One product. Twenty-eight days.

Trace now reads your latest photo and picks a single product for you, then asks you to stay with it for 28 days. One thing at a time is the only way to tell what actually made a difference. Your daily photos do the rest.

Your skin diary, out loud
Hold the button and just talk about your day. Buddy turns it into notes on that day's page, so food, sleep, stress and new products sit right next to what your skin is doing.

Trace now speaks your language
The whole app is available in French, German, Spanish and Simplified Chinese. Switch any time in Settings.

Your photos follow you
Reinstall the app or move to a new phone and your history comes back, every day and every layer.

Also in this release
A crash when sending a voice note is fixed, along with a long list of smaller rough edges across the diary, the timeline and your report.
