Product Overview

Use La Roche-Posay Hyalu B5 Pure Hyaluronic Acid Serum to plump aging skin and hydrate skin.

This powerful anti-aging serum is formulated with two types of hyaluronic acid and vitamin B5 for a complexion that is hydrated and healthy. Containing both high molecular weight and low molecular weight hyaluronic acid, this moisturizing anti-aging serum helps lock in moisture and leave skin feeling plump to the touch. Vitamin B5 helps repair skin's natural moisture barrier to help skin retain hydration for smoother, softer skin for longer. This hyaluronic acid serum features a fresh fragrance in an allergy tested formula and also contains Madecassoside and La Roche-Posay Thermal Spring Water to help soothe skin. Skin is left feeling supple and hydrated to the touch.

  • Can be used alone or can be used to boost the benefits of your daily moisturizer.
  • Features a light fragrance in an allergy tested formula.
  • Provides skin with both immediate and lasting hydration benefits.

Formulated with:

  • Hyaluronic Acid: Attracts water for an immediate plumping effect and long lasting hydration.
  • Vitamin B5: Also known as panthenol, this vitamin provides skin with an anti-inflammatory effect, helping skin to repair itself for a healthier-looking complexion.
  • La Roche-Posay Thermal Spring Water: Soothes and calms while infusing skin with vital nutrients and minerals.

Plump, smooth and moisturize skin with La Roche-Posay Hyalu B5 Pure Hyaluronic Acid Serum face treatment.

Great hydrating product

Love the feeling and scent of this. Use on a weekly basis to give my skin some much needed hydration and barrier repair.

Use to layer

I love my serums! This is super hydrating and a little thicker than some of my other serums. I will either use it alone, or the majority of the time layer over a thinner serum. Bonus is the fact that it has a dropper so you can control how much or how little you can use!

Dry Skin Relief

This is a good priced "staple" hyaluronic acid. I like to use this along with other products especially when you need a price relief, so I always keep on hand.

Great HA serum!

I was looking for a new HA serum, and this did not disappoint! Clean active ingredients (HA & B5) left my skin plumped and well-hydrated, mild fragrance did not bother me and aided in healing and restoring skin mantel.

String perfume smell

Strong, unpleasant perfume smell. Sticky texture. Unlike similar serums, this one produces no noticeable benefit. Wish I could return it

Love the Hydration, Do Not Care for the Pilling

I have been using this serum for a couple years now and love how easy it is to use. I use it every morning before the La Roche-Posay matte moisturizer. It isn't too thick and I don't feel it sitting on the skin after applying it. My only problem is that I cannot wear any foundation or other products on top without it pilling on my skin. Like little beads of product that are not penetrating the skin. A little frustrating but a small price to pay for the hydration this gives my skin. I wish it came in a little larger size as I go through one of these serums every three months with daily use.

Wonderful serum!

This Hyaluronic Acid serum applies very nicely. The serum is a little thicker, so it spreads well and a little bit goes a long way. Just let soak in the skin for a couple of minutes and then apply moisturizer and sunscreen. In general, La Roche-Posay products are high quality and every bit as effective as pricier brands.

Like it

This is my first time to use a hyaluronic acid serum. It won’t be my last. I apply it night and day before putting on other moisturizers. My face feels softer and smoother. This brand was my choice because I felt like the price was reasonable. Ordering this brand again.

La Roche Posay Hyalu B5 Pure Hyaluronic Acid Serum

My second time ordering this product. I really like it. I use it daily after cleansing ,Vita C serum ,and before Sunscreen. I have used B5 serum in the past from another company which was more costly. So this does the trick for me at a more affordable price point.

Good value serum

My husband & I have been using this product for over a year now. Great value, good result. We use it morning &,evening before La Roche Posay moisturizer. Result is comparable to the more expensive/high end serums. Happy customers here.

Working Wonders!

My hands needed a boost because of everyday chores. They needed a lift. Hand cream alone wasn't working for me so I decided to add a serum. I tried a very expensive one at first, which worked fairly well, but I needed something less expensive to use on my hands daily. I am so happy to say that this serum is working wonders for my hands. I am so glad I switched and the price is much more affordable. I will continue to purchase it.
