A real shock treatment to boost hydration, Sérum Yall~02 contains ultra-high doses of hyaluronic acid and antioxidant plant extracts. This intense hydrating treatment provides the amount of moisture skin needs to function properly and feel comfortable. The effect is instant, as the fine lines caused by dehydration are plumped up.
Apply 4 to 5 drops of finishing serum to the entire face, neck and décolleté, in the morning and/or at night. This product is applied as the final touch of the Biologique Recherche skincare program.
"My bank account will hate me for saying this but this is THE BEST finishing serum out there - it is even better than la grand one!! Nourishing, moisturizing, beautifying, glow-adding!!!!! The best!!! Treat yourself and get it!!! Works best with my creme amnios and vg derm, too much with vernix and sticky on the top of dermopurifiante"
