Facial development refers to the process by which the human face forms and matures from early embryonic stages through childhood. This process involves the growth and fusion of various facial structures, including the maxilla, mandible, and nasal bones. Genetic factors and environmental influences play significant roles in shaping the face. During infancy and childhood, the face continues to grow and change, with features becoming more defined. The development of facial muscles and the alignment of teeth also contribute to the overall appearance. Proper nutrition and health during these stages are essential for optimal facial development.
