Definition
Noun: A milium is a small, white or whitish-yellow, raised bump on the skin. It is a type of tiny cyst that forms when keratin (a protein) becomes trapped beneath the surface of the skin, often due to a clogged sebaceous gland or hair follicle. Milia are common, harmless, and not contagious.
