La Roche-Posay Hyalu B5 Hyaluronic Acid Serum – Review

Here’s a review of another fantastic product by La Roche-Posay.

The formula is pretty straightforward; two types of hyaluronic acid for optimal hydration, panthenol (vitamin B5) soothes and helps to repair the skin, and madecassoside, the active ingredient in Centella Asiatica, is anti-inflammatory and helps to stimulate collagen production. We can also find good old glycerine and dimethicone for more robust moisturising action. The serum contains alcohol, but it’s drying effect is mitigated by all the beautiful ingredients mentioned above. Alcohol helps ingredients to penetrate better and work faster in the skin. The product is suitable for all skin types, but there’s a bit of fragrance as European skincare formulators love to add fragrance to everything. 

This serum resembles the SkinCeuticals H.A. Intensifier; they both have a similar texture of watery gel that melts into the skin. This product is very agreeable, and it is easy to use, works well with other products, and does what it say on the box. It leaves my skin plump, soft, and with a feeling of deeply hydrated skin. I enjoy using this serum a lot. You can use on its own or on top of other products, just remember to seal it in with something as hyaluronic acid pulls moisture out of the skin. I don’t have much to say about this product, other than it’s fantastic. 

I highly recommend this product; it delivers promised results and doesn’t cause any issues. If you’re looking for a good hyaluronic acid serum, then this one is a great option to consider. This product has one advantage over the SkinCetuicals’ serum as it doesn’t contain essential oils, so if you can’t tolerate them, then this serum is a much better option for you.

  1. Hi again!

    Reading lots of your posts. I find them very helpful!

    I have tried this serum in the past and found it very sticky and shiny. When I used the serum previously, I would apply to cleansed skin. But it never really absorbed or dried. And my skin didn’t feel hydrated or plumped. Perhaps I was using it wrong? Did it remain tacky on your skin?

    I ask because I am considering trying it again, as I was given the Hyalu B5 Ampoules as a gift from a friend, and would like to use the Ampoules along with the serum.

    • Hi,

      That makes me very happy, and I am glad that I can help.

      I have never experienced that, but I know some people do because after posting this review, I received a few messages from people who had experienced the same thing as you did. So I’d say apply it right after cleansing, when your skin is still damp and use a small amount, about 2-5 drops, as it’s pretty dense. Also, do not forget to apply a moisturiser or something similar to seal in the hyaluronic acid, otherwise, it will draw the moisture out of your skin.

      Honestly, if this serum didn’t work for you, I wouldn’t say just try something else. There are so many options on the market; you could try the L’Oréal Paris Revitalift Filler 1.5% Pure Hyaluronic Acid Serum(I haven’t tried it), which is a bit more affordable version of this product. There’s also the L’Oreal Paris Revitalift Pro Retinol Hydrating Smoothing Serum (I haven’t tried it), despite the name, it contains only retinyl palmitate, which is an antioxidant and doesn’t work like retinol. Though the serum is quite interesting, it has Bifida Ferment Lysate, which provides probiotics and nourishes the skin; moreover, there are glycerine, hyaluronic acid, and soy proteins in the formula; all work help to increase the moisture levels in the skin. Technically, it’s another hydrating serum, but it is marketed as something else. Or you could try Hada Labo Tokyo’s serum or the Hada Labo Tokyo Plumping Gel. You could also get the original Hada Labo products.

  2. Thank you so much for your detailed reply! I appreciate you taking the time.

    That’s good to know it was not just me that had that experience with the Hyalu B5 Serum. I can’t remember if I was using a moisturiser on top. I only used it in the mornings, and I think I was just applying the Anthelios Invisible Fluid sunscreen, which was also very shiny.

    Thank you for all the alternative suggestions. Unfortunately, none of the Hada Labo products I have tried worked for me. They didn’t hydrate my skin for some reason, even with moisturiser on top. I will look into the L’Oréal Paris products you mentioned. The Pro Retinol one sounds very interesting, even with the misleading name.

    Thank you again.

    • You’re welcome!

      The new LRP fluid sunscreen is very shiny indeed.

      Perhaps you could consider using something more occlusive like SVR’s Sebiclear Hydra moisturiser, since the lightweight, HA-based products don’t work for you.
