I have arm acne and have had them for a couple of years now. They used to be just bumps on my upper arms but now they are actually pimples. I use an acne wash in the shower everyday and I apply an acne toner I use for my face but it doesn't seem to work. I have a field trip in two weeks where we go to a water park and by then, I really want my arm acne gone. Do you have any tips or recommendations? Thanks in advance!
