I've had spots since my pre-teen years.

Not really bad acne but I've always at least one pimple to deal with. For me, it has always taken a week to two weeks to get rid of the spot completely. They would shrink after a day or two but then because I have sensitive skin, I would end up with a red or light brown spot on my face. This book has given me the right way to handle that. Are they showing improvement but just taking a long time to go away? My experience with my own skin and having known other people with the same problem is that you shouldn't have to deal with them for more than a few days to a week. I hope this helped. Good luck.
