I’ve been looking into the biomechanics behind bonesmashing, and the more precise question isn’t “does hitting your face make your bones grow?”
It’s whether controlled, low-magnitude mechanical vibration can influence facial bone remodeling without deliberately smashing, fracturing or injuring anything.
I’m not claiming this works. I’m trying to separate what has actually been shown from what people on these forums have simply repeated until it started sounding like science.
1. Bone responds to mechanical loading
Bone is not dead concrete. Osteocytes act as mechanosensors and respond to mechanical deformation and fluid movement inside bone tissue.
They can then influence signaling pathways involved in osteoblast and osteoclast activity.
In simple terms:
mechanical stimulus → osteocyte signaling → possible changes in bone remodeling
That general process is well established.
Bone also continues remodeling throughout adulthood. But this is where people usually make the leap: the fact that bone remodels does not mean that any random external stimulus will reshape your face in a useful or visible way.
Sources:
2. Human mandibular cells respond to vibration in vitro
This is one of the more relevant findings, but it is also one of the easiest to exaggerate.
Some studies have exposed human mandibular osteoblasts to mechanical vibration.
One study tested frequencies including:
30 / 60 / 90 / 120 Hz
for 30 minutes.
The cells showed changes in osteogenic activity and Wnt-related signaling under those experimental conditions.
That means the cells responded to vibration in a dish. It does not mean that vibrating your face will make your jaw wider, your cheekbones sharper or your facial projection better.
Cell culture is useful for identifying possible mechanisms. It is not a before-and-after facial transformation study.

3. Craniofacial vibration has also been studied in animals
Animal studies are more relevant than isolated cells because they involve living tissue, blood supply and an actual organism.
They are still not human trials.
One study in rats applied low-magnitude, high-frequency vibration to the craniofacial region.
The protocol was approximately:
30 Hz
0.3 cN
20 min/day
5 days/week
for 1–2 months.
The researchers used micro-CT to assess craniofacial bone parameters.
They reported changes in measures such as bone volume, density and craniofacial dimensions under those specific study conditions.

Other animal research has examined 30 Hz vibration during healing of cranial bone defects and reported greater bone regeneration than in controls.
That is interesting if you care about bone repair. It is not proof that vibration enlarges normal, intact facial bones in healthy adults.
Source:
So the honest summary is:
mechanical stimulation → measurable biological responses in some experimental settings
human mandibular cells → response to vibration in vitro
craniofacial bone → response to vibration in some animal models
That is not the same thing as “buy a massage gun and grow cheekbones.”
4. The major missing evidence
We still do not have good evidence showing:
controlled external vibration → increased facial bone size or projection in healthy adult humans
That is the part that actually matters.
There is a huge difference between:
“vibration can influence cellular activity or bone remodeling markers”
and:
“vibration makes a person’s zygomatic bones more prominent.”
The first has some support in laboratory and animal research.
The second has not been established by convincing clinical evidence.
A real human study would need an appropriate control group, a defined protocol, enough follow-up time and quantitative imaging capable of detecting actual changes in facial bone morphology.
Not selfies. Not “my face feels harder.” Not a guy claiming his cheekbones grew because he hit them every night for six months.
5. What about the 0.8–1.1 MPa claims?
This is where a lot of bonesmashing content starts pretending that a complicated biological system has one magic number.
I’ve seen claims that:
0.8–1.1 MPa = optimal bone growth
and that massage guns can supposedly reach this range.
I’m not aware of evidence establishing that pressure range as a universal target for facial bone growth, especially in healthy adult humans.
Bone does not respond to one number in isolation. The response depends on things like:
- frequency
- amplitude
- strain
- loading pattern
- duration
- location
- tissue geometry
- biological state
And “pressure from the device,” “pressure at the skin” and “strain experienced by the bone” are not automatically the same thing.
So no, I would not treat 0.8–1.1 MPa as an established facial bone growth sweet spot.
Likewise, claims such as:
“X kg of force = X mm of zygomatic growth”
or:
“this exact protocol will produce 1–3 mm”
are not scientific predictions unless they come from direct experiments with validated imaging and proper controls.
I have not found evidence supporting those specific numbers.
6. What would a stronger study look like?
The question is testable. The internet just seems more interested in arguing over anecdotes than running the obvious experiment.
For example, mature animals could be assigned to groups such as:
Control
Low-frequency vibration
Medium-frequency vibration
High-frequency vibration
Amplitude and exposure time could also be varied.
Researchers could use micro-CT before and after treatment to measure:
- cortical thickness
- bone volume
- bone density
- zygomatic dimensions
- mandibular dimensions
- cranial dimensions
- suture morphology
A properly designed study could show whether there is a reproducible dose-response relationship.
It would also need to distinguish between:
effects limited to healing or repair
changes in bone density or microarchitecture
and:
a measurable change in facial bone morphology
Those are not interchangeable outcomes.
More bone density does not automatically mean a more projected face. A cellular response does not automatically mean a visible anatomical change.
7. Why animal findings may not translate directly to humans
Animal results do not automatically predict what happens in humans.
Rats differ from humans in anatomy, facial proportions, bone turnover, tissue thickness and mechanical loading patterns.
Even if vibration increases bone formation or density in an animal model, that does not mean the new bone will form in a direction that improves facial projection.
You could increase density or alter microarchitecture without producing any meaningful change in the external shape of the face.
That is why claims about aesthetic facial remodeling require three-dimensional imaging and actual anatomical measurements, not just cellular markers or vague statements about “bone growth.”
8. Vibration and traditional bonesmashing are different hypotheses
These should be treated as separate mechanisms, not as two versions of the same thing.
Traumatic bonesmashing:
Impact → tissue injury → inflammation/hematoma → healing and remodeling
vs.
Controlled vibration:
Low-magnitude cyclic loading → mechanotransduction → possible changes in remodeling activity
Those arrows describe proposed mechanisms, not guaranteed results.
If controlled vibration ever turned out to produce a useful anabolic response, that would not prove that deliberately damaging your face is necessary. It would suggest the opposite: find the lowest effective stimulus and stop pretending that more injury automatically means more growth.
Whether such a stimulus can actually change adult facial morphology is still unknown.
And obviously, “unknown” does not mean “probably works.”
9. What does the evidence actually show?
I’d summarize the current evidence like this:
Bone mechanotransduction: well established as a general biological process Human mandibular osteoblasts responding to vibration: demonstrated in vitro under specific laboratory conditions Craniofacial bone responding to vibration: reported in some animal studies
Controlled vibration changing facial bone morphology in healthy adult humans: not established Controlled vibration producing an aesthetic facial effect: biologically conceivable but unproven
A validated human protocol for increasing zygomatic or mandibular projection: no convincing evidence currently establishes one Claims of guaranteed +1–3 mm facial growth from specific bonesmashing protocols: unsupported by the evidence presented here10. What evidence would actually settle this?
If anyone knows of a study I’ve missed, especially one involving:
healthy adult humans + craniofacial bone + externally applied vibration + quantitative three-dimensional imaging
please post it.
The useful studies would measure actual changes in facial bone morphology, not just cellular markers, short-term biochemical responses or general bone density.
I’d also want to see adverse effects reported. External vibration or impact can affect skin, muscle, nerves, teeth, the temporomandibular joint and other tissues even if it does absolutely nothing to the bone.
I’m not trying to prove that bonesmashing works.
I’m trying to determine whether controlled mechanical stimulation has any demonstrated ability—or merely a theoretical possibility—to produce small, controlled changes in adult facial bone morphology.
Right now, the evidence supports a biological mechanism and some animal findings.
It does not support the confident internet claim that hitting or vibrating your face will reliably give you better cheekbones.
