Guests are saying
The La Roche-Posay Hyalu B5 Serum is a highly effective skincare product that delivers intense hydration and improves skin texture. Guests appreciate its lightweight formula, quick absorption, and the inclusion of hyaluronic acid and vitamin B5, which help plump and soothe the skin. While some guests noted a strong fragrance, many found it suitable for sensitive skin and praised its ability to alleviate dryness and enhance radiance. This serum has become a staple in many skincare routines.

Sticky
It feels sticky, I don’t know why. I use different products from this brand but do not like this one.

Lovely floral smell and hydrates
Day 2 of using the product and I just love it. It is a thicker serum that definitely hydrates without feeling sticky, It has a light floral smell that is just lovely.

Issues with Absorption and Layering
I found that this product did not really absorb into my skin. I attempted to use it during both my morning and evening routines, but I encountered significant issues during the day. Because the serum is very thick and sticky, I am unable to apply any additional products over it, such as sunscreen or moisturizer. I tried using different tools and various product combinations to see if it would make a difference, but nothing could be layered on top of this serum without issues. Due to the texture, I have been forced to use it only at night.

Dried my skin out, strong fragrance
Bought for my dry skin and after 7 days of use, my skin is extremely dry with wrinkles and odd texture that wasn't there before. I honestly look 10 years older than before I started using this.

Great other than smell
Great product except I don’t like the smell, it smells like perfume.

Immediate impact serum
This serum leaves my skin glowing and plumped. I keep getting comments on how refreshed I look since I started using it as part of my morning and evening routine. The brand I used before that never felt like it made a difference, whereas this one’s effects were noticeable within 3-4 days of use. And I love the smell, which is fresh, clean, and not overpowering at all; don’t understand all the hate toward it.

NOT FOR SENSITIVE SKIN - PARFUM
So unfortunate that they included PARFUM or FRAGRANCE in the ingredients. I had to return this product as I have sensitive skin and am highly allergic. I assumed because it stated “tested on sensitive skin” and because it’s La Roche-Posay, that it wouldn’t have fragrance. Very disappointing.

Bad
Even "Allergy tested" and suitable for sensitive skin but it still has FRAGRANCE.

Excellent product!
Excellent product! I have psoriasis, and most products irritate my sensitive skin. My skin loves this serum, and it is the most effective moisturizer I've used.

Plumps up and hydrates your skin
Works amazing smells great and really plumps up and hydrates the skin. My GF has been sneaking it when I’m not looking and even she has noticed her skin being more plump and even wearing less makeup
