Baby acne is completely normal. It affects about 20% of newborns, making it one of the most common skin conditions in the first weeks of life. The small bumps typically appear around two weeks of age, look more alarming than they are, and almost always clear up on their own without any treatment.
What Causes It
Despite the name, neonatal acne isn’t actually “true” acne the way teenagers and adults get it. It’s an inflammatory response to a type of yeast called Malassezia that naturally lives on human skin. This yeast begins colonizing a baby’s skin at birth and increases over the first several weeks of life. Combined with the hormonal environment of a newborn (residual hormones passed from the mother during pregnancy stimulate the baby’s oil glands), the result is small bumps that look a lot like pimples but form through a different process.
What It Looks Like
Baby acne shows up as small white pimples or red spots, most often on the cheeks, forehead, and chin. It can also appear on the scalp, neck, upper back, and chest. The bumps are usually tiny and clustered, without the blackheads or deeper cysts you’d see with acne in older children or adults.
Two other common newborn skin conditions can look similar:
- Milia are tiny white cysts just under the skin’s surface, caused by trapped keratin. They’re firm, pinpoint-sized, and don’t look inflamed or red. Nearly half of all newborns get them.
- Eczema looks different in texture. It causes dry, rough, or scaly patches that may appear red and weepy. In babies under six months, it tends to show up on the face and scalp, much like acne, but the skin feels rough rather than bumpy, and it itches. Eczema does not appear in the diaper area.
If the bumps are smooth white dots with no redness, you’re likely looking at milia. If the skin is dry, flaky, or seems to bother your baby, eczema is more likely. Baby acne sits in between: red or pink bumps, sometimes with a white center, on otherwise normal-feeling skin.
When It Appears and How Long It Lasts
Baby acne can be present at birth but more commonly shows up before a baby turns two months old, with the average onset around two weeks. It’s temporary. Most cases clear within a few days to a couple of weeks, though some take up to a month to fully resolve.
There’s also a less common form called infantile acne, which appears between roughly 6 weeks and 12 months of age. Infantile acne looks more like traditional acne, sometimes including blackheads, whiteheads, and even small cysts. It takes longer to resolve, typically clearing within 6 to 12 months. Most cases are still mild to moderate and don’t need treatment, but infantile acne is worth mentioning to your pediatrician since it occasionally needs monitoring.
How to Care for Your Baby’s Skin
The short answer: do very little. Baby acne doesn’t need creams, special cleansers, or any intervention. Overwashing or applying products can irritate delicate newborn skin and make things worse.
A few simple guidelines help:
- Wash gently with water. Use a soft, moist washcloth to clean your baby’s face without soap. Start at the bridge of the nose and wipe outward around each eye, then gently go over the rest of the face.
- Skip adult products entirely. Soaps, lotions, and cleansers made for adults are too harsh and can contain irritants or allergens. Even baby lotion isn’t necessary unless the skin is genuinely dry.
- Bathe less than you’d think. Most newborns only need a bath about three times a week. Between diaper changes and face wipes after feedings, that’s plenty.
- Don’t squeeze or scrub. The bumps aren’t clogged pores in the way adult acne is, so popping or scrubbing won’t help and risks irritating or infecting the skin.
- Avoid powders near the face. Airborne powder particles can irritate a baby’s lungs and skin.
When bathing, keep the room around 75°F to prevent drafts, and test the water temperature against the inside of your wrist or elbow. It should feel warm, not hot.
Signs That Need a Closer Look
Standard baby acne doesn’t cause discomfort. Your baby shouldn’t seem bothered by it, and the skin between the bumps should look and feel normal. A few situations are worth bringing up at your next pediatric visit: bumps that persist beyond six weeks of age (which may indicate infantile acne rather than the neonatal type), skin that appears crusty, oozing, or scaly, breakouts accompanied by fever, or bumps that seem to be spreading to unusual areas like the diaper region. These patterns don’t necessarily signal anything serious, but they can point to other conditions like eczema or a skin infection that benefit from a proper evaluation.
