I think it's okay for anyone to have plastic surgery, it's their life, so they should be able to decide if they want any or not. I personally would not want plastic surgery, I'm fine with the way I look.
I'm getting one soon. Already consulted with many surgeons. And now I'm narrowing my choices down to who I think will give me the best results. If you're getting a nose job, please ONLY choose someone with a Otorhinolaryngology credentials. If they don't, then don't even consider them the slightest even if they are the best in town. Reason being is that, your nose is a very complex part of your body, and first and foremost you should he focusing on your health, and breathing before anything else.
Plastic or even cosmetic surgeons only alter your appearance to mask the underlying problems while an ENT surgeon with an extensive experience in rhino/septoplasty will actually fix your appearance as well as any underlying issues that is obstructing your breathing and such.
I'm also getting some Fraxel CO2 laser for my acne scarring. I've tried ProFractional at 200 microns with good results but It's time for me to do more aggressive forms of treatments.
I had plastic surgery to reduce a lump of fat on my stomach so I wouldn't really class that as cosmetic, I had the surgery as the lump kept growing but it was liposuction I had so would this be classed as cosmetic?
It's your body, so you do whatever you want... I personally would not do a plastic surgery, I don't think that I'm perfect but I'm okay with my flaws, but if it HELPS you to get better then yeah, do it (don't end up like MJ or Donatella tho.)
Confidence is a precious thing most don't have at birth. If you like the results and you're more confident because of it, I'm more than happy for you! PS isn't just for improving your looks, it's for improving your life (when done correctly)!
I have considered getting a nose, ptosis repaired, and a chin implant or a sliding geniplasty. Then if I have had more money, I'd get cheek bone fillers and laser treatments with mild injections to my cupid's bow and laser for hair face and body removal.
