I have only used this for 4nights now (I use it only at night) and my goodness!!!!!! My face is BABY BOTTOM SOFT- NO JOKE!!!. It stings though, so you have to be careful. However, the stinging doesn't last. I have been following  DermTv Dr for a while who suggests incorporating an exfoliant into one's regimen. He particularly likes glycolic acid and i can see why. This product from glycolix is one of the best glycolic acid-base products I have used. Worth every penny!!!
