After the age of 18, the bridge of the nose will not grow any higher, because after the age of 18, the growth and development of the human body is basically completed, and the development of bones and organs has basically been perfected, and the bones and cartilage of the nose have basically stopped growing, so the bridge of the nose will not grow any higher. In the case of a child, the bridge of the nose will gradually increase as the body grows and the bones and cartilages that make up the nasal bones will grow. The shape of the nose is generally in proportion to the development of the facial bones, and the shape of the nose and facial bones and features is highly genetically related. The shape of the nose is also related to race. People in Europe and the United States have a more upright nose, and the facial bones of these countries develop in the same proportion. People in Asian and other Eastern countries have a low nasal bridge, which is consistent with the proportion of flat facial bones.
