Restore the comfort & radiance of your dehydrated skin with the gentle Bioderma Hydrabio Mask. This weekly mask contains Bioderma's patented Aquagenium® biological complex to stimulate in-depth moisture & lock it on to the skin's surface. From the first use, it provides deep down, lasting moisture, even during periods of extreme dehydration. Over time, the Hydrabio Mask allows the skin to regain its softness, suppleness & radiance. The smooth, wrapping texture of the cream provides a feeling of pure pleasure. Apply a thick layer of the Hydrabio Mask over the face & neck, leave for 10 minutes & remove the excess with a cotton pad. For optimum results, use the Hydrabio Mask every day for the first week, & once weekly after that. The Bioderma Hydrabio H2O Micelle Water is hypoallergenic & non-comedogenic.
