I'm not black, so your skin most likely responds differently to products than mine does, but I might have some helpful tips. First off, products like Proactive and others, don't work very well. You should start off by drinking more water and trying to stay away from sugary foods. If that doesn't help, ask your doctor or dermatologist for antibiotics. She or he will mostly likely give you a 2 week prescription for Tetracycline, but ask for Amoxilicilian. But both of these options take time to work, so in the mean time, Covergirl, Almay, Physicians Formula, and Neutrogena, offer gentle, fragrance-free make up, with salicylic acid and other acne-curing ingredients in darker colors.
