Bioderma Hydrabio Serum

Hyaluronic Hydrating Serum for Dehydrated, Sensitive Skin

Bioderma Hydrabio Serum is a lightweight daily booster that floods dehydrated, sensitive skin with hydration and helps lock it in. It pairs hyaluronic acid for an instant plumping feel with Bioderma's patented Aquagenium hydration technology, which supports the skin's own water balance for lasting comfort.

Why Choose It?

• Instant plumping hydration: Hyaluronic acid binds water at the surface for a smoother, fresher feel from the first use.
• Lasting moisture balance: Aquagenium hydration technology helps skin reactivate its own water-handling for longer-lasting comfort.
• Barrier support: Niacinamide helps strengthen the skin barrier and calm everyday sensitivity.
• Silky, layer-friendly finish: Lightweight gel-fluid texture absorbs fast and sits cleanly under moisturizer, makeup or SPF.

Best For

Dehydrated, sensitive skin that feels tight, dull or thirsty and needs a lightweight daily hydration step before moisturizer. Comfortable under makeup or SPF in the morning and under a richer cream at night.

Use morning and evening as the hydration step before moisturizer. Follow with a face cream for dehydrated skin to seal in the hydration.

• Apply to clean, towel-dry face and neck after cleansing and any toner step.
• Dispense one to two pumps onto the fingertips.
• Press and smooth gently over the face and neck — the gel-fluid absorbs on its own.
• Allow about a minute for the serum to settle before the next step.
• Follow with a daily moisturizer and, in the morning, sunscreen.

Tips

• Can be used alone in warmer weather when skin only needs a lightweight hydration layer.
• Layers cleanly under makeup or SPF in the morning routine.
• If skin is reactive or you are layering multiple actives, patch test on the inner forearm before first full-face use.
