The first thing to do is to work out which type of acne you have - ordinary bacterial acne, staph acne, gram negative bacterial acne, candida fungal acne, malasezzia fungal acne, demodex mite acne...

Benzoyl peroxide is only effective against ordinary bacterial acne, and to some extent against staph bacterial acne..

Benzoyl peroxide will not control the other types of acne.
