Milia, often referred to as “milk spots,” are small, white or yellowish cysts that commonly appear on the skin. These tiny bumps are typically painless and can occur in people of all ages, from infants to adults. Milia are caused by the buildup of keratin, a protein that is naturally present in the skin.

While they are generally harmless, milia can be a cosmetic concern for some individuals, particularly when they appear on the face. In this article, we will explore 15 potential causes of milia, shedding light on the factors that can contribute to their development.
