Your face maintains its youthful contours through a complex interplay of deep and superficial fat compartments, a dense collagen-elastin matrix, and the bony scaffold of the skull. Beginning around age 30, collagen production declines by approximately 1% per year, while existing collagen fibers become cross-linked and rigid, reducing the skin's ability to maintain structure and elasticity.
The facial fat pads, which sit in distinct anatomical compartments, begin to atrophy and descend under the influence of gravity. The malar fat pad in the midface loses volume first, causing the cheeks to flatten and nasolabial folds to deepen. As the buccal and temporal fat pads follow, the temples hollow and the lower face loses its smooth contour.
Simultaneously, the facial skeleton itself undergoes resorption, particularly around the eye sockets, the midface, and the jawline. Studies show that the maxilla recedes and the mandible loses height and projection with age, reducing the structural framework that supports overlying soft tissue. This triple mechanism of fat loss, collagen degradation, and bone resorption creates the compounding volume deficit patients experience.
