La Roche-Posay Hyalu B5 Water Gel Hydrating Serum

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
