Long acting hyaluronic!

I know many complain about the fragrance edition, but as long as my skin is not compromised from a chemical peel or retinal product, this has always been my absolute favorite hyaluronic. It locks moisture and immediately and keeps it in. And as for the fragrance, it smells really nice. It can be a little heavy but I have also found that mixing it with other lighter hyaluronics works perfectly as well.... And brings down the fragrance level a little.

My new favorite serum

This B5 serum has viscosity; it's not at all watery. It makes my face glow.

Heavily fragrances

I don't see how anyone can apply this on their skin. Let alone face. It has fragrance in it. It felt nice but heavily fragranced like a perfume.

Liquid gold hydrator

I bought this product to use on my face, neck and chest area to help with aging and wrinkles. It has been so good with plumping up my skin. My dermatogist said at my annual appointment the other day what are you doing with your skin it looks amazing and asked for the product name so she can buy it. Strongly recommend this product to help hydrate your skin.

Best hyaluronic

Love this stuff. Along with a few other products, this has made a huge difference in reducing fine lines and making my skin look plump and moist. I use it in my day and night time routines.

Dermatologist recommended

My dermatologist recommended this for me as part of my skin care routine. The price is worth it. It’s hydrating, but absorbs well into your face. I can’t tell it’s applied once absorbed. It sits well underneath my makeup and has helped the overall look and feel of my face. I’ve had acne prone skin, but now I described myself as combination skin.

B5 hyalluronic acid at a good price

I have used this B5 hyaluronic acid from La Roche Posay for a a couple years and it keeps my skin looking hydrated and plumped. at a good price. In the winter i even use it on super dry skin on arms and legs and feel it helps decrease the look of crepey skin.

Great for sensitive skin

I had been trying to find a serum with hyulauronic acid that worked for my very senstive skin....so far so good! I have found this to be the one. I was worried about the fragrance as mentioned by other reviewers, but it dissipates quickly so no problem there. I like the thicker consistency too, for my very dry skin. Waiting to see how it works long term, but I'm very happy with results so far!

Moisture in a Bottle

Started using this after a friend's recommendation. I layer it over a Vitamin C first thing in the morning. Great hydration for my dry, sensitive skin in our dry climate. Will continue to use, especially over the summer and fall months.

Great Hyaluronic Acid

I like this product line a lot. This is very good stuff, and it immediately absorbs into your skin. It’s not slick or shiny. I started using several products in their product line!

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
