Neonatal Acne

Promo: Overview of neonatal acne: a common newborn rash
Neonatal acne is a very common skin rash affecting up to 1 in 5 newborns. As a board-certified
pediatrician, Dr. Sima Stein sees babies from just after birth through their newborn periods and into infancy. During this time, babies can experience many types of rashes, most of which are benign and
transient, though sometimes require additional testing. Below are common questions and answers regarding the cause, presentation, and treatment of neonatal acne.
When does neonatal acne present and what does it look like?
Neonatal acne usually presents 2-4 weeks after birth and looks like red and white bumps on the forehead,
nose, and cheeks. It can also present on other areas of the body but is most commonly found on the face.
Typically these lesions resolve over the course of weeks to months and do not result in residual scarring like traditional acne can. Neonatal acne is also not known to be a precursor for teenage or adult acne.
What causes neonatal acne?
Neonatal acne is thought to result from the stimulation of sebaceous glands by maternal and infant hormones. Sebaceous glands are small glands in the skin which secrete sebum, an oily material which
keeps the skin and hair lubricated, but also promotes the development of acne. Additionally, it is theorized that a build-up of yeast can be linked to neonatal acne, though this yeast is normally found on human skin and is not related to over or under bathing the newborn.
How is neonatal acne treated?
Generally no treatment is needed, though your pediatrician may recommend a gentle moisturizer. It isimportant to keep the skin dry and cleanse the skin as needed with warm water and a mild, non-scented baby soap. If the lesions are extensive or persist for several months, a 2.5% benzoyl peroxide lotion may
be indicated, though it is advised you talk to your pediatrician before initiating this treatment as it can cause allergic reactions in some patients and may not be appropriate depending on the patient. Some families may try application of breast milk to rashes during the newborn period. Though breast milk has
multiple favorable effects, it has not been shown to treat neonatal acne.
