Set it. Stick to it. See it.

A method borrowed from clinical trials: a fixed baseline, a routine you keep, checkpoints you compare.

  1. 01 · Set

    Day 0 is your baseline: four photos of fixed zones, framed the same way every time after.

  2. 02 · Stick

    Follow your routine day by day. Quiet reminders, no streaks to break.

  3. 03 · See

    Every 30 days, reshoot the same zones and compare two dates side by side.

Lock in your Day 0
