What should you know about milia types?

Primary milia develop when skin cells become trapped in small cysts, commonly on the face and around the eyes. Secondary milia form after skin has been damaged or irritated, such as after a blister, rash, or procedure. The surface can look similar even though the background differs.

Some people have a few isolated bumps, while others develop clusters across the eyelids or cheeks. Milia in infants are a separate common pattern and often settle with time. A white bump is not automatically milia: whiteheads and other lesions can look alike.

Do not pick or lance any type at home. Gentle cleansing and avoiding thick, irritating products can reduce unnecessary inflammation, but these measures may not remove an established cyst. A dermatologist can discuss observation, a carefully selected topical retinoid, or controlled extraction and curettage and cautery when appropriate.

Arrange a clinical assessment if the diagnosis is uncertain, the bumps follow an injury or procedure, or they keep returning. Prompt review is sensible for tenderness, spreading redness, bleeding, crusting, quick enlargement, or changes near the eye accompanied by swelling or vision symptoms.

Ask which pattern best fits your skin, whether an earlier rash or procedure matters, and whether any treatment could worsen irritation or pigmentation. Ask how long to observe before considering removal and how to care for the area afterward.
