How old do i need to be before i can have plastic surgery?

Depends: At 30 years old, you are past any kind of age restriction for cosmetic surgery. Seek a consult with a plastic surgeon to discuss your cosmetic goals further.

Depends...: Plastic surgical procedures are performed on patients ranging from early childhood to the geriatric age groups. Patients under the age of 18, unless emancipated minors, will need parenteral consent. Best wishes.

Depends on issue: Plastic surgeon operate on newborns, (congenital abnormalities), and old people, (reconstructive or aesthetic). It all depends on what is needed. Federal guidelines Prohibit cosmetic breast augmentation in patients under 18, silicone under 22. Best to check with a board certified plastic surgeon in your area about your individual case.

18 to give consent: Possibly younger if you are an emancipated minor. However you list your age as 30 so I do not see this as being a problem. If you are asking are you young enough to have a facelift, probably not. If you are asking are you young enough to have a nose job, probably yes. Maturity and legal age of consent do not necessarily go hand in hand.

Consent/development: Need to be 18 go consent. Some procedures (nose) should be completed after cessation of growth. Others (protruding ears) are done much younger for psychological reasons.
