My son did a few runs of Eurethamycin and it did the trick for him. He is big into sports and sweats a lot. Dr. Also recommended he wash his face often with acleansing soap. Meaning no oils in the soap. We got plain old ivory. Hope this helps.
Tetracycline helps a lot it's better than over the counter kills the bacteria and you can get it at a fish store for feed store they sell it for fish tank so you don't have to have a prescription for its the same thing as the lower grade
