Milia are tiny white bumps or small cysts on the skin. They are almost always seen in newborn babies.
Milia occur when dead skin becomes trapped in small pockets at the surface of the skin or mouth. They are common in newborn infants.
Similar cysts are seen in the mouths of newborn infants. They are called Epstein pearls. These cysts also go away on their own.
Adults may develop milia on the face. The bumps and cysts also occur on parts of the body that are swollen (inflamed) or injured. Rough sheets or clothing may irritate the skin and mild reddening around the bump. The middle of the bump will stay white.
Irritated milia are sometimes called "baby acne." This is incorrect since milia are not a true from of acne.
Symptoms may include:
In children, no treatment is needed. Skin changes on the face or cysts in the mouth often go away after the first few weeks of life without treatment. There are no lasting effects.
Adults may have milia removed to improve their appearance.
There is no known prevention.
