Your skin loses 25% of its hyaluronic acid reserves by age 40, leaving you with dehydration lines that makeup settles into. La Roche-Posay Hyalu B5 Water Gel delivers dual-weight hyaluronic acid plus mattifying airlicium to plump your surface and smooth your texture without shine.
Key Benefits
- Dual hyaluronic plumping: Two molecular weights hydrate your top layer and deeper skin at once for all-day bounce
- Mattifies while hydrating: Airlicium absorbs oil so you stay shine-free under makeup or SPF
- Smooths dehydration lines: Salicylic acid gently exfoliates dead cells so fine lines look less visible within days
- Repairs overnight barrier: Vitamin B5 soothes irritation and locks in moisture while you sleep
- Instantly absorbed gel texture: Zero grease, zero residue, layerable under every moisturizer and sunscreen
Key Ingredients
Dual Hyaluronic Acid: Two molecular weights deliver surface hydration and deeper plumping to smooth dehydration lines. Vitamin B5 (Panthenol): Repairs your moisture barrier and calms redness overnight. Salicylic Acid: Gently exfoliates dead cells so your skin texture looks smoother and absorbs hydration better. Airlicium: Mattifying micro-powder absorbs excess oil for a shine-free finish all day. La Roche-Posay Thermal Spring Water: Selenium-rich mineral water soothes sensitivity and reinforces your skin's natural defenses.
How to Use
Apply 2 to 3 drops to clean, dry skin every morning and evening. Press gently into your face and neck. Do not rub. Pressing maximizes absorption. Follow immediately with your moisturizer. For extra overnight repair, layer a second application under your night cream. Compatible with all retinoids, acids, and SPF.
