  • Amazing product that makes your skin look and feel great!
Size: 1.01 Fl Oz (Pack of 1)
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. ... show more

  • Just what my skin needed in my 30s!”
Size: 1.01 Fl Oz (Pack of 1)
I’m in my 30s and recently started noticing the first signs of tired, dry skin. La Roche-Posay’s Hyalu B5 Serum has truly made a difference — it deeply hydrates, improves elasticity, and leaves my skin looking fresher and more radiant. It’s gentle, non-irritating, and absorbs quickly. Perfect for anyone looking for an effective anti-aging serum without the fuss. Highly recommended! ... show more

  • Love this hyaluronic acid serum!
Size: 1.01 Fl Oz (Pack of 1)
This serum is hydrating, lightweight, and soothing. I use it before my moisturizer and my skin feels plump and refreshed. It absorbs quickly and doesn’t feel sticky — I love it!

  • Lightweight Serum, Heavyweight Results
Size: 1.01 Fl Oz (Pack of 1)
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!" ... show more

  • Fantastic!
Size: 1.01 Fl Oz (Pack of 1)
Great product! My skin looks and feels more youthful after using this product for only a few days. I purchased for the fist time a few months ago and it is now my favorite product in my skin care regimen. If your face feels sticky then you are using too much. The "perfume" smell goes away after an hour or so. It's great for men and women. You really only need to use it once per day. Too much and it could cause breakouts. ... show more

  • Improves skin texture and glow
Size: 1.01 Fl Oz (Pack of 1)
This product is well worth the money. The result is smooth, younger looking, glowing skin. Several people asked if I had a facial or other procedure recently. It isn’t oily and didn’t cause any irritation. It does have a fragrance that took some getting used to as I typically use products that are fragrance free, but it was unnoticeable after a few applications. Highly recommend! ... show more

This serum has been a lifesaver for my dry skin. I use it every morning before my moisturizer and have noticed a huge difference in the elasticity and smoothness of my face.
