A true innovation resulting from scientific research, the Collagène Originel serum acts on the 4 main types of collagen to redensify the skin in 3 dimensions. A unique combination of 4 active ingredients, it promotes the production of types I and III collagen, the most abundant in the skin, and types IV and VII to improve the appearance of the dermal-epidermal junction. It thus significantly reduces the length of wrinkles. A first in cosmetics, it contains at its core Type-0 Collagen©, a patented Biologique Recherche active ingredient. As “type 0”, this collagen is the mother of all collagens and has particular affinities with the different types of collagen. It acts in particular on the production of collagen VII to promote exchanges between the dermis and the epidermis, which tend to decrease with age.
