Milia

What are milia?

A milium cyst is small, white bump that typically appears on the nose and cheeks. These cysts are often found in groups, and in these cases are called milia. The cysts occur when keratin becomes trapped beneath the surface of the skin. Keratin is a strong protein that is typically found in skin tissues, hair, and nail cells.

What causes milia?

Milia can appear for no particular reasons. However, they are typically associated with some type of damage to the skin.
