You're holding your newborn, taking in every detail, and then you notice it. Little red bumps on their cheeks, chin, or forehead. Your mind goes straight to what is that?
Take a breath. What you're most likely looking at is baby acne, one of the most common skin conditions in newborns. It's not caused by anything you did, it doesn't bother your baby at all, and in almost every case, it clears up on its own.
Here's what's actually happening — and how to know when it's worth a call to your pediatrician.
Key Takeaways
What Is Baby Acne?
Baby acne, also called neonatal acne, is a temporary skin condition that shows up as small red or white bumps, typically on the cheeks, nose, forehead, and chin. It can look alarming, especially on skin that was perfectly smooth just a week ago, but it's extremely common. Studies estimate it affects somewhere between 20 and 30 percent of newborns.
In most cases, these bumps don’t seem to bother your little ones. If they're sleeping fine and eating normally, the acne is entirely a cosmetic concern (and a short-lived one at that).
Why Does Baby Acne Happen?
The most straightforward answer: hormones.
During the final weeks of pregnancy, a surge of maternal hormones crosses the placenta to your baby. Those hormones continue circulating in your newborn's system after birth, and one of their effects is stimulating the sebaceous (oil) glands in their skin. When those glands get overactive, clogged pores follow, and so do the bumps.
Some research also points to a naturally occurring yeast (Malassezia) on newborn skin as a contributing factor, which is why you may see baby acne referred to as neonatal cephalic pustulosis in clinical literature. But for most parents, the short version is this: their body is still adjusting to being on the outside, and their skin is catching up.
Worth noting: baby acne has nothing to do with your diet (if you're breastfeeding), your baby's hygiene, or anything in their environment. It's biology, not a sign that something’s wrong.
When Does Baby Acne Show Up — and When Does It Go Away?
Baby acne typically appears between two and four weeks of age, though it can show up as early as the first week or as late as six weeks. It often looks worse before it gets better. New parents have been known to do a double take at the two-week mark.
The good news: most cases resolve on their own within a few weeks. Some babies clear up by eight weeks; others may have lingering spots for a few months. Either way, it almost always resolves completely without treatment or scarring.
One thing that can make baby acne look worse temporarily: heat, friction (from clothing or car seats), or skin contact with drool or spit-up. That’s just an already-irritated skin barrier getting a little more inflamed.
What You Should NOT Do
This is where a lot of well-meaning parents go wrong.
Don't scrub or exfoliate. Newborn skin is thin and sensitive. Scrubbing the affected areas won't clear them up; it'll just irritate the skin further.
Don't use acne treatments or medicated products. Adult or teen acne products — anything with benzoyl peroxide, salicylic acid, or retinoids — should never go on a newborn's skin. These formulas are far too strong.
Don't apply lotions, creams, or oils to the bumps. It's tempting to "treat" something by moisturizing it, but adding any product to the affected area can clog pores further and make things worse.
Don't pop or squeeze. (We know you won't. But just in case: please don't.)
The actual best thing you can do for baby acne is leave it alone. Wash your baby's face gently with plain warm water once a day, pat dry, and let the hormones work their way out of their system.
Baby Acne or Something Else?
Not every rash on a newborn is baby acne. A few other common conditions are worth knowing:
Milia are tiny white bumps (not red) that often appear on the nose and cheeks. Very common in newborns, also hormone-related, and also self-resolving.
Eczema typically shows up a little later, usually after two months, and looks more like dry, scaly, or rashy patches. It can itch, which means your baby may seem uncomfortable. Eczema usually requires more targeted care, so talk to your pediatrician if you think that may be the issue.
Heat rash shows up as small red bumps or blisters in warm, sweaty areas. It usually resolves once the skin cools down.
Cradle cap is yellow, crusty scaling on the scalp, which sometimes also spreads to the face. Different texture than baby acne and an entirely different condition.
If you're unsure what you're looking at, your pediatrician can identify it quickly at any regular visit. No need to make a special appointment unless other symptoms are present.
When to Call Your Pediatrician
Baby acne doesn't usually require a doctor visit. But reach out to your pediatrician if:
-
The bumps are spreading beyond the face to the neck, chest, or body
-
The skin looks swollen, feels warm to the touch, or shows signs of infection
-
Your baby seems uncomfortable or is scratching at their face
-
The rash appears in the first two weeks of life (very early rashes may need evaluation to rule out other causes)
-
The bumps haven't improved at all after three months
Infant acne that appears after six to eight weeks of age — sometimes called infantile acne — can be a different condition and may warrant a closer look, since it can occasionally indicate an underlying hormonal issue.
When in doubt, ask. Pediatricians field these questions constantly, and would rather you call than sit home worrying.
A Note on Their Skin in These Early Weeks
Newborn skin is doing a lot of work right now. It's adjusting to a completely new environment — air, temperature, clothing, friction — after months in an entirely different one. Baby acne is just one of several normal skin events in the first few months, alongside peeling, milia, and early dryness.
The gentlest thing you can do for your baby's skin is keep it clean, dry, and free of unnecessary products. For everything else, including what your baby sleeps on, choosing materials that are genuinely clean matters. Newton's products are made without foam, glue, latex or springs, and GREENGUARD Gold Certified for low chemical emissions, because what's touching your baby's skin and breathing space all night adds up.
But for baby acne specifically? The best treatment is time. And a lot of it passes faster than you think.
