The aging process begins at the skeletal level, where facial bones gradually lose density and volume. This creates less structural support for overlying soft tissues. The orbital rim becomes less prominent, cheekbones lose projection, and the jawline may appear less defined.
Facial fat exists in distinct compartments that age independently. Some areas lose volume significantly, while others may gain fat in less desirable locations. This redistribution creates an imbalanced appearance where youthful fullness disappears from areas that need it most.
The dermis loses approximately 1% of its collagen annually in the mid-20s. Collagen fibers become fragmented and less organized, while elastin fibers responsible for skin bounce-back degrade significantly.
