When is CO2 laser resurfacing recommended for sebaceous hyperplasia?

Sebaceous hyperplasia consists of enlarged oil glands that appear as small, usually skin-coloured or yellowish bumps, often on the face. CO2 energy can vaporise selected lesions and smooth the surface. It is generally considered when the diagnosis is clear and the bumps are cosmetically troublesome, repeatedly irritated, or difficult to manage with simpler options. It should not be used to assume that every facial bump is sebaceous hyperplasia; a firm, dark, ulcerated, bleeding, or changing lesion needs assessment.

Treatment can leave temporary redness, crusting, or a colour change, particularly in skin that darkens after inflammation. Bumps may also recur because the tendency of oil glands to enlarge is not necessarily removed.

Ask a dermatologist to confirm the bumps and compare CO2 treatment with alternatives suited to your skin and lesion pattern. Mention previous pigmentation after cuts or burns, cold sores, medicines, active dermatitis, and any history of raised scars. Discuss whether a test area is sensible, how many lesions may be treated in one visit, and the expected surface healing. Keep the treated skin clean, do not squeeze crusts, and use the recommended sun protection while colour settles.

Contact the clinic for increasing pain, warmth, swelling, pus, spreading redness, fever, or bleeding that does not settle. Request an examination for any bump that changes quickly, becomes sore, bleeds, ulcerates, or fails to heal. Seek urgent help for facial swelling with breathing difficulty or signs of a severe allergic reaction.

How certain is the diagnosis? Could another lesion look similar? Which treatment best fits my skin tone and number of bumps? What pigment changes or recurrence should I plan for? How will I care for each treated spot?
