Skin Tracker measures objective numbers from your own skin and shows how they change over time — compared only to your past self. No filters. No diagnosis. No comparison with other people. Just your own measurements, kept consistent so you can actually see what changes. WHAT IT MEASURES • Brightness — how light your skin tone is • Redness — the red tint in your skin • Clarity — dullness vs. a clear, bright tone • Spots — uneven, patchy pigmentation HOW IT WORKS • Your first measurement becomes your personal baseline (50 points). • Every measurement after is shown as the change versus that baseline. • Note when you start a product or treatment ("started retinol") and see the before/after. DOES IT ACTUALLY WORK? Trying a new serum, retinol, or a treatment? You don't need a clinic visit or expensive in‑office equipment to get a read on it. Note when you start, keep measuring under the same conditions, and see whether your own numbers actually move — simply, at home, on your phone. You decide what the change means. BUILT FOR PRIVACY • Camera frames are processed on the fly and discarded immediately — never saved, never uploaded after measurement. • No account, no name, no email. Just an anonymous code that keeps your history. • We never compare you to other people, and we never show ads. FOR BEST RESULTS • Measure in the same place, lighting, and time of day. • Pull your hair back to show your forehead. • Avoid makeup or sunscreen, which throw off the readings. THE METHOD Built by an engineer with a bachelor's in Computer Science and a master's in Artificial Intelligence. Skin Tracker isn't a beauty filter or a guess — it pairs AI face detection with color‑science image processing (skin‑tone ITA°) and noise‑controlled repeat measurement, so the same conditions give consistent, comparable numbers over time. Skin Tracker is a measurement tool, not a medical device. It does not diagnose, treat, or recommend — what the numbers mean and what to do is your call.
