What should you know about secondary milia treatment?

Secondary milia are superficial cysts filled with keratin that develop after skin has been injured or inflamed. They may follow a burn, blister, rash, abrasion or cosmetic procedure. The bumps are often smooth, firm and pale, and they can remain in place while the surrounding skin settles.

A clinician checks the bumps rather than assuming every white spot is milia. Whiteheads and other skin bumps can look similar but need different care. The treatment plan therefore starts with the appearance, skin history and any active inflammation.

If the cysts are few and not bothersome, observation may be reasonable while the skin recovers. A clinician can open and remove an individual cyst with a sterile technique. Curettage and cautery may suit selected lesions, while a prescribed topical retinoid may be discussed when there are multiple or recurring bumps. Avoid picking and use gentle cleansing during healing.

For context, see [Milia](/conditions/milia/), [Whiteheads](/symptoms/whiteheads/) and [Topical Retinoids](/treatments/medical-dermatology/topical-retinoids/).

Book a dermatology review for lesions that persist, spread, itch intensely, hurt, crust, bleed or change colour. Seek quicker medical advice if redness, warmth, swelling or discharge develops after removal, as these may signal infection. Vision changes or a lesion on the eyelid also warrant prompt assessment.

Ask what triggered the secondary milia, whether the diagnosis is certain, and whether treatment is needed now. Discuss the expected healing process, pigment changes or marks that might occur, suitable products, and how to reduce further irritation.
