I am 15 years old and my nose is tiny for a guy. Will this change as I go through puberty?

At 15, you are still in the midst of drastic changes to your appearance. You should not feel concerned about your lack of a strong chin or nose, as these will develop over time. As you grow older and your face takes on its adult shape, you can then reevaluate and consider augmenting your nose. However, until then, do not worry and let the development and growth of your facial structure happen.

Thank you for your question. Yes, your nose and facial features will continue to change as you go through puberty. And, yes, there are surgical options to increase the size of your nose when the timing is right and when it is certain that you have matured physically. It may be best to wait a few years until you've gone through puberty before consulting with a board certified plastic surgeon to discuss your concerns and the best rhinoplasty options for you. Best of luck!

At 15 years old, your facial features have not achieved full
adult development. As you have pointed out, the nose’s appearance is closely
connected to other surrounding facial features, such as the chin. A safe and a
conservative approach to treatment may be considered a few years down the road.
I recommend consultation at that time with a Plastic Surgeon certified by the
American Board of Plastic Surgery.- Brian M. Derby, MD, on behalf of James C. Grotting, MD

Thanks for your question.  Yes, your nose will change as you get older.  I would certainly give it a few more years before you make a decision.  

Yes your nose will change during puberty and the cartilage in our nose and ears continue to grow as we get older.   Genetics, however is the most important factor.   If your parents have really small noses then you will as well   Best to you.
