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...

Too sticky

I love a good serum, and was super excited to get this one. Upon applying, I did find that it had a sticky texture once on my skin. It felt like I had something on my face, which I don't really like. I do however like it, since I did notice my skin softer.
I can see the difference!!

I want to start off saying that I gradually introduced this glycolic acid serum into my routine and did it only on days I knew I wasn't going to be in the sun for too long just to be on the safe side! As I've been using it more consistently, I've seen SUCH a difference in my skin texture. It's visibly smoother and the glow is on another level. I love that Kiehl's kept it simple with 7 ingredients in this! Really glad this ended up being a great match for my skin. I would 100% recommend, just don't forget to wear sunscreen!
Great product!

I really enjoyed this Kiehls glycolic acid. The smell is a little strong at first, but tolerable. I have started to see some slight changes in my skin while using this product. I feel like my skin looks more even.
Light and effective!

I am so glad I got to try this product. It is lightweight, not sticky at all, and works overnight. I like the consistency. It feels like a serum. Sometimes I put a thin layer of moisturizer on top but I don't feel like I have to every time because it isn't drying. I have sensitive skin and this product did not cause any issues. Highly recommend. A little goes a long way too, so the bottle will last you months!

Kiehl's Ultra-pure high-potency glycolic acid serum is a great exfoliator for both gentle and substantial results. I like how glycolic acid gives my skin a glow without irritation. I use this weekly but it could definitely be used more often in your routine.
