How it works

Boirelle asks three things and answers with one routine — then shows its working.

Take a selfie

Front camera, natural light, no filter. There is no questionnaire, no quiz and no account. Before the photo leaves your device it is scaled down to 1024 pixels on its longest edge — the version that gets analysed is small by design.

Read your skin

Hydration, oil, texture and redness as they are today — these change week to week. Then undertone, face shape and eye colour, which do not. Underneath, one plain sentence about what the reading means for your makeup.

Say where you are going

Everyday, work, dinner, a wedding, photographs or a night out. A wedding is not a Tuesday, and the routine knows the difference — the same skin gets a different face depending on where it is going.

And how long you have

Five, fifteen or forty-five minutes. The routine is built to fit that time, not trimmed to fit it — five minutes gets three or four steps that matter, not a long routine with the end cut off.

Follow the routine

Numbered steps in order, each with the product category, one line on how to apply it and how long it takes. Every step names a specific product, so nothing is left as a guess at the counter.

Try the shades on first

Lip, cheek and eye, painted onto your own scan rather than a model. The shades your undertone actually suits are marked, the strength is yours to set, and one tap takes it all off. Part of Unlimited.

See what changed

Scan again in a few weeks and the two photographs sit under one slider, with the readings that moved listed underneath — old to new, in plain words. Part of Unlimited.

The Boirelle compare screen: two scans of the same face split by a vertical slider, dated old and new, above a list of readings that changed. — Then and now

Check where it comes from

Every reading and every step is traced back to published dermatology guidance — the American Academy of Dermatology and the NHS among them. Each line opens the source itself.

What it is not

Boirelle gives cosmetic guidance. It does not diagnose skin conditions, name diseases or recommend treatments. If something about your skin concerns you, show it to a doctor or a dermatologist.
