Face symmetry self-check
Perfect symmetry is rare and not a health goal. Small differences in brows, nostrils, and lip height are normal and often invisible to other people in motion.
Use this check to see whether a difference is something you already knew or something new and one-sided. A new droop, especially with weakness, is a medical issue, not a styling issue.

Want a record of symmetry self-check, not a one-off?
Symmetry self-check on this page is a single reading. The app saves a scan and the routine that followed it, so the next photo has a baseline.
- Six saved scores: hydration, texture, tone, acne, pores, and redness
- A morning and evening routine built from the scan
- The same face, week after week, so a change shows up as a trend

The science
What symmetry self-check measures, and how this page does it
- 01
One question, answered from this photo
Symmetry self-check uses the face in the frame, not a questionnaire. How far paired landmarks sit from the midline: eyes, brows, mouth corners, and jaw. The result is a balance note for this frame, not a beauty score.
- 02
Landmarks first, then the number
The photo is drawn to a canvas in your browser. A face landmark model marks 478 points so the measurement uses the face, not the background. Nothing is uploaded.
The midline is the line from the forehead landmark to the chin. Each pair is compared with its mirror. A tilted phone or a turned chin shifts every pair at once, which is why the note asks you to face the lens.

The result on this page, and the record in the app
How far paired landmarks sit from the midline: eyes, brows, mouth corners, and jaw. The result is a balance note for this frame, not a beauty score.
The AISkincare app keeps a scan: hydration, texture, tone, acne, pores, and redness, then builds a morning and evening routine from those scores. This page answers once and does not store the photo.

What will throw the number off
Sudden one-sided weakness, drooping, or trouble speaking is an emergency. Call local emergency services. This page cannot assess that.
Dental midline, a medical asymmetry, and how a face looks in motion are outside a still photo. Two sides of a living face are not supposed to match exactly.
How to read a symmetry self-check result
The midline is the line from the forehead landmark to the chin. Each pair is compared with its mirror. A tilted phone or a turned chin shifts every pair at once, which is why the note asks you to face the lens.
Use the steps under the tool as the procedure: same light, same distance, same expression, whenever you want a second reading to mean something. The app is where a series of scans can sit next to a routine. This page is the single measurement.
A setup that makes a second photo comparable
Daylight from a window, phone at eye level, an arm's length away, hair off the zones the tool needs, no beauty filter. Tilt in the chin or a camera held low changes several face measurements at once.
If the page warns that the photo looks angled, or that a distance falls outside a usual range, retake before you act on the figure.
One photo is a point. A month is a line.
Symmetry self-check on a Tuesday includes the light in the room. The same check in the same window next month is the comparison that can show a change. Stacking random selfies from different rooms mostly shows the rooms.
Scan the QR code under the tool with the phone you will keep using. An iPhone is sent to the App Store and an Android phone to Google Play, so the history starts in the right store.
What symmetry self-check will not claim
Dental midline, a medical asymmetry, and how a face looks in motion are outside a still photo. Two sides of a living face are not supposed to match exactly.
Sudden one-sided weakness, drooping, or trouble speaking is an emergency. Call local emergency services. This page cannot assess that.
How to use the result
- Use the true mirror page if you want the unflipped view.
- Compare brows, eye height, and the corners of the mouth.
- Ask someone else only if you want a second pair of eyes, not a rating.
Where to go from here
If one part of the result stood out, open the tool that asks only that question. Each one states its limit in the same place, and each one links back to a guide when a longer explanation helps.
- Facial thirds guideSee whether your upper, middle, or lower third is the one that stands out. This is a proportion lesson, not a golden-ratio score.
- Eye shape guidePlace your eyes as almond, round, hooded, monolid, or upturned or downturned so liner and lashes match the lid you have.
- Lip shape guideName your lip shape from the bow, width, and volume so liner and color placement follow the mouth you have.
- Jawline care guideDecide whether your jaw concern is shadow, congestion, or hair removal irritation, then use the matching care. Not a jaw-angle measurement.
