Facial thirds, in plain language
Artists split the face into three bands: hairline to brow, brow to the base of the nose, and base of the nose to the chin. Classical drawings make them equal. Real faces are not drawings.
Knowing which band is longer explains why a fringe, a beard, or a brighter lip changes the balance. It does not produce a score out of ten.

Want a record of facial thirds guide, not a one-off?
Facial thirds guide 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 facial thirds guide measures, and how this page does it
- 01
One question, answered from this photo
Facial thirds guide uses the face in the frame, not a questionnaire. The three horizontal bands of the face: hairline to brow, brow to nose base, and nose base to chin. The page says which band takes the most space in this photo.
- 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.
Forehead, brow, nose, and chin landmarks divide the length into three. Hair covering the forehead landmark shortens the top third. A low camera lengthens the bottom third.

The result on this page, and the record in the app
The three horizontal bands of the face: hairline to brow, brow to nose base, and nose base to chin. The page says which band takes the most space in this photo.
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
This is a cosmetic self-check for education. It is not a diagnosis, a treatment plan, or a measurement from a clinical device.
Equal thirds are a drawing convention, not a health target. The page does not tell you to change a third.
How to read a facial thirds guide result
Forehead, brow, nose, and chin landmarks divide the length into three. Hair covering the forehead landmark shortens the top third. A low camera lengthens the bottom third.
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.
Facial thirds guide 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.

How to use the result
- Look straight ahead in a mirror, not from above.
- Cover each third with a hand and see which one your eye hits first.
- Hairline recession changes the upper third. That is common.
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.
- 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.
- Profile balance guideLearn what a side photo can suggest about brow, lips, and chin balance, and what it cannot measure. No attractiveness score.
