Acne on the back is difficult to treat because of the problem of physically reaching the affected area. It's impossible to reach all of the affected areas to apply a cream or lotion. That is why I always choose cleansers first in treating back acne.
I like cleansers with glycolic or salicylic acid. These help unclog the pores by exfoliating the top layers of skin, releasing the oil and debris that is trapped in the pores and also decreasing the likelihood that new clogged pores will form. When these treatments aren't enough, it may be best to try an oral antibiotic.
It is also important to remember to shower soon after exercise. If you are sitting around in sweaty clothes after your workout, the pores are more likely to get clogged and trigger a breakout.
