Neonatal acne — birth to 6 weeks of age

Neonatal acne is estimated to affect 20% of newborns. Neonatal acne takes the form of comedones (whiteheads and blackheads) that extend from the scalp, upper chest, and back, and inflammatory lesions (erythematous papules and pustules) on the cheeks, chin, and forehead. Neonatal acne can be mistaken for neonatal cephalic pustulosis.

Neonatal acne does not usually result in scarring. It is more likely to affect boys more than girls, at a rate of 5:1.
