Bonesmashing Does Not Work
Wolff's Law, periosteum, microfractures, and why hitting your face is not a reliable way to build bone structure
Wolff's Law, periosteum, microfractures, and why hitting your face is not a reliable way to build bone structure
Main point
Bonesmashing borrows real biology, but it does not control the biology it is trying to use
The gap between "bone can remodel" and "hitting your face gives aesthetic bone growth" is where the cope lives
Every bonesmashing argument eventually becomes the same 4 lines:
The usual argument
- "bone adapts to stress"
- "microfractures heal stronger"
- "the periosteum can make new bone"
- "fighters have thicker faces/brow ridges"
All of those are built around real concepts
The problem is the jump from those concepts to the actual method:
hit your facial bones repeatedly -> create useful microdamage -> activate periosteum -> build new bone outward -> get better cheekbones/chin/jawline
That full chain is the part that has not been proven
I actually think the periosteum argument is the strongest version of the pro-bonesmashing case
It just still does not get you where people want it to go
This thread is not "bones are dead and cannot change"
That is false
Bone is alive
It remodels, adapts, heals, resorbs, forms callus, responds to hormones, responds to mechanical loading, and changes during growth
The point is simpler:
Trauma is not the same thing as controlled adaptation
Bonesmashing is not orthodontics, not distraction osteogenesis, not lifting, and not surgery
It is self-inflicted blunt trauma to the face
Claim vs reality
- Claim: impact makes bone adapt outward
- Reality: controlled loading can adapt bone; uncontrolled trauma can also just damage tissue
- Claim: periosteum = free bone growth
- Reality: periosteal reaction is often a sign of irritation/pathology, not a cosmetic plan
- Claim: before/afters prove it
- Reality: photos without imaging and controls are weak evidence
TL;DR
- Wolff's Law is real: it does not say random blunt trauma grows a better face
- The periosteum is real: it helps with growth/repair, that is not the same thing as a DIY cheekbone implant
- Fracture callus is real: callus is injury repair, not aesthetic contouring
- Before/afters are not enough: no CT/CBCT, no standardized camera, different lighting/BF/age/posture = weak evidence
- Most "gains" can be explained without bone growth: edema, scar tissue, inflammation, skin thickening, beard, lower body fat, jaw jutting, puberty, photo selection
- The risk is real anatomy: infraorbital nerve, mental nerve, teeth, TMJ, orbit, sinuses, nose, malocclusion, chronic pain, asymmetry
- Best case: tiny, irregular, unpredictable tissue/bone response that may not even look good
- Worst case: numbness, asymmetry, fracture, dental damage, eye problems, TMJ issues, or surgery to fix the damage
- Verdict: real biology, bad application
Fast rating
- Direct proof of aesthetic bone gain: 0/10
- Biological plausibility: 3/10, trauma can change tissue, that is not the same as useful aesthetic growth
- Control/predictability: 1/10
- Risk/reward: bad enough that I would not call it hardmaxxing, I would call it gambling with facial trauma
Evidence ladder
Bonesmashing is mostly living in the first two levels
- Weakest: "I think I look different"
- Still weak: bathroom before/after with different lighting or BF%
- Better: same lens, same distance, same lighting, same posture, weight/BF disclosed
- Actually relevant: CT/CBCT showing bone change in the target region
- Strong: multiple cases, measurements, timeline, adverse effects, and controls

Read section 3, section 9, and the final verdict, that is basically the whole argument
01 / What bonesmashing is actually claiming
The bonesmashing claim is not just "bone can change"
Nobody serious denies that
The claim is much stronger:
A person can repeatedly strike parts of the face hard enough to create useful microdamage, but not hard enough to cause bad damage, and the healing response will add visible bone in the exact places needed for better aesthetics
That claim has many hidden assumptions
For bonesmashing to work as advertised, all of this has to happen:
- The force has to reach the target bone instead of mostly damaging soft tissue
- The force has to be strong enough to stimulate bone response
- The force has to be weak enough to avoid real fracture, nerve injury, dental injury, orbital injury, TMJ problems, etc
- The body has to respond by adding tissue outward, not just repairing back to baseline
- The added tissue has to stay after swelling goes down
- The change has to be symmetrical
- The shape has to be aesthetic instead of lumpy, irregular, or recessed
- The effect has to be large enough to matter in photos and real life
That is the entire issue
It is not enough to say "periosteum exists" or "bone remodels"
You have to prove the whole chain
So far, the chain is not proven
02 / Adaptation vs damage
This is the main distinction
Adaptive loading is a repeated mechanical signal the bone can tolerate and respond to
Examples:
- walking/running loading the tibia
- resistance training loading the skeleton through muscle and joints
- chewing loading the jaw through normal function
- orthodontics applying controlled force through teeth/periodontal ligament
- palatal expansion applying force through an appliance/suture system
- distraction osteogenesis after a planned osteotomy
Damage is when force exceeds what the tissue can handle
Examples:
- contusion
- hematoma
- microdamage accumulation
- stress reaction
- fracture
- nerve irritation
- scar tissue
- malunion
Bonesmashing tries to act like the second category will behave like the first category
That is the mistake
A heavy impact is not automatically a stronger growth signal, sometimes it is just damage
One hard hit is not equal to thousands of clean mechanical cycles
Hitting your chin is not "chin training" in the same way hitting your bicep with a hammer is not arm day
03 / Mechanostat: the part most people skip
Bone adaptation is better understood through the mechanostat idea
Basic version:
- Too little strain: bone can be lost
- Normal strain: bone is maintained
- High but tolerable strain: bone may adapt
- Too much strain: damage, repair, stress injury, fracture
Bonesmashing assumes:
more force = more bone
Wrong
Bone is not that simple
The signal that tends to matter is not just peak force
It is:
- magnitude
- frequency
- direction
- duration
- rest
- tissue context
- age/hormones/nutrition
- whether the load is functional or traumatic
Bonesmashing fails most of this:
- low frequency compared to real cyclic loading
- random force direction
- high peak impact
- poor control
- no measurement
- soft tissue absorbs a lot of the blow
- no way to know whether you are in adaptation zone or damage zone
This is why "just hit bone until it grows" is broscience
It is not high-IQ hardmaxxing, it is guessing
04 / Wolff's Law, properly understood
Wolff's Law is usually summarized as:
bone adapts to the loads placed on it
True
But users turn it into:
if I hit my face, my face will grow where I hit it
That is not what Wolff's Law proves
Wolff's Law supports the general idea that bone is mechanically responsive
It does not prove that external blunt trauma creates useful aesthetic growth
Good mechanical loading usually has:
- repetition
- consistent direction
- tolerable strain
- progressive exposure
- time to recover
- functional tissue pathway
Bonesmashing has:
- impact
- compression
- pain
- inflammation
- random vectors
- no measurement
- no feedback except swelling and soreness
That is why comparing bonesmashing to orthodontics or exercise is weak
Orthodontics is months of controlled force through a specialized ligament
Exercise is repeated force through muscles, tendons, joints, and bone
Distraction osteogenesis is a surgical cut plus gradual controlled separation
Bonesmashing is blunt trauma
These are not the same biological situation
05 / The periosteum cope
The periosteum is a membrane around bone
It is vascular, innervated, and involved in appositional growth and fracture repair
It can contribute osteogenic cells
That part is true
The cope is this:
periosteum can form bone -> therefore hitting periosteum will form aesthetic bone exactly where I want
That does not follow
Periosteal reaction is not automatically a good thing
It can happen with:
- trauma
- infection
- inflammation
- tumors
- systemic disease
- stress injury
When periosteal new bone shows up on imaging, doctors do not think:
nice, bro got free zygos
They think:
what is irritating this bone?
Even if trauma causes some periosteal bone formation, it can be:
- irregular
- painful
- asymmetrical
- partially reabsorbed
- mixed with scar tissue
- too small to matter aesthetically
- in the wrong shape
The periosteum proves the body repairs and reacts
It does not prove DIY facial sculpting
06 / The microfracture
Another common line:
fractures heal with callus, so microfractures should add bone
Again, half true, bad conclusion
Fracture callus is repair
It is the body trying to restore mechanical integrity after injury
Callus is not a planned aesthetic implant
For fracture healing to go well, you need:
- blood supply
- alignment
- stability
- proper mechanical environment
- time
- no infection
- monitoring if serious
If healing goes badly, you can get:
- malunion
- nonunion
- deformity
- pain
- asymmetry
- loss of function
This matters more in the face because millimeters matter
A small mandibular issue can change bite
A small orbital issue can change eye position or eye movement
A small nerve injury can leave numbness
So the idea of "useful microfractures" is the fantasy part
The person doing bonesmashing has no way to know if he created:
- nothing
- soft tissue swelling
- hematoma
- bone bruise
- microdamage
- real fracture
- nerve trauma
- dental trauma
- scar tissue
Without imaging, it is all mirror science
07 / The fighter argument
"Fighters have strong faces because they get hit"
This sounds good until you think for 30 seconds
1. Selection bias
People with robust bones, thicker necks, better frames, better jaws, and better durability are more likely to survive in combat sports
You are looking at survivors
2. Survivorship bias
The fragile ones get injured, quit, or never reach the level where you notice them
3. Soft tissue
A lot of the "fighter face" look can be:
- scar tissue
- thickened skin
- broken/deviated nose
- swelling
- masseter/neck development
- low body fat
- androgenic baseline
4. Trauma is not symmetry
If face hits improved aesthetics, older fighters would become more symmetrical and model-tier over time
Reality is usually:
- nose deviation
- cuts
- orbital injuries
- dental damage
- asymmetry
- concussions
- scar tissue
So no, fighters are not a clean proof of bonesmashing
08 / Why the results can look real
This is the section most defenders skip
I am not saying every person posting results is lying
I am saying the evidence is extremely easy to fool yourself with
Things that can look like bone gain:
- edema
- hematoma
- chronic inflammation
- fibrosis
- skin thickening
- different lighting
- different lens
- different distance
- different head posture
- jaw jutting
- lower body fat
- higher body fat in certain areas
- water/salt/carb changes
- pump after training
- beard/stubble
- haircut
- puberty
- normal facial maturation
- orthodontics
- fillers
- surgery
- photo selection
The worst evidence is the classic:
16 year old before pic vs 19 year old after pic, different lighting, different body fat, different camera, different facial hair, claims bonesmashing did it
That is not proof
That is a story attached to a transformation
Also, swelling can be convincing
If you hit the chin and it swells, your chin can look more projected
If you irritate cheek tissue, the midface can look fuller
If scar tissue forms, it can feel harder
But none of this proves organized bone growth
09 / Risk map by facial region
Chin
- mental nerve irritation
- lower lip/chin numbness
- lower incisor trauma
- asymmetrical swelling
- false projection from edema
Mandibular body
- inferior alveolar nerve
- tooth roots
- mandibular canal
- fracture risk
- malocclusion
- neuropathic pain
Gonial angle
- angle fractures can be complicated
- third molars can be involved
- bite changes
- TMJ/masticatory muscle pain
- asymmetry if one side responds differently
Zygomatic / cheekbone area
- infraorbital nerve
- maxillary sinus
- orbital rim/floor nearby
- malar asymmetry
- trismus if zygomatic arch is affected
Infraorbital area
- diplopia
- orbital floor injury
- enophthalmos
- V2 numbness
- eye injury
This is probably one of the dumbest areas to experiment on
Nose / maxilla
- nosebleeds
- septal hematoma
- septal deviation
- upper tooth trauma
- sinus issues
- midface fracture patterns in serious trauma
Forehead
- hematoma
- frontal sinus issues
- scarring
- headache
- concussion risk if impact is severe
Temporal area
- superficial vessels
- pain
- near masticatory muscles/TMJ system
- almost no sane aesthetic reason to traumatize it
The face is not just bone
It is nerves, teeth, eyes, sinuses, vessels, joints, muscles, and skin packed together
10 / What really changes facial structure
If you want actual structural change, there are real ways
They are just not free cope
- Genioplasty: changes chin position/shape through planned bone movement
- Implants: chin, jaw, malar, infraorbital, custom designs, planned in millimeters
- Orthognathic surgery: changes maxilla/mandible relationship when indicated
- Palatal expansion/MARPE/SARPE: depends on age, suture maturation, anatomy, and professional planning
- Orthodontics: controlled movement of teeth and alveolar bone
- Distraction osteogenesis: new bone through osteotomy plus gradual controlled distraction
- Fillers: soft tissue contour change, not bone, but at least measurable and reversible in many cases
- Leanness/beard/hair/neck/posture: huge effect on perception without pretending to grow bone
Notice the pattern
Real structural methods have:
- planning
- imaging
- millimeter control
- known anatomy
- follow-up
- complication management
Bonesmashing has:
- mirror
- hand
- pain tolerance
- swelling
- hope
11 / The strongest possible pro-bonesmashing argument
To be fair, here is the best version of the pro argument:
Chronic mechanical irritation can sometimes cause periosteal reaction, subperiosteal hematoma can sometimes ossify, fracture repair can create callus, and the face is not completely biologically static, therefore, repeated trauma might cause some local tissue or bone change in some people
I can accept that as theoretically possible
But that is still not enough
Because the useful claim is not:
trauma can change tissue
Everyone knows trauma can change tissue
The useful claim is:
bonesmashing can reliably improve facial aesthetics with acceptable risk
That is the claim that fails
Even under the strongest pro-bonesmashing interpretation, you still have:
- no validated dose
- no validated frequency
- no validated force
- no validated target area
- no predictable symmetry
- no way to separate bone from scar/swelling
- no serious adverse event rate
- no CT/CBCT evidence base
possible tissue response does not equal useful looksmax
12 / Final verdict
Bonesmashing is not completely made out of nothing
It borrows real words:
- Wolff's Law
- mechanotransduction
- periosteum
- osteoblasts
- microdamage
- fracture callus
- bone remodeling
But it uses those words badly
The actual evidence points to this:
- Bone responds to controlled loading
- Facial bones can change through growth, dental forces, surgery, disease, and controlled medical procedures
- Trauma can create swelling, scar tissue, irregular repair, pain, fracture, and nerve issues
- There is no good direct evidence that bonesmashing creates aesthetic bone gains
- There is no safe protocol
So my final take:
Bonesmashing is broscience with anatomy-risk attached
Not because bone cannot change
Because the method does not control the change
If someone wants to prove otherwise, the path is simple:
- show CT/CBCT before and after
- show standardized photos
- show measurements
- control body fat, age, camera, lighting, posture, fillers, orthodontics, surgery
- track adverse effects
Until then, it is an anecdotal self-injury trend with scientific vocabulary
13 / Common replies
"My chin got wider though"
Maybe
But the question is wider from what? Bone, swelling, scar tissue, lower BF revealing shape, jaw posture, lens distance, facial hair, puberty, or something else? Without imaging you do not know
"CT is too high of a standard"
Not if the claim is bone growth
If the claim is about bone, bone imaging is the normal standard
"Surgery has risks too"
Correct
But surgery has planning, imaging, sterile technique, fixation, consent, follow-up, and a surgeon who can manage complications
Bonesmashing has none of that
"But periosteal hematomas can ossify"
Yes, sometimes
That supports "trauma can cause weird tissue/bone reactions"
It does not support "I can make my cheekbones better by hitting them"
"So you think it is impossible?"
No
I think the useful claim has not been shown
Trauma causing some change is possible
Trauma reliably improving facial aesthetics is the part that lacks proof
"Then why do some before/afters look convincing?"
Because faces are easy to fraud unintentionally, lighting, body fat, lens, head tilt, beard, age, and photo selection can all move the needle
