This one says do you have an opinion about using NAC for skin picking disorder or excoriation?
There is somebody out there that knows that N-acetylcysteine is useful for something called “Trichotillomania,” which is a compulsive disorder of picking its skin and hair. Do I believe that it works? Yeah, it does. The problem, though, is that it takes a very high dosage of NAC for this purpose? It is usually around 1,000 milligrams 2, 3, or 4 times a day. Does it work? Yes. How does it work? Nobody really knows the exact mechanism of action, but N-acetylcysteine does work for that condition. Whoever asked that question is brilliant.
