New formula with perfume?
Been using this product for a year now. It definitely hydrates my skin and doesn’t cause acne (I don’t think). But the latest bottle I bought smelt so strongly of fragrance it’s like they added perfume in it. Not sure if it’s a one-off or if they changed their formula, but I can’t stand the smell of it now.

Hello Theresa. Thank you for sharing your experience with La Roche Posay Hyaluronic Acid Serum, Hyalu B5 Face Serum - Travel Size - 1.01 fl oz.

We hope you will give it a try soon!

Hello Chue! It is truly regrettable to hear about your disappointment following the transition from our previous serum, as we understand how significant it is to find a formulation that perfectly meets your skin's unique needs. While the discontinued serum focused primarily on long-lasting cellular hydration, the newer formula was developed to provide a dual-action approach by combining two types of pure hyaluronic acid with vitamin B5 and madecassoside to help both plump the skin and support its natural repair process. For those who previously relied on a more traditional hydrating serum, we recommend applying this newer treatment to slightly damp skin immediately after cleansing to help lock in maximum moisture and enhance the absorbing properties of the hyaluronic acid. This simple technique can often help the skin better receive the repairing and hydrating benefits of the more concentrated formula. We value your honest feedback as it is essential to our ongoing commitment to dermatological excellence.

Fragrance is very strong
Just got this serum and have tried it a few times. The texture is nice, but the fragrance is overpowering. I think I’ll find a fragrance-free HA serum instead. I don’t like the way it smells and I’m concerned it will lead to irritation. I use a bunch of LRP products that I like, so I’m not sure why they decided this one should smell so strongly of baby powder.

Hello there! Thank you for sharing your feedback and for your loyalty to our other La Roche-Posay products. We are sorry to hear that the fragrance of the Hyalu B5 Serum has been overwhelming for you, as we strive to create a sensory experience that complements the hydrating benefits of our pure hyaluronic acid and vitamin B5 formula. While this specific serum includes a fresh scent to enhance the application, we understand that fragrance preferences are very personal, especially for those with sensitive skin. To help the scent dissipate more quickly, we suggest warming the serum between your palms for a few seconds before gently pressing it into damp skin, which also helps the hyaluronic acid lock in maximum moisture. If you prefer a completely unscented routine, we recommend exploring our Toleriane Ultra Dermallergo Serum, which offers intense hydration and soothing benefits in a strictly fragrance-free formula. We truly appreciate your honest review and your trust in our skincare.

La buena hidratación que nuestra piel necesita.
Hyaluronic acid restores hydration to my skin and gives it that glow I need every day without leaving a sticky feeling, leaving it like baby skin. I love every drop I apply.

Needed hydration but will forgo the acne
I have been using this product for over 5 weeks. I have dry skin and wanted something to couple the moisturizer. On initial use I noticed some acne popping up and assumed my skin needed to get used to it. 6 weeks later and I am consistently breaking out with still dry spots on face with minimal improvement.

Good
It feels sticky when first applied to the face, but it absorbs quickly. As a base for retinoic acid, it works very well.

Hydrating but not good under makeup
This is a thicker hylaronic acid serum that really hydrates and plumps the skin. I loved how hydrated my skin was after using it but it definitely doesn’t dry down and works better overnight than under makeup.

My skin feels soft, like after I've done a charcoal mask, every single day. I have also had people ask me what I am doing differently, so I know the results are visible.

Hello frankw! We are sorry to hear that the scent of our Hyalu B5 Pure Hyaluronic Acid Serum has made it difficult for you to enjoy its hydrating benefits. While this formula is specifically developed with high-quality hyaluronic acid and vitamin B5 to provide intensive moisture and a smooth, plump appearance to the skin, we understand that fragrance can sometimes be a personal preference. A helpful tip for those who are sensitive to scents is to try our Toleriane Ultra Dermallergo Serum, which is specifically formulated as a fragrance-free, minimalist treatment to provide soothing and hydrating care for reactive skin. Maintaining a well-hydrated skin barrier is always our primary goal. We appreciate this feedback as we continue to prioritize skin health and comfort.
