Terrible fragrance addition!
Been using and loving this serum for years. Just opened a new bottle and was smacked in the face with a dreadful, horrible, cologne smell. It is truly awful…Why…WHY did you ruin it?! *Cries*

Good day to day firming use
I like the product, it doesn't make the skin feel tight but appearance wise works well on the daily basis. I love the smell.

Remove fragrance!!
I thought I ordered the wrong product when I opened my newest bottle. I had to come back and check it was the same item. The fragrance is way too much, please remove. I am all fragrance free and now I can’t use this item.

Can we get a fragrance free option?
I don't have sensitive skin and the fragrance was too much for me. Everything in my routine is gentle and nourishing since I have dry acne prone skin. Wanted to give it a fair chance, so I tried this out for months, always applied on clean and damp skin before moisturizing, and it still burned a little due to the fragrance. Hyaluronic acid is such a great ingredient but this product is overpriced for what it is and too much fragrance.

Hello! Thank you for sharing your experience. At La Roche-Posay, we aim to provide dermatological solutions for every preference. We’re sorry the Hyalu B5 Serum scent didn’t work for you, but did you know we offer several fragrance-free options? For deep hydration without any added scent, we recommend exploring our Toleriane or Cicaplast ranges. We would love to help you find a serum that feels and smells exactly how you want it to!

It works!
I was using the Dr Strum H Serum for a while and wanted to give this serum a try as a more cost effective alternative and I am happy to have made the switch. This serum is very effective and easily layers under my tertinoin and moistruizer. I also don't get all the complaints about the scent as it is very, very subtle, and goes away upon application. The texture of the serum is a little denser than the Sturm, so takes a little more work to ensure its spreads evenly, but a little still goes a long way here...i only need 2 drops for my face and 2 for my neck.

Why did you add perfume :(
Please take the fragrance out. I’ve been using this awhile and now there’s perfume in it. It’s a lot. Not pleasurable at all. I do love the new drip stopper at the top of the bottle but the fragrance has GOT TO GO for many reasons (not good for our endocrine system, it’s too strong for the face, etc)

Strong Fragrance Now
Came here to confirm what the long time users have been thinking. Yes, there is a ridiculously strong fragrance added now. It smells like cologne on my face. This was my favorite serum and they ruined it. 😮💨

Changed formula terrible!
They changed the formula! I’ve been using this for years and this new formula burned my face. I’m done with this! I thought I had received the wrong product then I noticed the packaging was different as well.

Morning-night routine
The texture is slightly thick but absorbs nicely into the skin without feeling greasy. Right after applying it, my skin feels plumper, smoother, and more hydrated-which makes it perfect for both morning and night routines. It layers really well under moisturizer and makeup too.

Irritates sensitive skin, has fragrance
Very disappointed that this is product has fragrance. This is not good for sensitive skin. Needs to be advertised as a product with fragrance, as all of the other la roche-posay products I use are fragrance free.

Hello EMG1916. Thank you for sharing your experience with Hyalu B5 Pure Hyaluronic Acid Serum. Wunderstand your frustration. When you have sensitive skin and have come to rely on a brand like La Roche-Posay for its "Dermatological Laboratory" standards, discovering an unexpected fragrance can be a real letdown—especially since many of their iconic lines (like Toleriane) are specifically formulated to be fragrance-free. We would like to assist you further. Please give us a call at: 888-577-5226 M-F 9:00am-5:00pm EST and give the reference number: 46190524 to the representative handling your call. It would be helpful if you have the product available when you call us. We look forward to assisting you soon.

Sensitive skin is a no for fragrance
If you have sensitive skin then this is not for you. The fragrance in this will give you a tingling itchy feeling. I feel like if this product did not have fragrance then it would be amazing.
