- Pro-ingredient - Triple vitamin C is a composition of three very stable forms of vitamin C, which complement each other and enhance their effects on the skin. Especially in its deeper layers, where they particularly stimulate collagen and elastin production and fight free radicals: * 1.5% Vitamin C Tetra E (ascorbyl tetraisopalmitate) is a fat-soluble vitamin C derivative. Has an anti-ageing and antioxidant effect. Protects against skin ageing caused by UV radiation. Stimulates collagen and elastin production and evens out skin tone. * 1.5% 3-O-Ethyl Ascorbic Acid is a water-soluble vitamin C derivative. It penetrates deep into the skin, where it is metabolised to ascorbic acid. This has a dual effect on collagen - repairing its structure on the one hand and increasing its synthesis on the other. * 0.5% Superox C-AF, an extract from the cockatoo plum, which contains the highest amount of vitamin C in the world. It enhances cellular defence against free radicals, stimulates the synthesis of procollagen and hyaluronic acid. It smooths wrinkles and prevents the appearance of new ones. - Cottonseed oil nourishes, regenerates, moisturises and softens. It also replenishes lipid deficiencies in the skin, strengthening the hydrolipid barrier and promoting water retention in the epidermis. Similarly, mango butter - moisturises, softens the skin and forms a film on the skin that retards water evaporation. - Carotenoids from Dunaliella salina algae extract and sea buckthorn oil, as well as vitamin E, fight free radicals and inhibit the skin's ageing processes caused, among other things, by UV radiation. In addition, they regenerate the skin and strengthen the epidermal barrier, limiting water loss.
