Hydrabio Sérum is a hydrating serum for all skin types, whether oily, sensitive, dry, normal or combination. Dehydration (when the skin lacks water) is a temporary state that can affect anyone at any age. Dehydrated skin is not a skin type or specific to one skin type. It most frequently affects the face.
Hydrabio Sérum is formulated with targeted active ingredients to maximize efficiency on application and over time. Immediate hydration: 2 x more high molecular weight hyaluronic acid (1) and 1.5 x more glycerin (2) to capture water and prevent water loss. Patented Aquagenium+ Technology immediately helps the skin reactivate its natural moisturizing mechanisms by stimulating water circulation. Lasting hydration: niacinamide helps the skin synthesize its own lipids to strengthen its barrier function, while prebiotic sugar contributes to a healthy, diverse microbiome—which is essential for healthy, balanced skin.
