Nose Bumps (Sebaceous Hyperplasia): Causes, Treatments & When to Treat

Small, yellowish-white bumps on the nose are often sebaceous hyperplasia—enlarged sebaceous (oil) glands. Common on the face (nose, cheeks, forehead) in adults >40, especially with oily skin.

Causes & Risk Factors

• Age-related hormonal changes (androgen sensitivity)
• Genetics
• Sun exposure (UV damage)
• Immunosuppression (e.g., post-transplant)

Clinical Features

• 1–3 mm, soft, umbilicated (central dell) papules
• Yellowish-white, translucent
• Asymptomatic, cosmetic concern only
• Not malignant, but can mimic basal cell carcinoma

Treatment Options (Cosmetic)

• Electrodesiccation / Laser (CO₂, Erbium:YAG): Precise ablation; low scarring risk.
• Chemical peels (TCA): Superficial; may require multiple sessions.
• Topical retinoids (tretinoin, adapalene): Reduce gland size over months; preventive.
• Photodynamic therapy (PDT): For extensive lesions.

When to See a Dermatologist

• Diagnosis uncertain (rule out BCC, molluscum, milia)
• Lesions grow, bleed, ulcerate, or change color
• Desire treatment for cosmesis

Sebaceous hyperplasia is benign. Treatment is elective; recurrence is common without maintenance (retinoids).
