What are face lifts for and how would you know you needed one?

i was once a handsome looking young lad, now , because of life stress ive aged prematurely in my face , dark lines under my eyes, wrinkles , frown lines in forehead , open pores in skin…..

bleached skin around my forehead and temples where i excessively used to dye my hair years ago, i accidentally bleached areas of my skin…..i have a natural olive complexion.

minor physical deformities through injuries years ago and recklessness ; a crooked little finger that droops over slightly………..2 missing teeth at the front, bottom row ….im balding , taking a balding treatment medication.

and whats even worse is ive always been a perfectionist vanity person…..and my obsessive worries are making me focus on these things.

im now 32 and are far different from the perfect young lad i was because of ageing, life stress….its horrible to look at old photos and compare the difference.

someone recently in one of my recent questions suggested the '' surgery route '' to correct my premature ageing and minor physical deformities .

do you think there could be a lot of plus points by looking into surgery , even though im on fixed income and not able to afford it right now or in the near future ?

i cant decide what to do at this point : – to invest and use good skin care products like face washes and creams etc.

to save up for laser surgery or dermabrasion – ( a couple of yahoo users said this procedure has good results.)

OR
to consider something else ….. what is a face lift ? , could this surgery help me ? – what is it for ?

would i need it ?

right now its depressing because i couldn't afford the surgery route if i wanted to because i live off disability and would have to save up a fortune.

anyone offer an opinion on any of this ?
