it is good quality of facial product.

Very good product

itchy almost like pins and needles, some odd ingredient I don’t need

Hi, I have received the product, did not tried it. After checking the barcode discovered the cream is 1year and 11 months old. I think is not for face.

I use this product for my face, i love the texture of it, it is effective on my skin, I have used this product for 1 year and it changed my skin but i bought it directly from Kiehl's store. It is my first time to buy it online and i hope it is the same product.

Great product

This serum has been an excellent addition to my daily skincare routine. The texture is lightweight and absorbs quickly, making it easy to apply both morning and night without leaving any greasy or sticky residue. It layers well under moisturizer and sunscreen, which is important for everyday use. With consistent use, my skin feels smoother and more hydrated, and overall tone looks more even. The micro-dose approach makes it gentle enough for daily application without causing irritation, even on sensitive skin. A little goes a long way, so one bottle lasts longer than expected. This feels like a well-balanced product that focuses on long-term skin health rather than dramatic overnight changes. It’s subtle but effective, and over time the improvements become noticeable. A solid option for anyone looking to maintain healthy, youthful-looking skin. Smells great, value for money could be better

The BEST retinol I've ever used & I've tried 'em all. Saw improvment in my skin in a matter of days. No burning, irritation, deyness or redness. Absorbs beautifully. This will be a life long must have product in my skin care routine!

最近、しわやたるみが気になって何か良い化粧品がないか探していたところこちらの製品に行きつきました。 結論としては思い切って買って良かったです！すぐに結果が出て、肌にハリが出てシワも目立たなくなりました。

これはスゴイ！！！私には優秀でした。 A反応きましたが、その後はお肌ツルツルピカピカです!
