The Bioderma Hydrabio Hyalu Plumping Hydrating Serum is uniquely formulated for dehydrated skin to hydrate, plump, and enhance radiance. This powerful serum harnesses a blend of low and high-molecular-weight hyaluronic acids to deeply hydrate from within and form a protective barrier on the skin's surface, effectively combating transepidermal water loss. Enriched with Carnosine's antioxidant properties and strengthened by Niacinamide to bolster the skin barrier, it not only hydrates but also defends against oxidative stress, preserving the skin's natural hyaluronic acid and collagen. Following BIODERMA's ecobiological approach, this serum integrates biomimetic active ingredients, ensuring natural compatibility with the skin, leading to a supple, radiant complexion. Plus, its light, hypoallergenic fragrance, rigorously tested to be safe for sensitive skin, enhances the sensory experience, making your skincare routine both effective and enjoyable.

Key ingredients in the Bioderma Hydrabio Hyalu Plumping Hydrating Serum with Hyaluronic Acid 

Multiple weights of Hyaluronic Acid
The smaller size of low-molecular-weight hyaluronic acid penetrates deeper into the skin to where it is most needed to hydrate from the inside, promote natural rehydration and plump fine lines. 
The larger size of high-molecular-weight hyaluronic acid forms a protective barrier on the surface of the skin to hydrate from the outside and prevent transepidermal water loss.
Carnosine 
Carnosine uses antioxidant power to protect against oxidative stress. Oxidative stress contributes to the degradation of the skin's natural hyaluronic acid and collagen.
Niacinamide 
Supports the skin barrier by promoting lipid production to prevent transepidermal water loss.
