Not for sensitive skin ...

Upon receiving this complimentary product, I was super excited to finally get a chance to try a Kiehl's brand product. The Kiehl's Ultra-Pure High Potency Serum 9.8% Glycolic Acid arrived in a semi-sturdy red and white branded package with black lettering. The serum is enclosed in a small glass bott...

Good ingredients but didn't work well for me personally

This is the second Kiehl's product I've tried and wanted to love but just didn't have success with. The ingredients are simple, the packaging is understated and clean, and the serum is clear and watery, so in theory I should have been able to layer it under my moisturizer. For me, the product was ve...

I wish this would work, but I had to stop it after using it every day for a week because I noticed I developed small pimples on my forehead which used to be really clear.... could have been purging but I didn't want to risk it..

Bottom Line Yes, I would recommend to a friend

Really good product with simple and effective ingredients. Love how there is nothing extra added into it. Sinks in and absorbs well to the skin and does what it's supposed to do. Would recommend!

I absolutely love this! It's made with SEVEN ingredients and even though I have an extensive amount of skincare products this is the only one of its kind. I love the serum, it absorbs quickly, doesn't stay tacky, and you can see the results within a week or two.

Bottom Line Yes, I would recommend to a friend

I love this stuff. I noticed a major difference in my skins texture in just a few days. I have used other glycolic acids in the past but this one for sure beat them. Since it was a higher concentration I did do a patch test before and I was able to use it without any complications. I loves how nicely it was absorbed as well.

Bottom Line Yes, I would recommend to a friend

The Kiehl's Ultra-Pure High-Potency Serum 9.8% Glycolic Acid has made my skin so much healthier and appealing. I love to incorporate it into my daily routine now to keep the glow I have been noticing. I would highly recommend this and definitely will buy a bigger bottle for myself and my wife.
