What Are The Outcomes Of Plastic Surgery?

I am doing a research paper for my high school graduation requirement. My paper is on teenager plastic surgery. I have a few questions that will help me in writing my paper. 1.) What are the outcomes from plastic surgery? 2.) Are teenagers' expectations of plastic surgery realistic? 3.) Does teenage phases play a role in getting plastic surgery? 4.) A teenager with low self-esteem that is seeking plastic surgery and ends up getting a procedure, do they end up unsatisfied?
