What's the best back acne treatment?

Depending on the length of hair, the first question I ask is "Are you using any leave-in conditioners or products on your hair?" These are notorious for breaking out the skin. RINSE, RINSE, RINSE!

Secondly, where is the acne? Under the bra straps or band? This could be mechanical acne, caused by friction.

Eliminating those factors, the best treatment is to have regular back treatments with a clinician who can do effective extractions, then treat with a mandelic or jessner's peel. Mandelic has antibiotic properties to help kill the p-acne if the acne is in a pustule form. Jessners will help unplug the follicles if the acne is in the form of blackheads.

A good topical home treatment would be an astringent with salicylic acid.

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.
