Hello, in fact, the bridge of the nose is a soft tissue that generally takes longer to grow than the bones. Theoretically, it is believed that the bridge of the nose is basically finalized when you are seventeen or eighteen years old and will not change much. But you He's only 15, so he should be a little older. Don't give up hope. Of course, even if it no longer grows, there are many ways to change the shape of the nose, such as hyaluronic acid injections, rhinoplasty with prostheses, and some people say it can also be changed through acupuncture, so don't worry, there is always hope as long as you want to change. Hope my answer can help you.
