You don't need plastic surgery. Not by a long shot.
The girls in magazines and on bill boards get digital plastic surgery. Photoshop can do things no doctor could even dream of. In addition, celebrities always get their picture taken from their best angle. Nobody actually looks as perfect as Hollywood makes them look.
Personally I think it's a waste of money. Lots of people end up looking worse because the work is obviously fake, and many of them remain unsatisfied because the problem is their self-image not their real image.
They average between $3,000 and $7,000 but all depends on where you live.
I know how you feel, especially with all these ridiculous shows on TV like bridalplasty, and plastic makes perfect, they make it seem like it's nothing. I could use a lot of work and I've actually done some research on procedures I want. Doubt I'd ever get any of them but I have thought about it.
I don't really like it but given the chance I would have some work done.
