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...

This serum is now a statement in my skincare routine. Even after the first day of using it, my skin is smoother, marks are reduced, and overall looks renewed. The bottle is a good size and will last a while as a little goes a long way with the product. I highly recommended this to anyone who wants a glowy, fresh, and renewed look.

This glycolic serum is great! I love that it doesn't feel abrasive on my skin but it is so effective on my stubborn acne! It's clear with no smell and a nice formula!
Not what I was expecting

I truly love this brand and they do deliver quality products, but this particular glycolic serum seemed to break me out. I have uneven skin and breakouts and after applying this I woke up to my blemish looking irritated and red. I realize the potency of a this serum and I do like that it has very few ingredients but I just don't think this is for me. I will say I the last couple times I used it, I mixed it with moisturizer and it seemed to not irritate my skin as much as that first time.

Good, but give it time...

This serum was a thicker gel-like consistency. Upon trying on my face, it was sticky and also burned a bit after applying (I applied it to freshly washed skin). I didn't really see a big difference in my skin tone and evening things out, but the texture of my skin did feel much tighter during the week I tried it. For reference, I am oily, acne-prone and have some hyperpigmentation. I also did not experience any acne from this product which was great. I will continue trying this to see if it gets better with time.
