Proof Skincare: Face Scanner

Stop guessing. Start knowing. Proof measures your skin daily and runs real experiments on your routine - so you know which products actually work.

Your skin. Measured, not guessed.

Every skincare opinion you've ever heard - from influencers, from forums, from the mirror on a good day - is a guess. Proof replaces guessing with measurement.

HOW IT WORKS

• Take a short guided scan. Same distance, same light, same angle - Proof's capture guide makes every scan comparable, and tells you when conditions differ from your usual ones.
• Proof measures what a camera can honestly measure: redness, breakouts, skin calmness, texture, even tone and shine.
• After ten scans you have something almost nobody has: a real baseline of what's normal for YOUR skin, including how far it moves on its own from one day to the next.

THEN RUN EXPERIMENTS

Change one thing - add a serum, drop a cleanser. Measuring starts the day you begin, and you choose how long it runs. Proof then gives you a verdict grounded in statistics: did anything actually change, and how sure can it be?

Because an experiment checks all six measurements at once, and checking more things is more chances to see something that isn't there, the threshold for calling any of them a change is raised accordingly. Whatever genuinely moved is listed first.

After each scan during an experiment, Proof asks in one tap whether you used the product, and what your skin felt like. A product you used on three days out of seven can't be judged fairly - and Proof says so, instead of reporting "no change" with confidence it hasn't earned.

WHAT MAKES PROOF DIFFERENT

• Honest numbers. Every metric is genuinely measured from your scans. Proof never invents a reading it can't back, and says "no real change" plainly when that is the answer.
• Your own scale. Proof shows how much your score moves on its own, so you can tell a result from ordinary variation.
• Private by design. Your face photos never leave your iPhone. All analysis happens on-device.
• No shame, no hype. Your skin isn't graded against anyone else's - only against your own baseline.
• It shows its working. A plain-language page explains exactly what one scan measures, why the first ten scans come first, and what Proof refuses to claim.

YOUR SHELF, DECODED

Scan a product's barcode to add it. Proof reads ingredient lists, flags combinations that commonly irritate when layered, spots actives you are already covered for, and reminds you when an opened product is past its best.

A monthly report shows what moved and what held steady, and you can export everything you have measured at any time. Both are included for free.
