Bonesmashing

Overview

“Bonesmashing” refers to repetitive blunt trauma applied to the jawline, cheekbones, brow, or nose in an attempt to alter facial structure and create a more “masculine” appearance. (1) Methods may include repeated punching, striking with hard objects, or use of hammers. (1)

The practice is rooted in misapplication of Wolff’s law, the principle that bone remodels in response to mechanical stress, despite lack of evidence supporting efficacy. (1)

Potential dermatologic and structural complications

Facial fractures

Repeated blunt trauma may result in fractures involving facial bones, nasal structures, or the orbital region. (2, 3)

Soft tissue injury

Swelling, hematomas, ecchymoses, and chronic soft tissue inflammation may occur. (2, 3)

Nerve injury and chronic pain

Trauma may result in sensory changes, paresthesia, neuropathic pain, or chronic tenderness. (2, 3)

Ocular and orbital injury

Periorbital trauma may increase risk of orbital injury and vision-threatening complications. (2, 3)

Scarring, dyspigmentation, acne

Repeated trauma may contribute to post-inflammatory hyperpigmentation, fibrosis, folliculitis mechanica, or acne vulgaris flares in trauma-prone areas. (4, 5)

Important history questions

• Have you intentionally applied repeated pressure or trauma to facial bones?

• Have you used tools or devices to alter facial structure?

• Do symptoms worsen after online “jaw training” or facial exercises?

• Have you noticed numbness, bruising, swelling, or persistent pain?

Counseling considerations

Dermatologists can counsel patients regarding:

• Lack of evidence supporting structural facial remodeling through blunt trauma.

• Risks of fractures, ocular injury, chronic pain, and scarring.

• Potential for permanent cosmetic deformity.

• Importance of medical evaluation for persistent swelling, vision changes, or neurologic symptoms.
