Serum YALL~O₂
Stimulates the fullness of skin and lips
Serum Yall O2 is a deeply hydrating finishing serum that acts as an intense moisture surge to instantly rebalance, plump, and smooth the complexion. Formulated with ultra‑high doses of both high‑ and low‑molecular‑weight hyaluronic acid to support hydration at multiple depths within the epidermis, this serum significantly improves skin moisture retention and helps reduce the appearance of fine lines caused by dehydration while protecting against transepidermal water loss. A concentrated kale‑derived plant extract delivers antioxidant support, helping to combat environmental aggressors that can accelerate signs of aging, while other botanical ingredients work to nourish and enhance overall skin comfort and suppleness. Designed to fortify the skin’s hydrolipidic film and increase elasticity
Apply a few drops of Sérum Yall ~ O2 to the eyes contour, the whole face, neck, cleavage, and lips in the morning and/or evening. This product is applied as the finishing touch to your Biologique Recherche skin care program.
