LOVE this hyaluronic acid!

My favorite hyaluronic acid, So silky smooth, doesn't pill, and definitely plumps my skin. I'm on probably my 6th bottle. Remember always apply to damp skin. It's amazing!!

High Quality

I would recommend this serum. It visibly plumps skin! I tried a couple hyaluronic acid serums and this had the same results as another product three times the price.

Love this so far!

It is quite sticky, and I find that I have to apply a cream on top, but it seems nice. I hope to see the plumping soon! Nice medium perfume scent too.

Silky hydration

I have used many Hyaluronic acid serums. This one is really nice and best yet, affordable. I wash and tone my face and while damp I use Hyaluronic acid. Next I layer my serum and moisturizer. This Laroche-Posay has both the 2 types especially the sodium hyaluronate which is a smaller molecule so soaks in better. The addition of the B5 is also a bonus. When you are a woman of a certain age, you need all the skin plumping you can get. I'm never without and it's the perfect size for travel. I love it.

Great serum with 1 pitfall

It's very moisturizing and leaves my skin feeling soft and dewy, but unfortunately I am only giving it 3 stars. The problem is the scent - it's overwhelming, and it burns when I apply. I don't have super sensitive skin, but I the fragrance is strong in this one! Really a shame!

strong scent - sensitizing

I've heard so many good things about this serum, but the moment I opened the bottle I became worried because the scent was so strong. I tried applying it to my skin but had to wash it off almost immediately because the scent lingered and bothered my allergies. I'm sure if I'd left it on longer it would have sensitized my skin. If anyone knows of another good hyaluronic acid serum with panthenol hook me up!
