The human head never stops growing and changing, according to findings reported by Duke Magazine. While most bones stop growing following puberty, CT scans conducted on 100 men and women demonstrated that the bones of the skull continue to grow and change throughout a person's lifetime.
Subtle modification of facial structure occurs as the cheekbones move backward, the forehead moves forward, and the muscles and skin covering these bones move as well, Duke Magazine explains. The soft tissues of the face lose their support as the facial bones tilt forward. This results in drooping and sagging skin that has cosmetic implications in addition to causing medical concerns. For example, when the tissues surrounding the eyelids droop, vision problems can occur.
