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.

Potent and effective

In a serum junkie and have tried all types from many brands, both mid- and high-end. I loved the consistency of the serum and it was absorbed by more pores quickly. I was also very relieved not to have an adverse reaction as I have highly sensitive skin that's prone to chemical burns. There was definitely a bit of a tingle so I wouldn't recommend sensitive skin girlies layer this with other acids, I would instead use this with a skin cycling routine.
Super strong
