I can see where people might need this if they have been in an accident, a life threatening fight, etc. I don't know if I would take this risk if needed, because I would be afraid they would mess up and make me look worse. I do care about other people taking this risk as well. If they were to mess up the procedure, they could sue them. I honestly don't think this is a good idea, because they may be professionals, but professionals make misakes, too. Nobody's perfect and nobody HAS to look perfect, it's the inside that matters, not the outside. But if people are willing to take that risk, they have the right. I just don't think I'd do it. That's just my opinion, though.
