LIERAC Lift Integral The Regenerating Night Cream reinforces the skin's structure by acting on its essential elements (collagen, elastin, hyaluronic acid), but also on the glycoproteins that connect them. The skin regains firmness, elasticity and bounce, for a complete lifting effect. The unctuous and ultra-enveloping texture of La Crème Nuit Régénérante intensely nourishes the skin without an oily finish. For the first time, LIERAC Research decodes the ultimate secret of the structure of the skin. The skin needs collagen, elastin, hyaluronic acid, but not only. At the heart of the new Lift Integral, the StructureLift complex acts on these 3 essential elements, but also on the glycoproteins. Capable of connecting these elements together, they restore the structure of the skin. Rose RNA stimulates the natural synthesis of collagen and its associated glycoprotein, fibronectin. This 100% natural ingredient comes from the Grasse rose, grown without pesticides. Black Tulip stimulates the natural synthesis of elastin and its associated glycoprotein, fibrillin. Formulated to suit all skin types, even sensitive. 98% of natural origin ingredients. Vegan. Dermatologically tested.
