Quick answer
A skin scan from your phone works by photographing the area of concern through ScanSkinAI in your browser. The AI analyses the image in around 30 seconds and returns a likely category, a confidence score, and a recommendation on whether to monitor or seek professional review.
Key takeaways
- Any iPhone or Android phone with a working camera will work.
- Good lighting and a clean lens make the biggest difference to accuracy.
- Result returned in around 30 seconds.
- Free first scan — no app download or account required.
- Use it as a triage tool, not a diagnosis.
If you've ever held your phone up to a mole or spot and wondered what it actually was, you're not alone. Phone-based skin scanning is one of the fastest-growing ways people get reassurance about a skin concern — and ScanSkinAI is designed to give you a usable answer in under a minute.
How to get the best phone skin scan
Image quality drives accuracy. Two minutes spent on framing and lighting is worth far more than upgrading your phone.
- Wipe your camera lens with a clean cloth or soft sleeve.
- Stand near a window for indirect daylight, or use a soft lamp.
- Avoid the camera flash — it washes out colour and texture.
- Hold the phone 10–15 cm from the skin and tap to focus on the lesion.
- Frame the area in the centre, filling about 60% of the photo.
What ScanSkinAI does with your photo
The image is sent to our AI model, which has been trained on a large library of dermatologist-labelled skin images. It returns a likely category, a confidence score and a recommendation.
Your scan can be saved to a free account so you can re-photograph the same spot weeks later and compare side-by-side.

Who is this useful for?
When should you seek professional advice?
See a doctor or dermatologist promptly if you notice:
- A spot that bleeds, oozes, or won't heal in 4 weeks
- A mole that itches, hurts, or is growing fast
- Sudden onset of widespread rash with fever or breathlessness
- Any lesion that worries you, even if the AI says it looks benign
What AI skin analysis cannot do
- It cannot diagnose skin cancer, melanoma or any disease.
- It cannot replace a dermatologist, GP or other clinician.
- It cannot replace dermoscopy, biopsy or clinical examination.
- It cannot prescribe medication.
- Image quality (focus, lighting, framing) materially affects results.
- For worrying or rapidly changing symptoms, always seek medical advice.
Frequently asked questions
Do I need a special camera?
No. The standard camera on any phone made in roughly the last six years is enough. A dermatoscope is not required.
Does the scan work in low light?
Image quality drops in low light. Find a window or a lamp before scanning. The app will warn you if the photo is too dark or blurry.
How long does the scan take?
Around 30 seconds from upload to result, depending on your internet speed.
Can I scan moles on my back?
Yes — ask a partner or use the rear camera with a mirror. Keep the lens clean and the lesion in focus.
How private is this?
Photos are encrypted in transit and stored securely if linked to your account. Guest scans are used only for the immediate scan. See our privacy policy for full detail.
