Mewing
Mewing.
The technique in 30 seconds
Mewing was popularized by British orthodontist Dr. Mike Mew. The protocol:
- Tongue posture — entire tongue (tip + back) flat against the roof of the mouth, not just the tip
- Lip seal — lips closed, breathing through the nose
- Teeth posture — molars lightly touching, no clenching
- Held 24/7 — including while sleeping, eventually unconsciously
That’s it. No products to buy.
What mewing claims to do
Long-term claims (1–5+ years of consistent practice):
- Wider, more forward-grown maxilla (upper jaw)
- More defined gonial angle (jawline corner)
- Improved nasal breathing
- Reduced double chin appearance
- Better facial proportions over time
Short-term effects (days to months):
- Tighter jawline appearance
- Reduced under-chin softness
- Better posture (head sits more forward)
- Cleaner side profile in photos
What the evidence actually says
Independent peer-reviewed studies on adult mewing are limited. What we have:
- Childhood orthotropics (the parent discipline) has decades of evidence for craniofacial development with proper tongue posture during growth.
- Adult bone remodeling is slow but real — small angular changes are biologically possible over years.
- Postural and muscular changes are immediate and measurable.
What it almost certainly won’t do for adults: dramatically widen your face, eliminate a recessed chin, or replace orthognathic surgery for severe maxillary issues.
How Fazly tracks mewing progress
Take a baseline scan, mew consistently, re-scan every 4–8 weeks. Watch:
- Jawline sub-score — biggest change zone
- Side profile angle (in your detail breakdown)
- Submental fullness (under chin softness)
Most users see a 3–6 point Fazly sub-score lift in the first 90 days. After that, gains slow but compound over years.
Common mewing mistakes
- Pressing only the tongue tip (use the whole tongue)
- Mouth-breathing while “mewing” (defeats the purpose)
- Clenching teeth (creates tension headaches, no benefit)
- Expecting overnight bone changes
- Forgetting that diet and sleep affect facial fullness more than posture in the short term

Jawline Score
A 0–100 measure of jawline definition. Combines gonial angle (corner of the jaw), bigonial width (horizontal jaw breadth), submental softness (under chin), and chin projection. Fazly's jaw model is the highest-correlated sub-score with overall rating.

Looksmaxxing
A self-improvement framework focused on physical appearance — skincare, grooming, posture, fitness, style, and sometimes cosmetic procedures. Has a 'softmaxxing' (low-effort) and 'hardmaxxing' (surgical) wing. Fazly is built for the softmaxxing path.

Canthal Tilt
The angle from your inner eye corner to your outer one. Positive tilt (outer corner higher) reads as more attractive across cultures. Neutral is fine. Negative tilt drags your face score down.
