A complete, evidence-backed approach to controlled mechanical stimulation of bones – What is it, how does it work, and how do you perform it without losing your face?
"Bonesmashing" refers to the use of controlled compression or vibrational force to grow bone via bone remodeling, creating thicker bone mass and an increased prominence of the bone.
Facial bone structure is arguably one of the most dimorphic aspects of the face, and among the most aesthetically important as well. Prominent mandibles, zygomas, and supraorbital ridges are consistently perceived as more attractive. Moreover, the benefits of bone remodeling include its permanence compared to soft tissue modification.
That being said, the face happens to be the most fragile part of our body when it comes to external impacts. The reason behind this tutorial is the absence of adequate information on how to smash bones effectively and safely. Most online guides fall into either of these categories:
Too safe (massage that fails to cross the mechanostat threshold)
Too dangerous (using blunt force like hammering, which may lead to fractures)

Proposed by Julius Wolff in 1892, this principle indicates that bones adapt structurally due to mechanical loading. Loading bone stimulates osteoblasts (bone-building cells) to form a mineralized matrix where pressure occurs. In the absence of loading, bones undergo resorption, effectively breaking down.
It is the physiological mechanism that translates mechanical forces to cell proliferation. Here's how:
Mechanical loading compresses bone cells (osteocytes)
Compressed osteocytes inhibit production of sclerostin, the protein that inhibits bone formation
Wnt/β-catenin signaling pathway is activated when there's no inhibition of production
Signaling activates osteoblasts to multiply and form bone matrices

As mentioned earlier, hydroxyapatite, which constitutes bone minerals, exhibits piezoelectric properties. As a result, compression induces electric potential, leading to negative charge. Negative charge draws calcium ions to the point, accelerating mineral deposition in collagen matrices.

Bone exterior features periosteum, a vascular membrane containing osteoblast precursors. Mechanical loading stimulates preosteoblasts to form new bone layers exteriorly while osteoclasts form bone layers interiorly to prevent excessive weight accumulation. This results in increased bone width and volume with minimal increase in mass.

Chronic traumatic encephalopathy (CTE) is caused by repeated head acceleration (60–90g forces) leading to collisions of brain with skull — as happens in boxing and American football.
Why smashing of jaw bones does NOT lead to CTE:
Temporomandibular Joint (TMJ)
It consists of a cartilage disc, and it is attached to the masseter muscle; it works as a cushioning system that absorbs vibrations within the mandible and not the skull.

Why smashing of jaw bones does NOT lead to CTE:
| Factor | Boxing Impact | Jaw Bonesmashing |
| Head acceleration | 60-90g | ~0g |
| Brain movement | Severe (brain hits skull) | None (brain stationary) |
| Energy dissipation | Direct cranial transmission | TMJ joint + masseter muscle absorb 90% |
| Travel distance | Unrestricted head movement | 10–14mm gun head travel, neck fixes head |
It consists of a cartilage disc, and it is attached to the masseter muscle; it works as a cushioning system that absorbs vibrations within the mandible and not the skull.

The technique allows for unilateral correction. In case one angle of the mandible does not develop properly, stop applying any loading to the stronger side and apply 100% volume to the weaker side.

All training protocols follow Frost's Mechanostat Principle: forces smaller than the threshold result in no change whatsoever; forces above ~10kg carry a danger of fractures and disorganized callus development.
Zone A: Gonion (mandibular angles and chin)
Zone A: Gonion (mandibular angles and chin)
- Training target: widening the jaw and projecting the chin
- Force: 4.0-6.0 kg (similar to pressing down hard on a digital weighing device with your hand)
- Equipment: massage gun, mode 1-2, flat, solid attachment
- Frequency: once every two days (3x per week)
- Duration: 45-60 seconds per side
- Application: straight-on perpendicular pressure
- Training target: facial width and zygomatic prominence
- Force: 2.0-3.5 kg (similar to squeezing a tube of toothpaste)
- Equipment: either massage gun mode 1 or knuckle massager
- Frequency: 2x per week
- Application: bottom-to-top, sideways movement — never apply pressure directly onto cheek tissue
- Important: Zygomatic arch is bone, not soft tissue. Apply the force there.
- Training target: brow rim prominence and orbit framing
- Force: 1.0-1.5 kg (pressing down hard on a door bell switch)
- Equipment: HANDS ONLY — thumb point pressure
- Frequency: 2x per week
- CAUTION: Use of massage guns for supraorbital application is CATEGORICALLY FORBIDDEN. The skull in this region is very thin, and there is the frontal sinus underneath.
Bone remodeling cannot occur within 30 days. It takes 90-120 days (3-4 months) to have fully mineralized the bones.
Remember, these are millimeters of solid cortical bone, not swelling.
| Month | Biological Event | Visual Appearance | Reality Check | |
| 1 | Periosteal edema, lymph influx | Face appears wider | NOT bone. Edema subsides in 5–7 days if you stop | |
| 2 | Osteoid formation (soft collagen matrix) | Visual plateau — looks like nothing is happening | Foundation is being laid. This is normal. | |
| 3 | Mineralization begins |
| Measurable change begins | |
| 4-6 | Continued apposition | Gradual, permanent widening | Cumulative effect becomes visible | |
| 6-12 | Consolidation | Final structural change |
|
Realistic Growth Forecasts (6–12 Months)
| Age | Biological Advantage | Forecast | |
| Teens (14-18) | Active growth plates, peak hormones | 1.5–3.0 mm width increase | |
| Young Adults (19-25) | Growth plates closed but high hormone levels | 0.5–1.5 mm | |
| Adults (25+) | Fully mature skeleton |

Rule 1: No Training Daily
- Bones take 48–72 hours to start their remodeling process. Training daily leads to formation of a pathologic callus that results in deformation of facial structure. Always stick to an every other day routine when remodeling the mandible and a twice weekly routine for cheeks and brow areas.
- New bone matrix needs materials to be built out of. In absence of sufficient nutrition, the mechanism of mechanotransduction is going to have nothing to work with:
- Caloric excess: Bone growth is metabolically costly
- Protein intake: 1.6-2.2g/kg body weight (for collagen matrix creation)
- Calcium: Through dairy, green vegetables or by supplementation
- Vitamin D3: For regulating the deposition of calcium into bone tissue (vital – otherwise calcium does not do its job)
- Immediately halt all training at least for two weeks if you notice one of the following:
- Bruising and formation of hematomas (indicative of vessel damage and excessive pressure)
- Continuous bone pain (a sign of stress fracture development)
- Pain in your teeth/gingiva (bone receives too much pressure)
- TMJ clicking/popping/pain (joint gets overloaded)
The bonesmashing technique is neither a meme nor an orthopedic procedure used for facial enhancement. This process is a real one because it makes use of orthopedic science to change facial features. However, it must be done in a specific way in order to make changes and avoid injury or damage.
