Early childhood (birth to ~7-9 years): Most rapid growth happens early. By age 4-5, about 60-80% of adult facial size is reached in many areas (e.g., forehead, orbits). By age 7, craniofacial bones are ~70-90% of adult size. The face is rounder, with "baby fat" (buccal fat) making cheeks fuller and softer.
Pre-pubertal period (~7-12 years in girls, ~9-14 in boys): Slower, steady growth. Sexual dimorphism (differences between boys and girls) begins subtly around age 9.
Puberty/adolescence (onset ~9-12 in girls, ~11-14 in boys; peak ~11-15 in girls, ~14-17 in boys): Major spurt in facial growth. Hormones drive dramatic changes:
Mandible (jaw) grows more than maxilla (upper jaw), especially in boys → longer, more prominent lower face.
Brow ridges, cheekbones, chin, and nose become more pronounced (especially in boys: anterior brow growth, wider jaw, prominent chin).
Cheeks flatten (loss of baby fat), face elongates and widens.
Overall: Boys develop more angular, robust features; girls show subtler changes with rounder or wider faces.
Late adolescence to early adulthood (~16-21+): Growth slows and stabilizes. Males often continue minor changes longer (up to ~21-22), while females finish earlier (~16-18). Bone remodeling continues lifelong but minimally.
Facial growth is influenced by genetics (main factor), nutrition, breathing (nasal vs. mouth breathing affects jaw/maxilla), hormones, and environment. Poor habits (e.g., chronic mouth breathing) can lead to underdeveloped upper jaw or imbalanced proportions. 'break bones kid
