FAQ

No. MIRRA measures and tracks — it does not diagnose medical conditions and does not replace a doctor. For any unusual or stubborn finding, our recommendation will always be a dermatologist.

The integrity of the numbers. Most apps return a score designed to flatter. Here every metric is calibrated against measurement noise, every threshold cites a research source, and when there’s no measurable change — that’s the answer you’ll get. Our mirror doesn’t flatter; it’s precise.

The app is free — tracking, experiments, the shelf and the advisor are open to everyone. A subscription buys the face scans only: the first 7 days free, then monthly, quarterly or yearly (local price shown in the app), up to 3 scans a day.

Yes, for as long as your account exists: from every scan we keep a copy of the photo (at most 1440 pixels) and a crop of your face. While you scan, the photos are also sent to Google Gemini, without your name. The app requires signing in with Google or Apple, and deleting the account in Settings deletes the photos from our server right away.

Any iPhone or Android from recent years with a decent front camera. No external device needed.

Very soon. Search for MIRRA in the stores — or come back here; the buttons above will update on launch day.

Once a day is the rhythm the product is built on — at the same window and the same hour when you can. Every scan is compared to yesterday’s, and the fewer things changed between them, the more the difference means. Up to 3 a day; more than one only if the first was refused.

Starting a new product opens a test: daily scans, the metrics the product should move, and after thirty days one of three verdicts — it worked, it did not, or “no measurable change”. The last one is a real answer: the product changed nothing your face can show, and that saves you buying it again.

Because the image would have given a guess with a number beside it. Blur, a tilted head, a smile, make-up, hair on the forehead or too little light — each moves the reading more than skin does, so the scan asks again instead of measuring. In practice about 45% of frames are refused; a window, an arm’s length and a still moment pass.

Your scans, your shelf and your journal — nothing else. She answers from your own numbers: which metric is weakest, which ingredient on your shelf addresses it, and what conflicts with what. She does not diagnose, and for anything unusual she will send you to a dermatologist.

It explains, it never scores. With your permission the app reads UV, temperature and humidity where you are; they never enter a score, but they explain why a reading moved — a dry week, a UV spike — and they change a recommendation, like a retinoid on a high-UV day.

Yes. Beside the products, each weak metric lists the home devices and clinic treatments the ingredient knowledge base connects to it — an LED mask, radiofrequency, a peel, IPL — with one honest line each: what it does and how long it lasts. Anything injectable is marked physician only.
