Well, if the Accutane can’t be afforded by prescription, it probably can’t be afforded black market either. (Sometimes things are the reverse on that but not usually.)
The dietary changes I suggested don’t necessary cost much if anything.
It’s also possible that you are oversoaping and stripping oils to such an extent as to make things worse, as mentioned also in my previous post.
Acne cannot be eliminated by trying to clean all oils out, no matter how severe/frequent that cleaning is. Doesn’t work. Clean is good, but stripping oils out excessively is not.
While I need to warn you that there is at least one study linking chronic Vitamin A supplementation (as Vitamin A itself, that is to say retinol, not as beta carotene) to shorter lifespan,
a brief time at 10,000 per day will not kill, and for what it’s worth the FDA sets that as their upper safe limit (but since when are they right about any nutrient recommendation? Usually they are too low but it would hardly be impossible for them to be unsafely high, in terms of long-term effect.
And 10,000 IU Vitamin A (not as beta carotene but as Vitamin A itself) may help. But it’s not addressing the fundamental problem, which is largely abnormal lipid metabolism in the skin. The dietary approach I suggested above directs itself at an underlying cause.
Lack of Vitamin A is not an underlying cause of your problem, but high Vitamin A may be a partial aid.
I would not worry about a few months at 10,000 IU. Personally I would not go longer.
For that matter, Accutane (a Vitamin A derivative) is toxic, too.
