Please explain the nose growth process of a teen and how the nose changes from 16 year old to when an girl turns 19?

Nose growth stabilizes at about age 15-16. It has reached its adult size by then. It is unlikely to change very much over the next few years. For this reason, rhinoplasty surgery is very common at this age. It is unlikely that you will grow into a nose if it significantly out of proportion to your face after this age. Discuss this matter with your parents and seek consultation from a board certified plastic surgeon. Best wishes.

For most females the growth process is complete by 16. As musculoskeletal growth comes to a halt, the nasal growth does as well.Kenneth Hughes, MDLos Angeles, CA

When it comes to girls,
the nose typically stops growing at 15-16 years old (boys is usually 16-17 years
old). Patients at this age should be
able to move forward with Rhinoplasty surgery, as long as they have their
parents consent. How the jaw and the
remainder of the face evolve threw the growth process is a very individual
process and cannot be precisely predicted. I hope this helps!
