Neonatal acne (also known as "Acne infantum,"
"Acne neonatorum", and "Neonatal cephalic pustulosis” (not
to be confused with "Benign cephalic histiocytosis")) is an acneiform
eruption that occurs in newborns or infants, and is often seen on the nose and
adjacent portions of the cheeks.
The main cause of this condition is not known, but it could
be due to the increased sensitivity of the infant's sebaceous glands to
maternal hormones during pregnancy which also leads to a variety of skin
conditions in the newborn.Typically, it peaks at around 2 months and rarely
needs treatment. Sometimes gels or ointments are given.
