I’m on my second bottle of the La Roche-Posay Hyalu B5 Serum and I absolutely love it! I use it every night, and it leaves my skin feeling hydrated, plump, and glowing. The hyaluronic acid in this formula is amazing, it absorbs beautifully and gives my skin that dewy, healthy look I adore. This serum has become a staple in my nighttime routine, and I’ll definitely keep ordering it. It’s gentle, effective, and makes a real difference. Highly recommend!

After using this regularly (I now buy the larger size), this has become my non-negotiable morning serum. My friends in France have been raving about this for years, and I finally understand why - it's a staple in French skincare routines for good reason. What sets this apart is the intelligent dual-hyaluronic acid formulation: the low-molecular-weight HA penetrates deeper layers to plump from within, while the high-molecular-weight HA creates a moisture-locking barrier on the surface. It's this combination that gives you both immediate hydration and long-term skin resilience. Plus, the madecassoside provides anti-inflammatory benefits while the B5 supports skin barrier repair. No questioning the quality here; La Roche-Posay's pharmaceutical background shows in the formulation precision. The texture absorbs beautifully, leaving no sticky residue, making it perfect for use under makeup or sunscreen. Worth every penny for the ingredient quality and consistent results.

Hydrated, Glowing Skin in a Bottle! Lightweight, non-greasy, and super hydrating! This serum plumps my skin and gives it a healthy glow without irritation. Absorbs fast and works great under makeup. A little goes a long way—definitely a new skincare staple!

This is my daily go-to and I am a no-facial product kind of person! It is very light and smells amazing. My husband even loves the smell. A little goes a very long way as it is pretty thick. When I get a new bottle, I just use the liquid that has clung to the outside of the dropper rather than even doing any drops. It makes my old, tired, dry skin feel moisturized and happy. I use what’s left on my hands on my neck and sometimes back of my hands and have definitely seen improvement there too! I started using this brand’s moisturizer during the harsh New England winter and love that as well.

I’ve been using the La Roche-Posay Hyalu B5 Serum for over a year now, and it’s become a staple in my skincare routine! I even put in on Amazon subscription so don't have to worry about running out. The lightweight, non-sticky texture absorbs quickly, leaving my skin feeling plump and hydrated without any greasiness. I love how it smooths out fine lines around my eyes and makes my face look fresher overall—my skin feels so soft! It layers beautifully under moisturizer and sunscreen, too. The dropper makes it easy to apply just the right amount. My only slight issue is that the bottle is a bit small for the price, so I wish it lasted a little longer. Still, the results are fantastic, and I’d highly recommend it for anyone seeking a hydrating boost!"

Why didn’t anyone tell me about this sooner?! After I turned 50, I noticed my face losing fullness and starting to look tired. I’ve tried a few products, but nothing worked quite like this. Hyalu B5 made a difference almost instantly. My skin felt hydrated and looked visibly plumper within days. It absorbs quickly, feels lightweight, and doesn’t leave any greasy residue. Best of all—no irritation, just smooth, refreshed skin. If you’re starting to see signs of aging or just want to bring some bounce and life back to your face, this serum is a must-have. I’m seriously impressed and will definitely keep this in my routine.

Why did you pick this product vs others?: Have been using this serum for a few years now; does not cause black dots or breakouts, smells like clean heaven, and it has caused a change in my skin in a matter of weeks.
