HomeSkin WorryCheck your skin onlineOnline Skin Screening — What It Is and When to Use It
Quick answer
Online skin screening is an AI-powered check of a photo you take of a mole, spot or rash. ScanSkinAI runs in your phone browser, returns a likely category and confidence score in around 30 seconds, and tells you whether the lesion looks suspicious enough to warrant professional review.
Key takeaways
- Online skin screening is triage — not diagnosis.
- It is most useful for visible lesions you can clearly photograph.
- It can save unnecessary GP visits for clearly benign findings.
- It can also speed up referral when something looks suspicious.
- Use it monthly for moles you're tracking, or once-off for a new concern.
If you've ever waited two weeks for a GP appointment to be told a spot is harmless, online skin screening is the step in between. It doesn't replace the doctor — it tells you whether the doctor visit is the right next step.
When online screening is a good fit
Online AI screening is best when the lesion is visible, can be cleanly photographed, and isn't currently bleeding, infected or extremely painful. Those need real care, not a screening tool.
- A new mole you've just noticed
- A long-standing mole you want to monitor
- A rash that comes and goes
- A spot that looks different from the rest
- A change you've noticed in a known mole
When to skip the screening and go straight to a doctor
If a lesion is bleeding, has been there over 4 weeks without healing, is rapidly changing, or is associated with fever, fatigue or unexplained weight loss — book a doctor first. Use the screening as a record to bring with you, not as a gate.

Who is this useful for?
When should you seek professional advice?
See a doctor or dermatologist promptly if you notice:
- A non-healing sore over 4 weeks
- A pigmented lesion changing rapidly
- A new lump that is firm, growing or attached underneath
- Generalised rash with fever, breathing difficulty or facial swelling
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
Is online screening the same as a diagnosis?
No. Screening narrows down what something might be and recommends next steps. A diagnosis requires a clinician and often dermoscopy or a biopsy.
Can I use this instead of a dermatologist?
No. It can help you decide whether you need a dermatologist, and it can speed up the conversation, but it does not replace one.
Will my GP take it seriously?
Most clinicians find a clear photo and a documented change history useful. ScanSkinAI lets you export a report you can show or send.
Is it covered by insurance?
ScanSkinAI is free to try. Some employer and insurer programmes cover the paid tracking and dermatologist review tier — check our partners list.
What if the AI gets it wrong?
AI can produce false positives and false negatives. The recommendation is always to seek a doctor for anything that worries you, regardless of the AI score.
