Quick answer
A scab on the nose is most often Impetigo, Eczema with scratching, Basal cell carcinoma. A crust of dried blood and fluid covering a small wound or sore. Because the nose has heavy lifetime sun exposure, certain patterns are more likely here. Use the ABCDE-style red flags below to decide whether to monitor at home or book a dermatology review — most are harmless, but a few need quick attention.
Why a scab on the nose is different
The nose is the single most sun-exposed point on the face and one of the commonest sites for basal cell carcinoma — a mole, scab or sore on the nose that will not heal deserves prompt review.
The most common day-to-day triggers in this area are daily UV exposure, glasses friction, frequent touching — each of which can produce or worsen a scab here.
Most likely causes
Impetigo
Honey-coloured crusts — bacterial, contagious.
Eczema with scratching
Scabs from breaking the skin in itchy areas.
Basal cell carcinoma
Skin cancer that repeatedly scabs and re-bleeds.
Healing cold sore
Crust phase of a herpes blister.
Red flags — see a clinician
- •Scab keeps re-forming in the same place for >4 weeks
- •Honey-coloured crusts spreading on the face (impetigo)
- •Surrounding spreading redness or fever

In the UK, start with your GP, who can examine the area and refer you to NHS dermatology (urgent suspected-cancer referrals are seen within two weeks). You can also book a private dermatology consultation directly. Elsewhere, see your primary care doctor or a dermatologist.
Self-care while you decide
- ✓Do not pick — it delays healing and risks scarring
- ✓Keep moist with a thin layer of petroleum jelly
- ✓Cover if exposed to friction
