Sebaceous Hyperplasia - Symptoms, Causes & Treatment
Medically reviewed by Dr. Anand S. Urhekar, MD, MD Pathology, Clinical Advisor · Last updated July 2026
Harmless enlargement of oil glands producing small, soft, yellowish bumps 2–5 mm across with a central dimple, typically on the forehead, nose and cheeks of adults over 40. The doughnut shape and yellow colour distinguish it from basal cell carcinoma, though the two can look similar.

Quick Answer
Sebaceous hyperplasia is an enlarged oil gland, appearing as a soft yellow or cream bump 2–5 mm wide with a central dip, most often on the forehead and nose after age 40. It is completely benign. Treatment is cosmetic only — electrocautery, laser, cryotherapy or topical retinoids. Because it can mimic basal cell carcinoma, a new or bleeding lesion should be checked in person.
Symptoms
- Soft yellow or cream-coloured papules 2–5 mm across
- Central dimple or umbilication
- Doughnut-shaped rim, sometimes with fine surface vessels
- Forehead, nose, cheeks; occasionally chest
- Painless, stable in size for years
Causes & Risk Factors
- Age-related enlargement of sebaceous glands
- Reduced androgen activity with age
- Long-term ciclosporin use after transplant
- Genetic predisposition and oily skin
Treatment & Management
- No treatment necessary
- Electrocautery or hyfrecation
- Laser treatment (CO2 or pulsed dye)
- Cryotherapy or light chemical peel
- Topical or oral retinoids for widespread lesions
When to See a Doctor
See a doctor if a bump grows, bleeds, ulcerates or develops a pearly rolled border, as basal cell carcinoma can look very similar.
Frequently Asked Questions
How do I tell sebaceous hyperplasia from basal cell carcinoma?
Sebaceous hyperplasia is yellow, soft and stable, with a central pore. Basal cell carcinoma is pearly, may bleed or crust, and slowly grows. If it is changing or bleeding, get it examined — dermoscopy makes the distinction quickly.
Can I squeeze it out?
No. It is an enlarged gland rather than a blocked pore, so squeezing produces nothing and risks scarring and infection.
