Is treatment necessary? [benzoyl peroxide] [acne treatment]

I have what I would call mild acne. I have a few pimples occasionally, but a few pimples at a time around my jaw line maybe twice a month.

Since Im not a big problem with acne, it is necessary to use an acne treatment (salicylic acid, benzoyl peroxide), or is keeping my skin pores and clean (like Neutrogena Deep Clean) enough? Deep Clean progress deep into the pores clean to remove dirt, oil and makeup . This is enough to prevent my pimples?
