Pure Serum 1.5% Hyaluronic Acid

Breakouts

When I use this I break out in tiny whiteheads along my cheekbones. Very weird. I've been using it on my legs so I don't waste it and honestly don't notice any difference in hydration.

Gentle quenching hydration!

If you have sensitive, dry skin, this hyaluronic serum formula is absolutely amazing. It has no fragrance and only 7 ingredients, so if you are prone to skin allergies, the likelihood of getting an adverse reaction is much lower. It soaks straight into the skin without leaving a sticky residue, and its very light, so its perfect for layering during the daytime. While it's more pricey than other options, I think its worth it if you have sensitive skin like me that reacts to a lot of products.

Must have

I was using the ordinary serum and thought I loved it until I tried this. No sticky tacky feeling and my skin is so plump and hydrated.

Hydrating, gentle, and no fragrance!

This Kiehls hyaluronic acid was very gentle and hydrating. The consistency is the perfect blend (not watery or super thick). I love that there was no fragrance. I have dry, acne prone skin, and I did not break out! A win, is a win! I am glad I purchased this product and would recommend to others.

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.

Super

Tolles Serum. Spendet der Haut sofort Feuchtigkeit, zieht schnell in die Haut ein, ohne einen klebrigen oder öligen Glanz auf der Hautoberfläche zu hinterlassen. Notwendig für jeden, der Roethinol verwendet. Ich trage es nach dem Serum mit Retinol auf, dann trage ich eine Feuchtigkeitscreme auf. Am Morgen sieht die Haut ausgeruht, frisch, gesund und jung aus.

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%!!

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.
