Kiehl's - carolb review for Ultra Pure High-Potency 9.8% Glycolic Acid Serum

Loving this serum, it from Kiehl's, I was gifted this and would love to try the rest of their products. It's a high potency Serum with glycolic acid, so you only need a small amount. It felt ok on my skin, I didn't experience a sting with the acid .
