About ALYGN

ALYGN is a free web service that helps you check and manage facial asymmetry on your own. This page explains what we measure and how, the standards behind our content, and what the service cannot do.

What ALYGN is

From a single front-facing photo, ALYGN scores the left-right balance of your face by area, then connects you to corrective exercises for the areas you can work on and to guides that explain the causes. No sign-up is required, and analysis, exercises, and guides are all free.

A mirror only tells you that one side “looks different.” Which area differs, by how much, whether it comes from habits or bone structure, and whether it improved since last month — those need numbers. ALYGN was built to close the gap between those numbers and what to do next.

What we provide

Face balance analysis — from facial reference points in a front-facing photo, we measure four areas (eyes, mouth & jaw, midline, facial width) across 10 metrics. Head rotation is corrected and multiple frames are merged statistically to reduce capture error.

20 corrective exercises — each one, sorted by area, comes with steps, why it works, the muscles involved, common mistakes, signs it is working, and FAQs. A voice-guided follow-along mode and a daily routine matched to your analysis are included.

Face balance guides — articles on the causes of asymmetry, its relationship with the TMJ, chewing, sleep and posture habits, the evidence and limits of facial exercise, and when to see a doctor. They give the background needed to interpret your results and choose what to do next.

How we write content

Evidence first. Guides and exercise explanations are written from review papers in oral and maxillofacial surgery and orthodontics and from public health institutions, and we say so when the evidence is weak. The sources we relied on are listed at the bottom of this page.

No hype. We distinguish functional asymmetry (from muscle habits) from structural asymmetry (from skeletal differences), and state clearly what exercise can and cannot change. We avoid claims like “slims your face” or “fixes your jaw.”

We do not replace medical judgment. Signs that call for a clinic — pain, limited mouth opening, rapid change — are stated throughout the content, and we repeat that a self-check is not a diagnosis.

We revise regularly. Every guide shows its last-updated date, and content is refreshed based on reader questions and new sources. If you spot an error or disagree with a source, tell us via the contact page and we will review it.

Limits and disclaimer

ALYGN is not a medical device and cannot be used for diagnosis or treatment. Results are photo-based estimates; whether you have a TMJ disorder, malocclusion, or skeletal facial asymmetry can only be determined by a clinician’s examination and imaging.

The exercises are general muscle release and strengthening movements. If you have pain or are under TMJ or dental treatment, consult your clinician before starting, and stop immediately if an exercise causes pain.

Who runs ALYGN

ALYGN is designed, built, and operated by an independent developer in Korea. Advertising covers server costs so that analysis, exercises, and guides stay free. Ads do not influence the content, and we do not recommend specific clinics, procedures, or products.

For questions, bug reports, or content suggestions, email us via the contact page. We usually reply within 2–3 days.
