Facelifts and other wrinkle-reducing procedures have long been sought by people wanting to ward off the signs of aging, but new research suggests that it takes more than tightening loose skin to restore a youthful look. A study by physicians at the University of Rochester Medical Center indicates that significant changes in facial bones – particularly the jaw bone – occur as people age and contribute to an aging appearance. …
This loss of bony volume may contribute sagging facial skin, decreased chin projection, and loss of jaw-line definition. As jaw volume decreases, soft tissue of the lower face has less support, resulting in a softer, oval appearance to the lower face and sagging skin, which also affects the aging appearance of the neck.
“Physicians have long been taught that facial aging is caused by soft tissue descent and loss of elasticity,” Langstein said. “Though we have always known that bones change over time, until now, the extent to which it causes an aged appearance was not appreciated.”
… “The future of facial cosmetic procedures to restore a youthful look may include methods to suspend soft tissue – such as chin and cheek implants – to rebuild the structure that time has worn away, in addition to lifting and reducing excess skin,” Shaw said.
