Hydrabio sErum: Hydration booster for radiant and healthy skin
How can you restore a radiant complexion and radiant skin? Skin hydration increases comfort and contributes to radiant skin. Moisturizing face serum is the star product in any skincare routine.
BIODERMA’s Hydrabio SErum is directly inspired by the 4 principles of ecobiology to give your skin a burst of hydration.
- Hydrabio SErum contains biomimetic ingredients such as hyaluronic acid and glycerin, in perfect affinity with the skin,
- Hydrabio SErum interacts with and optimizes the skin's natural hydration by boosting water reserves and their distribution to the heart of cells, and by reinforcing the barrier function and water retention in the skin,
The new formula for this water-based serum is based on powerful ingredients that hydrate the skin: 2X more concentrated in hyaluronic acid¹ and 1.5 X more concentrated in glycerin¹. It meets the needs of dehydrated skin to offer immediate comfort on application and for up to 72 hours of hydration.
