Among the many types of vitamin C that exist on the market, we have selected the most stable and pure ones so that this formula is effective in all layers of the skin where it can be beneficial. We explain their differences:
Formulated with 10% Tetra Vitamin C, highly biocompatible and fat-soluble. The fact that it is fat-soluble allows this vitamin to be transported to the deepest layers of the skin. Here its action focuses on melanocytes (to treat spots from the inside) and on collagen synthesis, to prevent and combat wrinkles from the inside. Its formula is complemented by Ascorbosilane and Ascorbyl Glucoside, two other derivatives of Vitamin C, very stable and water-soluble. These act on the surface of the skin, improving luminosity and fading the most superficial spots.
Finally, Vitamin E and Ferulic Acid help enhance the antioxidant effect of the serum to keep the skin protected throughout the day.
