Apps that scan moles and acne use AI — here's how to use them safely.
7 min · Reviewed 2026
The big idea
There are apps that take a photo of a mole or rash and tell you if it looks risky. They're trained on thousands of images and can be helpful — but they also miss things and freak people out for no reason.
Some examples
Useful for: tracking how a mole changes over months.
NOT useful for: deciding if it's cancer with zero doctor visit.
Helpful for: deciding if acne treatment is working.
Risky for: anything bleeding, growing fast, or new and weird.
Try it!
If you use a skin app, screenshot a baseline photo today and recheck in 30 days. Real change? Show a real doctor.
