There are a range of acne treatments that may be tried ...
Accutane is a treatment but not usually any of the first tried to sue to its potential side effects.
Epiduo is a good product -- has he tried that ?
Doxycycline is similar to minocycline but usually cheaper ....
Other antibiotics may be tried ...
Tazorac is helpful -- has he tried that ?
A regimen of washing face with a gentle scrub or extolling twice a day would usually be of help....
Clindagel is a good topical antibiotic for it ...
Follow up with his dermatologist I would recommend at 6 week intervals to help fine tune his treatment
Accutane is potential but there are so many other less risky trrwatments I think he is best to try a number of regimens FIRST
