Could there be a "right" age to pursue plastic surgery?

Depends...: ...On the operation. Women in their 20-30's are commonly asking about breast augmentation. Those in their 30-40's are commonly asking about tummy tucks (witch hazel). 40's and 50's - blepharoplasty and facelift. So - if you are healthy, and starting to notice a feature you don't like, go see your local board certified plastic surgeon for a consult.

Plastic v cosmetic: There is a great amount of variation in the types of procedures that plastic surgeons perform that range from congenital to acquired conditions as well as functional/reconstructive procedures. Given this range, some even consider in utero repair of fetal cleft lip (experimental) and up to 90 years of age. I believe you meant, cosmetic plastic procedure performed after maturity & age of consent-18.

Depends on Situation: Plastic surgery is a vast field that serves patients as young as neonates all the way up to the geriatric age group. Exactly what the “right” age is to proceed with a specific operation, may depend on exactly what operation is planned. There are some operations best done in childhood and there are some best done after physical “maturity” has been reached.

It depends: Plastic surgeons perform procedures at almost every stage of life. It depends on which procedure you are seeking. A consultation would help determine if you are a good candidate. Age is often not a hinderance.

Yes: Yes. The right age is when you have a problem that concerns you. See a facial plastic surgeon for consultation.
