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 was a great serum to help smoothen the feeling of skin. I felt hydrated and like the consistency of it. It felt a little bit "slimey" on my skin but nothing really to write home about compared to many other serums on the market. Overall good product, just very expensive.

Bottom Line Yes, I would recommend to a friend

I really like this acid product. My skin is sensitive and I use tretinoin, to I have to be careful with the amount of acids I use. This stuff was so gentle on my skin. I love that I can put it on before bed at night. My skin felt fresh, clean, and smooth the next morning after I washed my face.

Bottom Line Yes, I would recommend to a friend

I received this product complimentary and I have sensitive skin but textured. In order to keep my skin looking fresh, I need to use AHAs and glycolic acid. I was pleasantly surprised by this product because it has diminished the pores and texture on my skin from continuous use of about a month. I can see the difference already. Best part is it does not irritate my skin or have a smell. I definitely recommend!

Bottom Line Yes, I would recommend to a friend
