Anyone here have any problems with acne? Not the whiteheads or blackheads, but the cystic kind. The red bumps that are deep under the skin. I've been on an antibiotic and it's not doing anything. Does anyone know how long it takes for it to work?? I'm also using Retin-A at night, clindamycin in the morning, and a new less irritating benzoyl peroxide cream just on certain spots. I was just curious what some of you guys use and have some results with. I'm getting so sick of it.
