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.

Over the last couple weeks of using this both on my face and 'drum rollll' my underarms, it had Abdul tell helped clear up some stubborn discoloration of the skin. I've noticed clearer skin and more even tone. It doesn't sting, but I do primarily apply this at night as the sun and this don't mix well.

It has a moderate, pleasant scent. I like the way it smells, but I don't think it is a scent that everybody would particularly care for. I would describe it as an earthy scent I suppose. Only need a couple drops at a time. Feels light and smooth to the skin. It can be a bit sticky when it is drying though.
Nice product

I really enjoyed using this serum. It is similar to other serums I have used. I do like the dropper bottle and formula. The product felt very hydrating and left my skin feeling very nice. A little bit goes a long way!
