Ultra Pure High-Potency Serum 1.5% Hyaluronic Acid

My new favorite Hyaluronic acid serum!!

I was skeptical at first due to the sticky texture after applying… but I LOVE this Ultra Pure Hyaluronic Acid Serum. The simple ingredients list does wonders for my acne prone dry skin. I HIGHLY recommend this!

Must-have for winter / dry skin

I absolutely love this product. I have very sensitive / dry / acne prone skin, and in the winter months I have a really hard time retaining moisture. This has been a game changer for me over the past year. I use it at least once a day underneath my cream / moisturizer, and it's definitely made a huge difference in areas where I would typically see flaky / dry skin. I'm particular about what I put on my face, and I love this serum because I know that Kiehl's uses clean ingredients that I don't have to worry about irritating my sensitive skin.

Beware if you have sensitive skin…

I used this serum for about three weeks and it made me break out so bad. I stopped using it and the breakouts stopped. I do have sensitive, dry skin. Given the price & results it’s a hard pass for me.

Must have for hydrated skin

Love love love this serum!!!! I used to use the ordinary hyralonic acid serum but did nothing and would get foamy and gross on my face. Thus serum is a god send for dry skin, I use acne medication that makes my skin very dry. This one completely hydrates my skin and it feels so plump and hydrated. People who say negative reviews about his done know how to use it. Use it on damp skin!!! I absolutely will repurchase this 100%!!

Its so good

This is a good serum best serum ever but i hope they make it cheaper at least 100 but its so  moisturizing 

I like this - I was using the ordinary and didn’t like the consistency- this is much smoother and doesn’t pil. I do wish it was a bit cheaper ….

Decent serum, fairly hydrating, but no huge effects - would not repurchase

Caused me to break out

I love most other kiehl’s skincare products but after having perfect skin this serum made me consistently break out when I don’t typically get pimples and I don’t think I can use it anymore.

New add to daily routine

I have acne prone skin and I’ve incorporated this into my daily skincare routine for about a month now and haven’t had any issues! Easy and hydrating under a moisturizer.

Caused breakouts

It hydrated just fine, didn't have the white flaking others have described. It did however make me break out, and I haven't had acne in YEARS. :( Returning.

A serum that works

I liked this serum, it provided moisture which made my skin look healthy. It makes your makeup look great. I tried many expensive serums and this one wins. It is reasonably priced and works.

If you want glowing skin- you need this!

This has kept my skin GLOWING! I can’t reccomend it enough! It’s not to harsh either!
