As the body continues to grow, the bridge of the nose is usually shaped around the age of 18. The appearance of the nasal bridge is mainly determined by genetic factors, nutrition level and development speed. Some people think that the nasal cartilage is not completely set before the age of 18, so proper pinching of the nose may have a benign stimulating effect on the nose, but in fact, it is not. Frequent pinching of the nose may affect the normal development of the nasal bone, and in serious cases, the nose may be pinched. In conclusion, the bridge of the nose is mainly determined by genetic factors. If you are not satisfied with your nose shape, you can have orthopedic surgery after the age of 18 to improve the appearance of the nose by surgically filling the nose with autologous tissue or tissue substitutes to elevate the external nose.
