My frind with Acne has not yet done any of those procedures.
It is a bit diffuclt because it is a young modern male and he is very brainwashed. So I just waited for posts like yours to finally attack him.
It is hard to discuss his skin condition with him (we are not such close friends) and talking about him having parasites is even harder, but I want to help and I am 100% sure it will work and he will say thanks to me in the end.
Thank you JoeMamma, I will do my best to realise my plan.
