Milia is a blockage of the sweat gland. It is a keratin-filled cyst that can appear just under the epidermis. They are very small, raised, pearly-white bumps on the skin. They are most often seen on the skin around the cheeks, nose, eyes and eyelids, forehead and chest. However, they can occur anywhere on the body.
Milia are very common in newborn babies but can affect people of any age.
