Sérum Yall~O2 - Hydration Plumping Serum | Biologique Recherche

Hydration shock elixir
Recommended for dehydrated skin

BENEFITS: MOISTURIZING / SMOOTHING / PLUMPING

Sérum Yall~O2 delivers a dual hit of high- and low-molecular-weight hyaluronic acid combined with a kale-derived concentrate to flood skin with lasting hydration at every layer. Skin feels visibly suppler and plumper, fine lines appear smoothed, and the complexion looks more comfortable and rested — with moisture levels proven to remain elevated for several hours after application.

Application note: Unlike most serums, Sérum Yall~O2 is applied at the end of your skincare routine — after your moisturizer — or directly before foundation.
