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.

This serum leaves my skin glowing and refreshed. It exfoliates and hydrates the skin. Also, the serum helps with discoloration and uneven skin tone. I have sensitive skin and I am still able to use this product with no issue even though it contains a high potency of glycolic acid. Overall, I would recommend this product.

I recently picked this up and I really enjoy it. I don't know if it's really a beginner acid, but it's really nice and I notice a big difference in my skin after using it. One of the first things I noticed was that the pores on my nose where much smaller and didn't look as congested. It's also made of only a handful of ingredients so theirs much less of chance of an unsavory interaction with any other step in your skincare routine.

This is the first year that I really started incorporating actives into my skincare routine. My skin tolerates salicylic acid really well but this is the first time I've ever really tried glycolic acid. My skin loves it and all the texture on my forehead and around my nose has significantly decreased.
