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 Kiehl's Ultra Pure High-Potency Serum 9.8% Glycolic Acid is okay for my skin type (combination, hyperpigmentation, and sensitive skin). I have been applying this product twice a week followed by a moisturizer. The texture of the product feels smooth and soaks right into the skin making my face feel supple. I love that the product has only 7 ingredients. However, in the few weeks I've been using this product I have not seen any noticeable differences in my hyperpigmentation scars. Additionally, this product leaves a burning sensation if there are any micro cuts or fresh pimples.

I was nervous to try this because "high potency" and "9.8%" had me concerned that this product would burn. I personally didn't have any issues at all. This serum is light-weight with a watery texture and doesn't have a scent. I haven't used it long enough to determine if it is truly effective, but I really like this brand and would definitely give this product a try if you're looking for a glycolic acid.

Bottom Line Yes, I would recommend to a friend

I found this to be such a nice serum! I have very sensitive skin, so I was very worried going into this sample. However, that worry is no more. Though there was a stinging when I applied this, it didn't last for long. I was a slight bit red in the cheeks, but I expected that. It's not too sticky, very blendable, and doesn't smell much. My skin feels so good!

Bottom Line Yes, I would recommend to a friend
