Milia are 1-2 mm keratin cysts in the skin that are seen as small bumps. They are most common on the face, but can occur anywhere. They are also seen in connection with some skin diseases.
Milia usually form spontaneously; without any particular reason. They are also seen after burns during the healing phase and in several blistering diseases. Rarely, drugs are a cause.
Milies are of purely cosmetic importance. They can be opened carefully with a small scalpel incision and emptied. Burning and lasers are also used. The method of removal depends slightly on the number of milia and the practitioner's preference. Often, drained milia will stay away.
