Infant acne usually pops up when babies are between 2 weeks and 2 months old. It may last up to age 6 months, or it may disappear within a couple of weeks just as quickly as it came. Infant acne most often occurs on the face and can be in the form of small whiteheads.
Causes
Infant Acne is caused by the hormones in your system that the baby has acquired in utero or from your breast milk. Symptoms will usually disappear when the hormones are eventually cleansed from the baby’s system
