Build a baseline
Mark each mole on the body map, name it, and capture a first image so future changes have a reference point.
Track evolution
Repeat photos under similar lighting and distance to compare changes in risk score, color, border, asymmetry, and visible structures.
Know when to escalate
Rapid change, bleeding, pain, irregular border, multiple colors, or a lesion that looks different from the rest should prompt medical review.
Keep data private
Private photos require login and are served with short-lived signed URLs instead of public image links.
