1. To prevent acne or folliculitis, isn't it most effective to apply and subject Benzoyl Peroxide (C14H10O4 I don't think this forum allows subscripts?) to skin as long as possible? I'm assuming that Benzoyl Peroxide needs time  to penetrate the skin and follicles. 

2. Aren't Benzoyl Peroxide creams or gels undoubtedly, unreservedly better than body washes? 

3. Body washes are usually washed off  within 3 minutes max. How can 3 mins. of skin contact with C14H10O4 suffice for efficaciously killing bacteria?
