Bonesmashing (Microtrauma Loading)
Hitting your face does not build bone. It risks fracture, nerve damage, and asymmetry. Do not do this.
Evidence grade D
No credible supporting evidence
Mechanism
Misapplies Wolff's law: bone adapts to repeated mechanical LOADING (compression through use, e.g., chewing), not blunt percussive trauma to the periosteum.

The full read
Wolff's law describes bone remodeling under functional load — think jaw muscles transmitting force through the mandible over years of chewing. Striking the zygomatic or mandibular surface produces soft-tissue swelling (temporarily mistaken for 'growth'), risks fractures, chronic bone bruises, and permanent nerve injury, and has zero documented cases of favorable morphological change. This is the canonical dangerous cope. If you want a stronger-looking jaw: body-fat reduction, chewing load, or consult a maxillofacial specialist.
