Facial growth refers to the changes in the structure and appearance of the face as a person ages. This process is influenced by genetics, nutrition, and environmental factors. During childhood and adolescence, the bones and soft tissues of the face develop, leading to the distinct features seen in adults. In adults, facial growth continues but at a slower rate. Changes may include the gradual loss of fat, which can lead to a more angular appearance, and the development of wrinkles due to reduced skin elasticity. Factors like sun exposure and smoking can accelerate these changes, affecting overall facial aesthetics.
