Bioderma Hydrabio Serum is a hydrating concentrate that delivers both instant and long-lasting moisture to the skin. Its formula, enriched with the Aquagenium™ patent and key hydrating ingredients like Hyaluronic Acid, Xylitol, and Glycerin, works to replenish the skin’s water reserves and activate its natural rehydration mechanisms. This face serum not only provides immediate hydration but also stimulates the production of aquaporins, which help retain and circulate moisture within the skin for lasting results. The result is smooth, radiant skin with a fresh, non-greasy texture that also makes it an excellent base for makeup. It has very good tolerance and is non-comedogenic.
