Not sure what's on your skin? Upload a clear photo and use ScanSkinAI's AI skin checker to analyse visible features of a skin concern.
The tool compares image patterns with supported skin-condition categories and provides possible matches and next-step guidance in seconds.
It is designed for preliminary screening and education, not confirmed medical diagnosis.

- Upload a photo — no app required
- 80 supported skin-condition categories
- Results in seconds
- Validated across Fitzpatrick skin types I–VI
- Screening aid — not a diagnosis
Most users scan once and feel reassured. The ones who catch problems early scan every 4–6 weeks and compare results over time.
What Is This on My Skin?
Many skin concerns look similar in photographs. Visible features such as colour, texture, border, scaling, shape and location can give useful clues about what a spot, patch or bump might be — but a photo alone does not capture the full clinical context, including symptoms, medical history, how the area has changed over time, or anything that needs to be felt or tested.
The AI skin checker analyses those visible image features and returns possible condition matches alongside next-step guidance, so you have somewhere sensible to start rather than guessing from search results. It does not confirm a medical diagnosis, and it is not a substitute for an assessment by a qualified healthcare professional.

AI analyses visible features
The system evaluates image characteristics such as colour, texture, border and pattern, and compares them with supported skin-condition patterns.
Review possible matches
The result presents preliminary possibilities and screening information rather than a confirmed answer.
Review suggested next steps
Depending on the result and your symptoms, you may be advised to monitor the area or seek appropriate professional care.
Results are preliminary screening information and guidance — never a confirmed diagnosis.

Can You Get a Skin Diagnosis From a Photo?
People often search for a "skin diagnosis by photo", but image-based AI tools should be understood as screening aids rather than a substitute for clinical diagnosis. ScanSkinAI analyses visible image patterns and can suggest possible matches and next steps, while a qualified healthcare professional may need history, examination, tests or a biopsy to confirm a diagnosis.
What AI Skin Analysis Cannot Do
It does not provide a confirmed diagnosis
The output is preliminary screening information, not a medical diagnosis.
It cannot replace clinical examination
Some conditions require physical examination, medical history, laboratory testing or biopsy.
Image quality matters
Poor lighting, blur, distance or obstruction can affect image analysis.
It cannot identify every skin condition
Some concerns fall outside supported categories or cannot be assessed reliably from a photo.

AI screening can help you understand possible next steps, but some symptoms need medical attention regardless of what any tool says. Seek care promptly if you have:
Also seek assessment for anything that is severe, rapidly worsening or persistent. A reassuring AI result does not rule out a condition and should not delay appropriate medical evaluation.
Evidence and Validation
In an independent 100-case dermatologist audit, ScanSkinAI achieved 95.3% clinically acceptable accuracy across 80 skin conditions and Fitzpatrick skin types I–VI. Clinically acceptable accuracy is a screening measure used in medical AI validation literature: it describes whether the response was a safe and reasonable first-pass screening result, not whether a diagnosis was confirmed.
Performance varies by condition, image quality and the characteristics represented in the training and validation data. Intended use, limitations, medical review and regulatory information are documented in full alongside the audit methodology.
Your Photos and Your Privacy
Images you upload are transmitted over an encrypted connection and processed to generate your screening result. If you have an account, your scans can be saved to your history so you can compare an area over time. How images and results are retained, used and deleted — and the choices available to you — is set out in our Privacy Policy.

Yes. You can upload a photo from your phone or computer, or take one directly in your browser. No app download is required.
Yes, you can start a skin check for free. Optional paid extras, such as a dermatologist review, are available separately.
AI can identify visual patterns associated with supported skin-condition categories and suggest possible matches. It cannot confirm what a condition is, because a photo does not capture medical history, symptoms or test results.
No. People often search for a skin diagnosis by photo, but image-based AI should be understood as a screening aid. A confirmed diagnosis requires a qualified healthcare professional and may need history, examination, tests or a biopsy.
ScanSkinAI screens for patterns associated with 80 visible skin conditions, grouped into inflammatory concerns, infections, pigmented lesions, common skin growths, acne-related concerns and suspicious skin changes.
In an independent 100-case dermatologist audit, ScanSkinAI achieved 95.3% clinically acceptable accuracy across 80 skin conditions and Fitzpatrick skin types I to VI. That is a screening measure, not diagnostic accuracy, and performance varies by condition, image quality and the characteristics represented in the validation data.
Retake the photo with better lighting and focus, and include some surrounding skin. If the result stays unclear, or the concern persists or worsens, arrange an in-person assessment with a healthcare professional.
Seek professional care for concerns that are painful, spreading, bleeding, rapidly changing, persistent, or accompanied by fever or feeling unwell. A reassuring AI result should never delay care for a symptom that worries you.
Images are transmitted over an encrypted connection and processed for your analysis. How images are retained, used and shared is described in our Privacy Policy, which we recommend reading before uploading.
