Sérum Yall O2

Biologique Recherche has developed Sérum Yall O2, a replenishing, antioxidant and protective care product for the face and lips. Designed for all Skin Instants©, Sérum Yall O2 has been specifically formulated to deeply moisturize the skin, giving it suppleness, protection and radiance.

Its innovative formulation using nanotechnologies and an oxygenation vector provides an intensive treatment with an immediate beauty effect which continues with each application. This replenishing, regenerating elixir is a major weapon in the fight against the passage of time. This shock treatment, with high doses of hyaluronic acid and antioxidant plant extracts, restructures and protects the epidermis.


Apply a few drops of Sérum Yall O2 onto the eye contour, the entire face, neck, décolleté and lips, in the morning and/or evening. This product is applied as the finishing touch to the Biologique Recherche skincare program.
