You have to use benzoil peroxide every day for it to be effective against acne. I use it at night and cover most my face with it and put extra on trouble spots. I find that b/p and an anti-bacterial soap such as Dial are the only things that work. I use the yellow bar of Dial soap. My face is used to it and responds well. I also find that not consuming Sugar
and alcoholic beverages help. Chocolate, in my opinion IS VERY BAD for acne. When my Acne
gets bad, I sit out in the sun. It works wonders. When dermatologists say sun is bad, it shows they don't understand the pyschological aspects of acne.
