❓ Frequently Asked Questions
How is this different from drugstore hyaluronic acid serums?
La Roche-Posay uses TWO molecular weights of hyaluronic acid (high and low) for multi-depth hydration, plus madecassoside for soothing - ingredients not found in most drugstore options. It's also formulated with French thermal spring water and undergoes rigorous dermatological testing for sensitive skin.
Is $40 worth it compared to $15 CeraVe or $6 The Ordinary?
If you have sensitive or mature skin, yes! The dual-weight HA and madecassoside offer superior plumping and soothing. However, if you're under 30 with normal skin, you might be fine with budget options. Many users find La Roche-Posay absorbs faster and layers better under makeup.
Can I use this if I'm already using retinol?
Absolutely! This serum is PERFECT with retinol. Apply Hyalu B5 first, let it absorb, then apply retinol. The vitamin B5 and madecassoside help buffer retinol irritation while the HA enhances penetration for better results with less sensitivity.
Will this help with deep wrinkles or only fine lines?
It's most effective on fine lines and early wrinkles (crow's feet, forehead lines, smile lines). For deep-set wrinkles, combine this with retinol, vitamin C, or consider professional treatments. HA plumps but doesn't restructure deeply damaged skin.
My skin feels sticky after applying - what am I doing wrong?
You're using too much! Start with just 2-3 drops for your entire face and neck. Press it in rather than rubbing. If still sticky, your skin might be producing enough hyaluronic acid naturally - try every other day instead of daily.
Can I use this if I live in a dry climate?
Yes, BUT you MUST seal it with a moisturizer immediately! In low-humidity environments, HA can actually pull moisture FROM your skin if not sealed properly. Apply to damp skin, then lock it in with moisturizer within 60 seconds.
How long does one bottle last?
With twice-daily use (2-3 drops each time), expect 6-8 weeks. While expensive per ounce, you need very little product. Many users alternate with cheaper HA serums to make it last longer while still getting the benefits.
Is this safe during pregnancy?
Yes! Hyaluronic acid, vitamin B5, and madecassoside are all pregnancy-safe ingredients. However, always consult your healthcare provider before starting new skincare products during pregnancy.

ℹ️ About This Product
La Roche-Posay is the #1 dermatologist-recommended brand in Europe and specializes in sensitive skin formulations. Their Hyalu B5 line was developed specifically for aging skin that's also sensitive, a combination often neglected by other brands. The inclusion of madecassoside (a Centella Asiatica derivative) is what sets this apart from other HA serums - it actively calms inflammation while the HA plumps.
