All BIODERMA products are formulated according to the ecobiology principles, which is at the heart of NAOS approach to respect the skin's ecosystem and preserve its health in a lasting way.
Inspired by the pioneering NAOS approach of ecobiology, and thanks to its understanding of the biological dysfunction responsible for dehydration, Hydrabio Hyalu serum empowers the skin to reactivate its natural hydration mechanisms and retain the water essential to its balance.

The complementary action of rightly dosed active ingredients: biomimetic low molecular weight (LMW) Hyaluronic Acid, Niacinamide, Carnosine and the Hyalu Technology (combination of biomimetic, high molecular weight (HMW) Hyaluronic Acid and a self-rehydrating sugar) act on the internal causes of dehydration and the visible signs of aging, to provide lasting effectiveness.

•An immediate moisturising and plumping action: HMW Hyaluronic Acid which creates a film on the surface, preventing the water loss, plus a new self-rehydrating sugar that helps skin synthetize and preserve Hyaluronic Acid.

•A toning action using LMW Hyaluronic Acid, which helps to stimulate collagen to gain in fimness and elasticity.

•A strengthening action using Niacinamide, which consolidates the barrier function to reduce dehydration.
