Ultra Pure High-Potency 1.5% Hyaluronic Acid Hydrating + Plumping Serum

Price has gone up significantly with no improvement in size or formula. I plan on finding an alternative.

I use this on my “makeup days” and I do notice a difference in the plump and bounce of my skin. That being said I ALWAYS spray some sort of water mist and use a hydrating moisturizer on top of this because hyaluronic acid pulls moisture to itself so if you don’t add moisture on top, it will pull it from your skin. Just something to note in case you weren’t aware. But I do really like this product. I even bought it back up.

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.

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.

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.

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.

Leaves the skin supper glowy and bouncy!! Also doesnt leave the skin sticky, perfect for any time of the day !!

Hydrates my skin, feels bouncy and plump afterwards. Gives a great glow and keeps dry patches at bay.

Unfortunately for my wallet, I love this serum <3 It absorbs quickly and leaves a silky finish, no tackiness. Within a few days my skin looked noticeably more hydrated, bright, and my texture and lines were less stark. I apply after cleansing while my face is still damp. I have sensitive and acne prone combo skin, most products I try either leave me with an allergic reaction or closed comedones. I spent hours looking at every drugstore to luxury HA serum, looking for minimal ingredients for my picky skin and ingredients that were least likely to clog pores. This one was most aligned with those requirements The only reason I would give less than 5 stars is the price. Make sure to buy during a sale!!

Can’t use it around the eye. Product description on their website (duplicated here) is just wrong. The box states it cannot have contact with skin around the eyes. Also, Kiehl’s customer service is terrible.
