burned my face off, not worth it, its very strong.

Don't buy unless you want severe breakouts!

Fool me once...Bought this in the store after quickly browsing through all the 5-star reviews. Realizing now most of them are 'incentivized' and have oddly similar language, sigh. Well, this product straight up ruined my skin barrier. I gave it a try a few times with several weeks in between and both times, woke up to red, SEVERELY broken out, irritated skin. Third ingredient is alcohol - tells you all you need to know. It has been a week since the horrible flare up I got from using a small bit of this product, and my skin is just now recovering with a ton of babying and slugging.

Saved my skin!!!

Helped get rid of my under the skin bumps and texture. Also super gentle!

Would recommend giving it a shot!

I've been using this product for a few weeks now, and I've noticed that my skin tone has been evening out some and it's helping brighten my complexion! I wouldn't say it's been anything spectacular, nor do I feel that it's helped with my skin texture, but it's shown some results! I would at least recommend others to try it because I'm sure this would work wonderfully for some people. I think I would try this with another moisturizer than the one I'm using now (which is another new product I'm trying), because I'm curious to see if with a more tried-and-true moisturizer, it would yield better results for me. But I'd definitely give this product a shot!

On my second bottle. Will be included in my routine from here on out. Make my forehead lines very smooth and help achieve a healthy glow/ shine in my skin.

Amazing!

This has helped reduce redness and evened my complexion and has worked quite quickly. I bought it after trying out a tester and it will now be a staple in my skincare!

I can’t go without it!

Whenever I don’t use this, I notice the difference! It’s the perfect blend of a strong exfoliator but not too much that it really burns and stings. Kiehl’s kills it like always!

Super efficace

J’ai acheté ce produit après avoir vu les bons effets de la crème de jour. Je ne suis pas déçue car il réduit visiblement l’apparence des pores et donne à la peau un aspect rebondi.

A must have skin product!

After using this product for a few weeks my skin had been so soft literally erasing so much texture. I do highly recommend using a moisturizer right after due to it being a little drying but outside of that this product is it!

Skeptical for sensitive skin…initially

I was pleasantly surprised by this product! It’s Kiehl’s so there is a certain standard, but once I moved this product away from my super sensitive face to other textured parts of my body (back, shoulders), I really enjoyed it. I don’t typically typically reach for acidic

A Worthwhile Investment

I’ve been using this product for about a month and man oh man. I’m in love. It does what it’s supposed to and more. It does take a bit of adjusting and figuring out which products work well in addition to this one, but once you figure it out it is well worth it. I have eczema, large pores and horrible under eye bags but within about 3 weeks I noticed a significant change in my skin. As long as I use the product every night, my eczema is long gone, my pores have shrunk and I notice my under eye bags are so much lighter. I’ve cut my routine down by two steps because this glycolic acid actually does the work that most products only claim. I cannot say enough about how much I love Kiehl’s Glycolic Acid. It is an investment but one worth your while. After a month of use, I still have 85% of the bottle to go so it will definitely go the distance for you whenever and wherever you may need it.

great product !!

I really like that this formula has glycolic acid because it’s been helping with evening my skin, i used to have some small spider veins on my face that I feel like are diminishing because of it. I also love how it feels on my skin because it leaves me feeling super moisturized and smooth. I feel like i started noticing some changes to my skin within the first week ! i love this product
