ClearTrace: See what actually affects your skin — a private skin journal

ClearTrace is a private skin journal that connects your daily habits — sleep, stress, water, food — to how your skin looks the next day. Take one guided AM & PM photo, log your day in under a minute, and watch a private skin score reveal the patterns behind your breakouts and glow-ups. Then export a clean, dermatologist-ready PDF. It's a wellness tracker — not a medical device. Your photos and logs stay yours.

Hey Product Hunt 👋 I'm Onurcan, the maker. I built ClearTrace because I was tired of guessing what was breaking me out. New serum? Stress? That week of bad sleep? I had no idea. So I made an app that turns a daily photo + a one-minute habit log into actual correlations — "higher stress → more redness the next day," with a confidence score — instead of vibes. A few principles I care about: it's a wellness tracker, not a medical device (no diagnoses, just observations), it's private by design (export or delete everything anytime), and the guided photo uses a face overlay + a ghost of yesterday's shot so every picture lines up. Would love your feedback — especially on the correlation insights and what factors you'd want to track. Happy to answer anything!

Took my morning photo and logged a rough night of sleep plus a coffee binge, and the score shift the next day was eerily accurate. The PDF export is a nice touch if I ever actually go see a derm.
