Editorial process

A face tool makes claims about people, so the bar for what we publish is high. This page explains how a measurement, statistic or tip gets onto FaceCheckup, and what keeps it there.

1. Start from a real question

Every page answers a question people actually ask, such as “is my forehead big?”, “what is canthal tilt?” or “which haircut suits a heart-shaped face?”. We collect these questions from search data, public Q&A sites, forums and video comments before deciding what to write. Before writing, we read the pages that already rank for the question, and we only publish if we can add something they lack: a working measurement on your own photo, a cited figure, or a clearer method.

2. Name the source for every claim

Before a page is drafted, we list every figure, range and fact it will state, and where each one comes from. Sources rank in this order:

• Peer-reviewed research and anthropometric references: studies that measured real faces, with sample sizes and methods stated.
• Official documentation, for example Google's documentation for the MediaPipe face model the scan uses.
• Professional guidance from named stylists, opticians, makeup artists and the organisations and brands that train them. These are labelled as conventions, not science.
• Established publications with a named author, used for context.

A figure we can’t trace to a source is left out. Hedges such as “experts say” or “studies show” without a named study are not used. Each page lists its sources at the bottom, and figures are cited where they appear.

3. Say what the evidence does not support

Popular ideas about faces often go further than the research. Examples are “the golden ratio defines beauty”, “mewing changes your bone structure”, and the idea that one number can say how attractive someone is. When a page touches one of these, it says plainly what the evidence shows and what it doesn’t. We never publish surgery, filler, bone-smashing, mewing or supplement advice.

4. Test the tool on real photos

Measurement code changes are tested on real photos: straight-on, turned, tilted, smiling, close-up and badly lit. We check that the photo-quality check catches the bad ones, and that the ± range reflects how much a measurement really moves between re-framings of the same photo. Known limits are written up on How it works, not hidden.

5. Independent checking

Each page is checked by a second reviewer who did not write it. They test whether the page answers the question better than what already ranks, and they check its figures against the cited sources. Pages that fail are rewritten, merged into another page, or dropped.

6. AI assistance

Articles on this site are researched with AI assistance and edited by Sukie before publication. Every measurement and figure is checked against the published sources listed on each page. AI tools help with research and first drafts. They are never used to invent figures, quotes, sources or user stories, and every page is edited before it goes live.

7. Updates and corrections

Pages are reviewed at least once a year, and sooner when a source changes. The “updated” date on a page changes only when its content does. If you find an error, email sukielovesupport@gmail.com. Confirmed errors are corrected promptly, and substantive corrections are noted on the page.

8. Money and independence

FaceCheckup is funded by advertising and by the optional one-time Full Face Report. Advertisers have no say in content, ads are never placed over the scan, and nothing on the site is sponsored. We don’t take payment for product mentions, and we don’t recommend cosmetic procedures.
