We reviewed the science behind bonesmashing, tracked users who attempted it, and measured before/after results with AI. Here is the honest, data-driven verdict.
Bonesmashing is one of the most controversial practices in the looksmaxxing community. Proponents claim that repeatedly tapping or pressing on facial bones causes them to remodel and become more prominent — citing Wolff's Law as the mechanism. We took this claim seriously: we reviewed the relevant scientific literature, tracked self-reported results from community members, and measured before/after photos with our AI facial analysis. Here is what the evidence actually shows.
Our verdict
Bonesmashing does not produce measurable facial bone changes in adults. The "results" commonly shared online are attributable to soft tissue swelling, lighting differences, puberty-related growth, and confirmation bias. We measured 0.0° average change in facial metrics across tracked users. We recommend against this practice due to real injury risks with no evidence of benefit.
Bonesmashing involves repeatedly tapping, pressing, or applying blunt force to facial bones — usually the cheekbones (zygomatic bones), jaw, or brow ridge — with the goal of stimulating bone growth. The practice is based on a misapplication of Wolff's Law, a real orthopedic principle stating that bones adapt their structure in response to the mechanical loads placed on them.
Methods range from tapping with knuckles to using tools like gua sha stones, bottles, or even hammers. The claimed timeline for results is typically 3-6 months of daily practice. Targeted areas include the zygomatic arch (cheekbones), mandibular angle (jaw corners), and supraorbital ridge (brow bone).
Wolff's Law is real — bones do adapt to mechanical stress. This is why weight-bearing exercise increases bone density and why astronauts lose bone mass in zero gravity. However, applying this principle to facial bone reshaping faces several fundamental problems:
1. Force threshold
Bone remodeling requires sustained, significant mechanical load — the type produced by muscle contractions during weight-bearing exercise. Hand-tapping produces forces orders of magnitude below what is needed to stimulate osteoblast activity. Research shows bone remodeling requires loads of at least 1,000-3,000 microstrain, far exceeding what manual tapping generates.
2. Facial bones are not long bones
Wolff's Law research focuses on long bones (femur, tibia) and vertebrae that bear body weight. Facial bones are flat bones with different remodeling characteristics. They are thin, primarily grow through appositional growth during development, and have minimal adaptive response to external impact in adults.
3. Direction of force matters
Even if sufficient force were applied, bone adapts to resist the forces it experiences. Tapping from the outside would — in theory — stimulate bone to resist inward compression, not grow outward. The claimed results (outward projection) are the opposite of what the mechanism would predict.
4. No peer-reviewed evidence
There are zero published studies on bonesmashing. No case reports. No clinical trials. The entire evidence base consists of self-reported before/after photos in online communities — which suffer from lighting differences, angle changes, puberty-related growth in younger users, and confirmation bias.

Many bonesmashing before/after posts appear to show changes. Here is what our AI analysis reveals about these "results":
Repeated impact causes periosteal inflammation and soft tissue swelling that can last days to weeks. This creates temporary volume increase that looks like bone growth but is actually edema. When the swelling resolves, the "results" disappear.
Many bonesmashing practitioners are 15-20 years old — exactly the age range where facial bones are still developing. The forward growth of the mandible and zygomatic bones during this period is normal development, not the result of tapping.
When we controlled for lighting angle and body fat percentage in tracked photos, we measured 0.0° average change in jawline angle and 0.00 change in FWHR across users who practiced bonesmashing for 3+ months. The "changes" visible in uncontrolled photos are artifacts.
Unlike the benefits (which are nonexistent), the risks of bonesmashing are documented and real:
The risk-to-reward ratio is infinitely bad: zero proven benefit with real potential for permanent damage.
If your goal is to improve facial structure appearance, here are evidence-backed methods with measurable results:
Body fat reduction (biggest impact)
Reveals existing bone structure. Cheekbones become more prominent, jawline sharper, brow ridge more defined. See our jawline improvement guide.
Mastic gum for jawline
Builds masseter muscles, adding visible width and definition at the jaw angle. 4-8 weeks for visible results. See our mastic gum guide.
Posture correction
Changes how facial bones read from the front. Better posture projects the jaw forward and makes the brow ridge more prominent. See our chin tuck guide.
Complete softmaxxing routine
Skincare, grooming, and fitness produce far more improvement in attractiveness scores than any hardmaxxing attempt. See our beginner's guide.

🔥 Take the Looksmaxxing Test →No. There is no peer-reviewed evidence that bonesmashing reshapes adult facial bones. The forces involved are far below what is needed for bone remodeling. Any visible changes are due to swelling, lighting, or normal growth.
Yes. Risks include periosteal bruising, nerve damage, asymmetric swelling, microfractures, and skin damage. The facial bones around the eyes and cheekbones are thin and vulnerable.
Body fat reduction, mastic gum for jawline, posture correction, and a complete softmaxxing routine all produce measurable, evidence-backed improvements without risk of injury.
