body{margin-left:12%}Product ReviewsRated 4.65 out of 5 stars405 ReviewsMost Helpful Positive ReviewThe best in the world!!!Okay, this might seem like typing too much, but no…. I'm not… I've tried various HA serums, but none worked this amazing, this soon…!!! I'm a crazy fan of Kiehls Products and I completely trust in their innovations. The ingredients, the texture, the quantity , the packaging all are awesome. It just applied so well from the first day, pretty much worked well with all other products of my skincare routine, And absolutely made my skin super healthy, bouncy, plump and hydrated within a nights time. Been using it for two weeks now and this most definitely is my favorite HA product now and shall be so for a long long time. I surely will repurchase… It hasn't released in the market yet, so I'm not sure about the price range, but I know kiehls products are slightly pricey, and this sun definitely justifies every penny…Most Helpful Critical ReviewNot for my sensitive skinI have used other hyaluronic acids and was out of my usual, thought I would try yours. It made my face feel dry and itchy plus being bright red. I stopped using it for a week thinking it might be something else. I used it again last night and I woke up to my face burning and feeling chapped. I couldn't recommend to anyone with sensitive skin.Reviewed by 405 customersKiehls is my fav!5brookesbe75 from undisclosedKiehl's Ultra Pure High Potency 1.5% Hyaluronic Acid Serum is a game-changer in the world of skincare.
