Kiehl's - Retinol Skin-Renewing Daily Micro-Dose Serum, Reduces Wrinkles

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

This is the latest product in my now all-Kiehl's facial care routine, replacing and bettering previous high-priced salon brands. I use this product at night a few times a week -- along with Kiehl's eye cream and calendula toner -- and see visible improvement in my skin texture and tightness. During the daytime and all other nights I used Kiehl's moisturizer instead of the retinol. This product is more effective yet gentler than any other brands I have used --- at a great price for the value it provides. Highly recommend this product.

I nearly never write reviews, but this product absolutely requires one, especially with how pricey it is. I am in love with this serum! I've always thought I have pretty good skin. I'm 42 and no major blemishes or anything, I've always thought that as long as you follow a steady skin care routine it isn't important to buy the expensive stuff. However this has officially become my one indulgence. I noticed a difference within 3 days of using it nightly. I noticed it without even trying or really looking for results since I had just started using it and wasn't really expecting to see any so soon. I noticed it after the 2nd night using it, the following morning when applying my tinted moisturizer I was taken aback by how smoothly my tinted moisturizer went on, my skin was so smooth that it just glided on so smoothly, my pores were so tight, I was in awe. I applied it again that night and the next morning I was pleased to see that it was that same smooth texture to my face. I can only imagine how my face will look when I 1) start using my night time moisturizer over it and 2) a few weeks of using it has passed. As a side note, I don't have overly sensitive skin but my skin has always been very soft and easily abrased, and I've had no bad reactions to this serum as of yet.

Excelente.

Great retinol for sensitive skin!

It doesnt smell bad like other retinol ive tried. But also not sure if it “works”. Im still hopeful and use at night but its only been a few weeks

I’ve been enjoying this Kiehl’s retinol serum as part of my skincare routine. The lightweight texture absorbs easily and doesn’t feel heavy or greasy.

It makes my face glow.

Great product

使い始めて 化粧のりが良くなって良かった。

Ich liebe dieses Serum mit Retinol. Ich habe es schon mehrfach nachgekauft und benutze es regelmäßig. Die große Verpackung hält bei mir sehr lange und hilft dabei Hautalterung vorzubeugen.

No tengo resultados ya que lo estoy usando hace muy poco. La textura es ligera y absorve rápido. Se recomienda usarlo por la noche en cara, cuello y manos. No puedes tomar el sol si la llevas puesta.

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!
