Generally speaking, there is no strict age limit for rhinoplasty, but if you are too old or too young, don't do rhinoplasty. Under normal circumstances, doctors will advise beauty seekers to have rhinoplasty after 18 years old, because the bones will stop developing in adulthood, so the nose will be shaped for a long time after the operation.
About 20 years old is the best period of human health. Whether it is physical function or recovery ability, it is the most golden time, and the postoperative recovery period will be shorter and the recovery will be better.
