Milia most commonly appear across a baby’s nose, chin or cheeks. Although milia can develop at any age, these tiny white bumps are common among newborns.
They are formed when keratin (a substance produced by the skin) becomes entrapped beneath the outer layer of the skin, forming a tiny cyst. An individual milium (the singular of milia) is formed at the base of a hair follicle or sweat gland.
Milia can heal on their own or see a dermatologist for professional removal.Back to Glossary
