Collagène Originel serum targets the four main types of collagen to enhance skin density in three dimensions. Featuring a unique blend of four active ingredients, it boosts the production of type I and III collagen, which are the most prevalent in the skin, as well as types IV and VII to improve the structure of the dermal-epidermal junction, thereby significantly minimizing the appearance of wrinkles. For the first time in cosmetics, it includes Type-0 Collagen©, a patented active ingredient by Biologique Recherche. Known as “type 0,” this collagen is the progenitor of all collagen types and exhibits specific affinities with various collagen forms. It particularly enhances the production of collagen VII to facilitate the interactions between the dermis and the epidermis, which tend to diminish with age.
