Bioderma Hydrabio Serum is a moisturizing concentrate specifically formulated for dehydrated and sensitive skin. This lightweight serum helps restore skin's natural hydration mechanisms while providing intense moisture and radiance. This hydrating serum contains Bioderma's patented Aquagenium™ complex which helps train the skin to better retain moisture over time. The formula is gentle enough for sensitive skin while being effective at combating dehydration. For best results, apply morning and evening to clean face before moisturizer. The 40ml size makes it convenient for both travel and daily use. As this is a skincare/personal care product, key features have been omitted per guidelines.
