Baby acne is very common. About 20% of newborns develop it, making it one of the most frequent skin conditions in the first weeks of life. If your baby has small red bumps or white pimples on their face, you’re likely looking at something completely harmless that will clear on its own.
When It Appears and How Long It Lasts
Baby acne, also called neonatal acne, shows up on average around two weeks of age. Some babies are born with it. The bumps are typically small, inflamed, and red or white, appearing on the face, neck, back, or chest. Most cases resolve within a few weeks without any treatment, and scarring is unlikely. Once the pimples clear, your baby’s skin will be smooth again.
What Causes It
The exact cause isn’t fully settled. Maternal hormones that cross the placenta during pregnancy are thought to stimulate oil production in a newborn’s skin, which can clog tiny pores. For years, a type of yeast that naturally lives on skin was suspected of playing a role, but research has found no clear connection between this yeast and neonatal acne. Skin colonization rates were actually higher in healthy newborns than in those with the condition. So while hormones remain the leading explanation, baby acne appears to be more of a normal adjustment to life outside the womb than a sign of infection or irritation.
Baby Acne vs. Milia
Many newborns also develop milia, tiny white bumps that look like small pearls under the skin, usually on or around the nose. Milia is present at birth, while baby acne typically appears a couple of weeks later. The key visual difference: milia are firm, white cysts caused by trapped dead skin cells beneath the surface, while baby acne looks more like classic pimples with redness and sometimes a small raised center. Milia isn’t a type of acne, and it also resolves on its own.
Baby Acne vs. Eczema
Eczema is the other condition parents commonly confuse with baby acne, but the two look and feel quite different. Baby acne presents as pimples and red spots. Eczema causes dry, scaly, inflamed patches of skin that are often rough or crusty. The biggest clue is itching: eczema itches, and you may notice your baby fussing or rubbing their face against fabric. Baby acne doesn’t itch.
Location can also help. In the first six months, both conditions favor the face, cheeks, and forehead. But between 6 and 12 months, eczema often migrates to the elbows and knees, areas baby acne doesn’t typically affect. If you’re seeing dry, flaky, or oozing patches rather than distinct pimples, eczema is more likely.
Neonatal Acne vs. Infantile Acne
If bumps appear after your baby is two months old, it may be infantile acne rather than the more common neonatal type. Infantile acne occurs between 2 months and 1 year and can look more like teenage acne, with blackheads and whiteheads in addition to red bumps. It also tends to take longer to clear. While neonatal acne almost never scars, infantile acne can be more persistent and is worth mentioning to your pediatrician, especially if it seems to be getting worse over time.
How to Care for Your Baby’s Skin
The best approach is a gentle one. Wash your baby’s face daily with warm water. You can alternate between plain water one day and water with a mild, moisturizing facial soap the next. Pat the skin dry rather than rubbing.
What not to do matters just as much:
- Don’t use lotions, ointments, or oils. These can clog pores and make baby acne worse. That includes coconut oil, olive oil, and similar home remedies that circulate online.
- Don’t pinch or scrub the bumps. This risks irritation or infection on skin that’s already sensitive.
- Don’t use adult acne products. Ingredients like benzoyl peroxide and salicylic acid can cause severe irritation or allergic reactions in infants. These products are not designed for newborn skin and can be genuinely dangerous.
In most cases, that’s all you need to do. Baby acne is a waiting game, and the bumps will fade on their own within weeks. If the acne persists beyond a couple of months, seems to be spreading, or is accompanied by unusual symptoms like fever, crusting, or oozing, it’s worth having your pediatrician take a look to rule out other conditions.
