There’s no “best” age for rhinoplasty. Rhinoplasty can be performed on teenagers once their facial bones and cartilage have stopped growing, which coincides with when they stop growing in height. That’s typically at about age 15 for girls and 18 for boys. After that, rhinoplasty can be performed with excellent cosmetic results on adults of any age. Cosmetic changes to the nose can be beneficial in old age when the nose develops in a form that is out of harmony with other facial features, growing longer or with a downward-hooked end, for example.
