Bone smashing

Bone smashing is the practice of repeatedly striking your own facial bones — usually the cheekbones, jaw or brow — in the belief that the healing response will leave them denser or more defined. The theory borrows Wolff's law, which says bone adapts to load, and applies it to blunt trauma, which is not load. What a struck facial bone actually does is bruise, swell, and in the worse cases fracture, and the face people see in a before-and-after four days later is a swollen face. The documented outcomes are nerve damage, chronic pain, asymmetric healing, sinus injury and fractures that need fixing surgically. There is no clinical literature supporting any aesthetic benefit, because no ethics board would approve the study. If you want the measurement rather than the trend, the free tools here measure a jaw and a cheekbone in seconds.
