Before this gets moved to the prescript section, this is not about Accutane, it just happens to be how the story starts.
I had severe acne (conglobata it seems) since I was around 10, my chest and back were completely covered. My face had tons of daily cysts as well but only on my cheeks and nose, for whatever reason my forehead and jaw were spotless.
I went on a very high dose of accutane (160mg daily/5 months), because my acne was that severe and I had to wear gauze all the time to not soak my shirts in blood etc. Lower doses were showing nothing so I was upped to that amount, at about 180lbs.
It worked like a charm, to this day my nose, upper body and cheeks just won't break out. But a few months after tane, the weirdest thing started happening. My forehead started breaking out like crazy, within weeks I was getting around 5-10 new bumps just on my forehead every few days. Next, my legs were suddenly covered, as well as my butt, I mean completely covered in zits.
Fast forward fifteen years and thee extra courses of accutane, antibiotics, probiotics, anti-fungals, topicals, athletes foot creams, shaving the hair, growing the hair, doing nothing, scrubbing like mad .... I've tried and tried and my forehead, scalp are as bad as ever.
It comes and goes, sometimes my scalp stays mostly clear for a while but legs break out a ton etc.
I don't believe this to be acne, there's no way two extra doses (high doses) of accutane wouldn't have even made a dent on the issue. It also makes no sense that this all started after that first high dose of accutane....
Doctors are puzzled and have long given up, but maybe someone out there has an answer. All I can think is that the insane amount of isotretinoin in my system did something to permanently damage my skin in some way to where it can't function normally etc. I literally traded my clear areas in exchange for my acne prone areas, makes no sense.
