Baby acne: symptoms, treatment, and when to worry
Last updated September 3, 2026.
Baby acne is small red or white bumps on a newborn's face, usually the cheeks, nose, and forehead, appearing in the first few weeks of life. It looks alarming on perfect new skin, but it is harmless, painless for the baby, and clears on its own without treatment or scarring. Hormones passed over before birth are thought to drive it.
What does it look like?
Small red bumps, sometimes with tiny white tips, scattered over the cheeks, nose, forehead, and occasionally the scalp or neck. It tends to look worse when the baby is hot, crying, or has been rubbed by a wet cloth, and calmer at other times. It typically shows up between two and four weeks old. It is distinct from milia, which are tiny pure-white bumps present from birth, and from the red blotchy newborn rash that comes and goes in the first days.
What actually helps?
- Mostly, patience: baby acne needs no treatment and usually fades on its own over weeks to a few months. Doing nothing is the correct plan.
- Wash gently: plain warm water once a day, then pat dry. That is the whole skincare routine.
- Skip the products: no adult acne creams, no oils, no lotions on the spots. Oils and heavy products can worsen it, and adult acne ingredients are not for newborn skin.
- Never squeeze: the bumps are not poppable, and squeezing irritates skin and risks infection.
- Keep the face clean of milk: gently wipe away spit-up and drool, since residue aggravates the area.
When is it an emergency?
Baby acne is never an emergency on its own. Get a review if the spots spread beyond the face, look blistery or pus-filled, appear with a fever, or if your baby seems unwell, feeds poorly, or is unusually sleepy. A rash of tiny purple-red spots that do not fade when you press a glass to them is a same-day emergency at any age.

Common questions
What causes baby acne?
The leading explanation is hormones. Maternal hormones cross the placenta late in pregnancy and stimulate the baby's oil glands for a while after birth, producing acne-like bumps. It is not caused by anything you ate, by poor hygiene, or by breast milk on the skin, though milk residue can aggravate the look of it. It is a normal newborn variant, not a disease.
How long does baby acne last?
It typically fades over a few weeks to a few months, most resolving by around three to four months old, sometimes sooner. It often looks worse before better and fluctuates day to day. Spots still going strong well past the early months, or new acne-type eruptions starting after about six weeks to a few months, deserve a look to confirm the label, since infantile acne starting later is a slightly different beast.
Should I put anything on baby acne?
No. Newborn skin does best with warm water alone. Oils, lotions, and creams can clog and aggravate the bumps, and over-the-counter acne treatments contain ingredients not meant for infant skin. The rare severe or persistent case is assessed by a doctor, who decides whether anything is needed. Your job is gentle cleaning and resisting the urge to treat.
How do I tell baby acne from milia?
Milia are tiny, pearly white bumps, like salt grains under the skin, often on the nose and chin, present from birth or the first days, with no redness around them. Baby acne arrives a few weeks later, is red, and may have small white tips. Both are harmless and both clear without treatment, so the distinction is mostly about knowing what you are looking at rather than doing anything differently.
Can baby acne scar?
Not in the typical case. The bumps are superficial and resolve without marks as long as they are left alone. Squeezing, scrubbing, or harsh products are what create irritation and the small risk of lasting marks, which is why the hands-off advice is so consistent. Deep, persistent, or cystic-looking spots are the exception to get reviewed.
When should I worry about a newborn rash?
Worry fast about two patterns: spots that do not fade when you press a clear glass against them, which can signal a serious infection, and any rash on a baby who is also feverish, feeding poorly, floppy, or unusually sleepy. Baby acne does neither: it blanches with pressure and the baby is otherwise well. When in doubt about which you are seeing, same-day review is always the right call in a newborn.
