About the product
Sérum Yall~O2 is the radiance serum. It combines Biologique Recherche's own oxygenating complex with hyaluronic acid, marine collagen and pomegranate, hibiscus and lily extracts. The idea is simple: hydrate the skin and help it breathe better, especially in the city.
The texture is silky and very pleasant, melts in within seconds and leaves a fresh, shine-free finish. You notice it in the tone: the grey cast of tiredness, pollution or too little sleep gives way to colour and freshness.
It is a finishing serum that gets along with everything, and one of our favourites for urban skin.
