Hurry up, only 10 items left in stock.
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

How to Use
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.
Frequently Asked Questions
Frequently Asked Questions
Can I use this if I have oily skin?
Yes, the airlicium mattifying powder absorbs oil while dual hyaluronic acid hydrates, so your skin stays plump without shine. The gel texture absorbs in seconds and won't clog pores or trigger breakouts.
Do I still need moisturizer after this?
Yes, this is a hydrating serum, not a standalone moisturizer. Apply it first, then follow with your regular cream or lotion to seal in the hyaluronic plumping and prevent water loss throughout the day.
Will this work under makeup?
Yes, the ultralight gel absorbs instantly with zero residue or pilling. The mattifying finish actually helps makeup last longer by controlling midday shine, especially in your T-zone.
How long until I see plumping results?
Most users notice smoother dehydration lines within 3 to 5 days of twice-daily use. Full plumping and barrier repair results show after 2 weeks of consistent morning and evening application.
