Hey man, I agree that currently no one has a clear answer regarding the acne problem, but I'd like to give my two cents, as this approach might be helpful for someone.
Skin diseases and also hair problems in general are occuring after a so called 'conflict of seperation'. This could mean that you either akutely wanted to be seperated from someone/something but couldn't/can't, or that you wanted to be united but couldn't/can't. Just to give an example, someone's partner breaks up with them, which might lead to circular hair loss on the head if they interpreted the situation as an unexpected ugly-seperation-conflict. When it comes to acne I would say you got unexpectadly seperated from an aspect of yourself but you aren't willing or aren't able to accept that, which is why acne tends to occur during puberty and adolescence as these are times of changes. We are obviously quite identified with our faces and we react sensible to it changing. You can try to think about when exactly the acne started, and then find the conflict right before that time.
