Neonatal acne is a newborn eruption from birth to 6 weeks that usually clears without scarring within weeks to about 3-4 months. Current evidence supports observation for typical mild cases and prompt clinician review for persistent, severe, or scarring lesions.
It is a common newborn finding, estimated by DermNet to affect about 20% of newborns DermNet overview of acne in children. Typical breakouts involve the cheeks and nose and may also affect the forehead, chin, scalp, neck, back or chest. The American Academy of Pediatrics places onset usually during the third to fifth week of life.

What does it look like?
DermNet describes whiteheads and blackheads on the scalp, upper chest and back, plus red papules and pustules on the cheeks, chin and forehead. Whiteheads and blackheads are small plugged pores, while papules and pustules are red bumps, some with pus.
A related rash, neonatal cephalic pustulosis, looks different. DermNet reports it erupts on the face or scalp often during the third week as pustules without blackheads or whiteheads. That absence of comedones helps clinicians separate the two conditions.
What causes these newborn breakouts?
DermNet attributes neonatal acne to maternal and neonatal androgens stimulating sebaceous glands. Androgens are sex hormones present in mother and baby, and sebaceous glands are the skin oil glands they activate.
DermNet links cephalic pustulosis instead to Malassezia colonization found on pustule smears DermNet review of neonatal cephalic pustulosis. Malassezia is a yeast commonly found on skin. This distinction matters because the two rashes share timing but not cause.
How long does it last?
DermNet describes the eruption as self-limited and generally resolving spontaneously without scarring within weeks to about 3-4 months DermNet guide to blisters and pustules in neonates. Benign neonatal pustular disorders require no specific treatment under that assessment.
For parents, the practical decision is monitoring rather than active treatment. Mild cheek pimples in a comfortable, feeding newborn fit the expected course. Change in spread, severity, or healing changes the decision.
When should you get an exam?
Visual diagnosis is limited because neonatal acne can be mistaken for cephalic pustulosis and other neonatal rashes. DermNet advises clinician assessment for persistent, severe, or scarring lesions rather than diagnosis by appearance alone.
