HomeSkin WorrySpot identificationWeird Bump on Face — What Is It?
Quick answer
Most facial bumps are milia, sebaceous cysts, fibrous papules, or simply persistent acne. A small number can be basal cell carcinomas — slow-growing pearly bumps that don't go away. Run a free AI screening to identify the bump in around 30 seconds.
Key takeaways
- Most facial bumps are benign milia, cysts or papules.
- Pearly, non-healing bumps deserve review for basal cell carcinoma.
- Acne lesions usually resolve in 1-3 weeks; persistent bumps don't.
- AI screening narrows the bump to a likely category in 30 seconds.
- First scan is free — no app required.
Faces collect bumps. Sebaceous glands clog, hair follicles inflame, tiny keratin pearls form under the skin. Most are completely benign and many will resolve on their own.
Common harmless bumps
Most new facial bumps are one of these completely benign growths.
- Milia — tiny white keratin pearls (often under eyes)
- Sebaceous cyst — soft, dome-shaped lump with central pore
- Fibrous papule — small firm bump on the nose
- Sebaceous hyperplasia — yellow donut-shaped bump
- Persistent cystic acne
When a facial bump deserves review
A pearly, slow-growing bump with tiny visible blood vessels — especially on the nose, ears or temples — is the classic look of basal cell carcinoma. It's slow but it doesn't go away.
- Pearly bump with visible blood vessels
- Slow growth over months
- A scab that keeps re-forming
- Spontaneous bleeding when washing
- Any bump present 6+ weeks without resolving

Who is this useful for?
When should you seek professional advice?
See a doctor or dermatologist promptly if you notice:
- A pearly facial bump growing slowly over months
- A bump that bleeds or scabs repeatedly
- A bump present 6+ weeks without resolving
- Any new growth on a sun-exposed face area
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
What are the tiny white bumps under my eyes?
Most are milia — tiny keratin cysts. They're harmless and a dermatologist or aesthetician can remove them cosmetically.
Why won't this 'pimple' heal?
Acne lesions usually resolve in 1-3 weeks. A 'pimple' that lasts 6+ weeks isn't acne — it's worth screening.
Are sebaceous cysts dangerous?
No — they're benign. They can be drained or excised by a doctor if they become inflamed or cosmetically bothersome.
Where on the face does basal cell carcinoma appear?
Most often on the nose, ears, temples, and lips — areas with the most cumulative sun exposure.
Can I scan a facial bump with AI?
Yes. Take a clear, well-lit photo with the bump centred, and ScanSkinAI will return a likely match in around 30 seconds.
When should I see a GP?
Any non-healing or slow-growing bump on the face deserves a GP review — especially if AI flags it.
