Mewing and 'looksmaxxing'
Tongue posture, 'bonesmashing' and the online self-improvement subculture
'Looksmaxxing' spread from incel forums to TikTok and YouTube, where it is aimed at teenage boys and young men; a 2026 social-listening study measured tens of millions of reach for 'bonesmashing' alone and a 5,000 per cent rise in Google searches for it in a year.
Search interest: about 1,800 searches a month in Singapore for “mewing” (Ahrefs, October 2026).
Mewing does nothing to an adult face; bonesmashing breaks it; and the real harm is a rating system that teaches boys their face is a score. A doctor's job here is to recognise distress, not to operate on it.

Does Mewing and 'looksmaxxing' work?
Caution. Mewing does nothing to an adult face; bonesmashing breaks it; and the real harm is a rating system that teaches boys their face is a score. A doctor's job here is to recognise distress, not to operate on it. Oral surgeons described mewing in 2019 as social media's alternative to orthognathic surgery, without evidence that it changes adult facial structure.

What it is
A subculture that ranks male faces and prescribes fixes. 'Softmaxxing' is grooming, skincare and gym. 'Mewing' is pressing the tongue to the palate to reshape the jaw. 'Hardmaxxing' includes jaw and chin implants, steroids, 'starvemaxxing' and 'bonesmashing' — striking the face with hard objects in the belief that bone remodels thicker.
How it works
Tongue posture is part of orofacial myofunctional therapy, which has a legitimate role in growing children with mouth-breathing or swallowing problems. In adults the facial skeleton is fixed; no amount of tongue pressure moves the maxilla, and no amount of impact builds cheekbones. Bone responds to fracture by healing, not by growing a sharper edge. The content works by constant self-rating, face-scoring apps and a vocabulary that turns ordinary variation into defects.
What the evidence says
Oral surgeons described mewing in 2019 as social media's alternative to orthognathic surgery, without evidence that it changes adult facial structure. A 2026 cross-sectional analysis of looksmaxxing content found 'bonesmashing' posts were about 98 per cent male, that tutorial posts earned higher engagement, and that the discourse normalised self-injury. Letters in maxillofacial and facial plastic surgery journals report young men presenting with facial injuries and requesting surgery on the basis of forum advice. Appearance-focused content is linked to body dysmorphic symptoms in adolescent boys. There is no clinical trial of any looksmaxxing practice.

What the studies show
- cohort
Social-listening analysis found large, overwhelmingly male engagement with bonesmashing and mewing content, higher engagement for tutorials, and themes normalising self-injury.

- review
Facial plastic surgeons framed looksmaxxing as a spectrum from grooming to self-harm and set out how to recognise and counsel affected patients.

- review
Maxillofacial surgeons warned that bonesmashing produces fractures and soft-tissue injury rather than any cosmetic change.

Who it suits
Suits
Nobody, as a programme. The sensible half is sunscreen, sleep, exercise and not smoking, which need no subculture.
Not for
Teenagers and young men scoring their faces with apps; anyone considering impact, DIY injection or surgery on forum advice; anyone with features of body dysmorphic disorder, which a surgeon should screen for before operating.
Alternatives
The two reviewed treatments most often weighed against Mewing and 'looksmaxxing', on the same standard.
| Mewing and 'looksmaxxing' | HIFU | Monopolar radiofrequency | |
|---|---|---|---|
| Verdict | Caution | Vetted | Vetted |
| What it is | A subculture that ranks male faces and prescribes fixes. | High-intensity focused ultrasound delivers heat to precise points at set depths — commonly 1.5, 3.0 and 4.5 mm — creating coagulation points in the dermis and the SMAS layer that contract and stimulate collagen over months. | A single large electrode delivers radiofrequency energy that travels through the tissue to a grounding pad, heating the dermis and subcutaneous layer volumetrically. |
| Evidence base | 4 PubMed-indexed studies cited below (cohort, review); no systematic review or randomised trial on the claim itself. | 3 PubMed-indexed studies cited below, including systematic reviews. | 3 PubMed-indexed studies cited below, including systematic reviews. |
| Suits | Nobody, as a programme. The sensible half is sunscreen, sleep, exercise and not smoking, which need no subculture. | Mild to moderate laxity with reasonable skin thickness, people who want a structural effect without injectables. | Mild to moderate laxity of the face, eyelids, neck and body; people who prefer a no-needle, no-injectable approach. |
| In one line | Mewing does nothing to an adult face; bonesmashing breaks it; and the real harm is a rating system that teaches boys their face is a score. A doctor's job here is to recognise distress, not to operate on it. | HIFU or radiofrequency is the wrong question — they do not do the same job, which is why 3D Facial Reconstruction uses both. | The device delivers heat; the protocol decides where it goes and in which order. That is the whole difference between tightening and lifting. |
Risks
Facial fractures, dental damage, nerve injury and scarring from bonesmashing; steroid and stimulant harm; eating-disorder behaviour; and a documented pipeline from skincare content to misogynist communities and self-harm.
In Singapore
Not a treatment and not regulated. In Singapore, anyone under 18 requesting aesthetic procedures needs parental consent, and doctors are expected to decline treatment driven by body dysmorphic disorder; our clinics screen for it and refer to mental-health support when needed.
