Benzaclin

I have mild to moderate acne, usually more mild than moderate. My main problem has been blackheads lately. It's been a year or two since I've really broken out since I've been using over the counter bp 10% everyday. My derm suggested that I use Benzaclin, and I figured it would be no problem since I've been using a stronger Bp all of this time. Ever since I've started using it ( only 3 days ago), I've been breaking out very badly which is really unusal for me. Is this just and initial breakout, will it soon start to go down? I didnt think Bp products had initial breakouts? I'm thinking about stopping because I didn't have this kind of problem prior to Benzaclin, I'd rather have the blackheads!

Sulfur soap

I just bought a bar of soap from the health food store called "MSM Soap", I think the brand is Born Again.. Just wondering if anyone has heard of this one before? It says it contains: Aloe Vera, Pure MSM, Camomile Extract, Calendula Extract, Vitamins A, C, & E and Essential Oil of Orange in a nautral vegetable base soap.
The only thing I am concerned about is the "oil of orange".. any opinions are appreciated!
