I've been using this product for about a week now, and I have to say I'm pleasantly surprised at how smooth my skin feels! I have very oily skin, and I've noticed that in the last few days, my skin isn't as oily as it was before. Applying it didn't feel painful, but I did experience a slight prickly feeling that went away after around 12-24 hours. Overall, I would definitely recommend giving it a try.
