Sebaceous Hyperplasia

What is Sebaceous Hyperplasia?

Sebaceous hyperplasia is a benign skin condition where the sebaceous (oil) glands become enlarged, leading to small, soft bumps on the skin. These bumps are usually flesh-coloured or yellowish, with a central dip, and often appear on the forehead, cheeks, and nose. They are harmless but can be mistaken for other skin conditions.

Causes

The exact cause is not fully understood, but contributing factors include:

Overactive sebaceous glands producing excess oil.

Ageing – more common in middle-aged and older adults.

Genetics – family tendency to develop the condition.

Hormonal changes – may stimulate gland growth.

Sun damage – long-term UV exposure may increase risk.

Immunosuppressive medications (e.g., cyclosporine) can trigger it.

Symptoms / Appearance

Small soft bumps (2–4 mm) on the skin.

Flesh-coloured, yellow, or pink in appearance.

A central dip (indentation or “umbilication”).

Most commonly appear on the face (forehead, nose, cheeks).

Usually painless, but may be mistaken for basal cell carcinoma (skin cancer).

Treatments

Since sebaceous hyperplasia is harmless, treatment is usually cosmetic.

Professional Treatments

Laser therapy (CO₂ or pulsed dye laser) – removes bumps with precision.

Electrocautery / diathermy – burns away lesions.

Cryotherapy – freezes lesions with liquid nitrogen.

Chemical peels – help reduce oiliness and improve texture.

Photodynamic therapy (PDT) – targets sebaceous glands.

Prescription creams – retinoids (tretinoin) can help reduce bumps.

FAQs

Q1. Is sebaceous hyperplasia dangerous?
No – it is benign and not cancerous, though it can look similar to basal cell carcinoma.

Q2. Can sebaceous hyperplasia go away on its own?
It usually does not disappear without treatment but may remain stable.

Q3. How can I tell the difference between sebaceous hyperplasia and skin cancer?
Sebaceous hyperplasia has a central dip and is usually soft and uniform. Skin cancer may be irregular, growing, bleeding, or painful. Always get suspicious spots checked by a dermatologist.

Q4. Can I squeeze or pop sebaceous hyperplasia bumps?
No – squeezing won’t remove them and may cause irritation or scarring.

Q5. Who is most at risk?
Middle-aged to older adults, people with oily skin, and those with excess sun exposure.
