Quick answer
A sore that won't heal on the nose is most often Basal cell carcinoma, Squamous cell carcinoma, Venous leg ulcer. A break in the skin that hasn't closed within 4–6 weeks despite normal care. 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 sore that won't heal 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 sore that won't heal here.
Most likely causes
Basal cell carcinoma
Classic "non-healing sore" — often on the face or scalp.
Squamous cell carcinoma
Scaly, sometimes ulcerated lesion on sun-damaged skin.
Venous leg ulcer
Shallow ulcer above the inner ankle in older adults.
Diabetic foot ulcer
Painless ulcer on pressure points in diabetes.
