Sérum Yall-O2 by Biologique Recherche is an advanced finishing serum designed to visibly plump, hydrate, and smooth the skin. Infused with oxygenating actives and high molecular weight hyaluronic acid, it restores volume to hollow areas, softens fine lines, and gives the complexion a refreshed, youthful glow—making it ideal for mature or dehydrated skin.
Sérum Yall-O2 targets areas where volume is lost—cheeks, eye contour, lips—bringing hydration and bounce back to the skin. It supports elasticity and enhances skin’s oxygenation, giving a visibly smoother, fuller, and more vibrant appearance with each use.
This high-performance serum offers both immediate glow and long-term plumping benefits. It’s perfect for dull, dry, or aging skin that has lost firmness or looks tired—especially in harsh climates or during seasonal changes.
Skin looks immediately plumper, more luminous, and youthful. With consistent use, the appearance of fine lines is reduced, hydration is improved, and facial contours appear more lifted and defined. A must-have for restoring glow and volume without invasive treatments.
Sérum Yall-O2 delivers a powerful blend of hydration, oxygenation, and plumping care—all in one elegant formula. Ideal as a final step or makeup primer, it leaves your skin radiant, smooth, and full of life.
Skin feels smoother, fuller, and more luminous. With regular use, Sérum Yall-O2 helps improve hydration, restore elasticity, and reduce the appearance of fine lines—making it an essential step in any high-performance, age-defying skincare routine.
