Milia types are grouped by when the cyst forms or what causes it.
Neonatal milia show up in babies and clear in a few weeks. The cysts are usually on the face, scalp, and upper body. About 40% of newborns get them.
Rare genetic disorders can lead to juvenile milia.
This type is linked to genetic or autoimmune skin issues and affects the eyelids, ears, cheeks, or jaw. It’s often seen in middle-aged women but can be in anyone.
This milia type is in older kids and adults. The cysts can be around the eyelids, forehead, or genitals. They might go away in a few weeks or last months.
Milia can sometimes pop up where the skin is hurt, like with a rash or sunburn. The cysts might get red around the edges and white in the center.
