Popular questions about identifying skin symptoms
How do I use skin symptom pictures to identify a rash?
Compare the shape, colour, distribution and texture of your rash against the reference photos on each symptom page. Look for matching size (pinpoint vs patch), border (sharp vs fuzzy), colour (red, purple, white) and body location. If you're still unsure, upload your own photo to the free AI skin checker for a side-by-side comparison against thousands of dermatology images.
Can I identify a skin condition from a photo?
Photos suggest likely causes but do not confirm a diagnosis. ScanSkinAI's free AI checker analyses a photo in seconds and returns the most likely conditions with a confidence score. Always confirm concerning findings with a qualified clinician.
Are the photos on these pages real clinical images?
Yes. All hero photos are real clinical or user-supplied images (Wikimedia Commons public-domain sources, user submissions, or clinical references) with visible credit and no identifying facial features.
Which skin symptoms need same-day medical care?
Any non-blanching purple rash with fever, facial or lip swelling, trouble breathing, one red warm painful spreading area on a limb, blistering skin, or any rash in a child with fever — go to A&E or call emergency services.
Is the AI skin checker free?
Yes — the AI skin and rash checker on ScanSkinAI is free, requires no app download or account, and returns likely causes in seconds. It is a screening aid, not a medical diagnosis.
