Apple Cider Vinegar worked and it was actually the easiest. I suffered with Tinea Veriscolor for 30 years, I tried almost everything to cure it but nothing worked other than calming it down. Simply get a good spray bottle and fill it up with ACV undiluted. Then simply have someone spray the entire affected area and rub it in a little for maximum coverage. Mine was on my underarms and back so I had my wife spray my entire torso down. Then I sat down on a towel, air dried and then went to bed. I didn't shower until the next morning.
Mine was gone after 3-4 applications.
