Acne - prevention and remedies?

n May 18, 2010 I got Botox in my forehead. Within a day or two I had 10 or 12 small bumps between my eyebrows. I have NEVER had a history of acne, I have never taken medication for acne treatment. I don't understand it. It has been almost 5 months, and still, the bumps remain. I try to pop them, exfoliate, I bought a $300 skincare line that I use diligently twice a day, I've put rubbing alcohol on them... nothing even phases these bumps! It's terrible!! I am going to the dermatologist next week to try and find a solution for my suddenly developed acne, that will not go away! It's almost time for more Botox, my wrinkles are returning... I don't know what to do. Seems like I'm going to be stuck with bumps and wrinkles!!
