HomeSkin WorrySpot identificationWhat Is This Spot on My Skin? Identify It in 30 Seconds
Quick answer
Most skin spots are benign — common moles, seborrhoeic keratoses, cherry angiomas, dermatofibromas or post-inflammatory marks. ScanSkinAI compares your photo against 200+ skin conditions in around 30 seconds and tells you whether to monitor or see a doctor. It's free for the first scan.
Key takeaways
- Most spots are benign and stable — moles, keratoses, angiomas, scars.
- AI screening narrows it down to a likely category in around 30 seconds.
- Anything new, growing or changing deserves closer review.
- ABCDE warning signs apply to pigmented spots.
- Free first scan — no app, no credit card required.
Skin marks come in only a handful of common shapes: flat brown spots, raised pink bumps, rough scaly patches, red dots, or non-healing sores. Knowing the category is half the answer — and an AI screening can do that in seconds.
The most common harmless spots
Most adult skin spots fall into one of these benign categories.
- Common mole (nevus) — round, even-coloured, stable
- Seborrhoeic keratosis — waxy, 'stuck-on' brown patch
- Cherry angioma — bright red dot, harmless
- Dermatofibroma — firm brown bump on the leg
- Skin tag — soft, dangling flap, usually in folds
When a spot deserves a closer look
Use the ABCDE rule for pigmented spots and the 'won't heal in 4-6 weeks' rule for sores. Either pattern is enough to justify an AI screening today.
- Asymmetric shape or border
- Multiple colours or recent darkening
- Larger than 6 mm
- Visibly changing in weeks
- A sore that won't heal in 4-6 weeks

Who is this useful for?
When should you seek professional advice?

- A spot that's changing month on month
- A sore that won't heal in 4-6 weeks

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
How does an AI tell me what a spot is?
ScanSkinAI compares your photo against a library of 200+ skin conditions and returns the most likely matches with a confidence score and a recommendation.
Is the first scan really free?
Yes — your first AI screening is free, with no credit card required.
Can AI replace a dermatologist?
No. AI screening is a triage tool to help you decide whether to monitor or see a clinician. A dermatologist always has the final word on diagnosis.
How accurate is ScanSkinAI?
Our internal validation shows around 95% concordance with dermatologist labels across common conditions and skin tones.
Do I need to install an app?
No. ScanSkinAI runs in your phone browser. No download, no account required for the first scan.
What if my spot is in an awkward place to photograph?
Ask someone to help, or use a mirror. The lesion should fill the centre of the frame with even, natural light.
