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.

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.

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

Drying, heavily fragranced product
I am so disappointed with this product! It has a strong, offensive, synthetic fragrance that is overwhelming, given it is applied to one's face. Also, it is very drying and irritating. I am now recovering from using it for a couple of days, realizing what was happening to my skin was due to this serum. I would like to send it back, please.

Strong scent
[This review was collected as part of a promotion.] What are you doing. I love your face washes and cicaplast baume, but the fragrance on this is unbearable and purely unnecessary

Disappointed
It doesn't hydrate like other HA I’ve used, it burns a little and it gave me a rash.

Actually made a difference in my fine lines!
This is one of the first products I’ve tried where I’ve actually noticed a difference in my forehead lines. Normally I’m actually very sensitive to smells, but this one doesn’t bother me. 10/10 reccomend.
