The Bottom Line

Baby acne is very common — about 1 in 5 newborns gets it. It shows up as small red or white pimples on the face in the first few weeks of life. It is caused by hormones passed from mom to baby during pregnancy, not by dirty skin. Almost all cases clear up on their own within 2–4 months, leaving no scars. There is nothing you did wrong, and your baby will be fine.

What Is Neonatal Acne?

Neonatal acne (also called "baby acne") is a common skin condition in newborns that causes small pimples and pustules on the face. It affects about 20% of newborns — that is roughly 1 in 5 babies. It typically appears within the first 2–4 weeks of life and almost always clears on its own by 3–4 months of age.

Boys are slightly more affected than girls (about a 5:3 ratio) because they are more sensitive to certain hormones. Having family members with severe acne may slightly increase the chances, but most cases have nothing to do with family history.

What Does Neonatal Acne Look Like?

  • Small red or white pimples (pustules), typically 1–3 mm in size
  • May also include small raised bumps (papules)
  • Occasionally, tiny blackheads or whiteheads (comedones)
  • Most common on the cheeks, forehead, chin, and around the nose and mouth
  • Not itchy, not painful
  • Does NOT cause scarring

What Causes Baby Acne?

Before birth, your baby is exposed to hormones (mainly androgens) from your body. These hormones stimulate the oil glands in your baby's skin, especially on the face. When those oil glands make too much oil and a pore gets blocked, a pimple forms.

After birth, your hormone levels in your baby drop, but the oil glands stay active for a few weeks. This is why baby acne usually peaks in the first month and then fades on its own as hormone levels settle down.

A related condition called neonatal cephalic pustulosis may look similar but is triggered by a naturally occurring yeast (Malassezia) on the skin rather than hormones. It may respond better to gentle antifungal treatment.

How to Care for Your Baby's Skin

The most important thing to know: less is more. Here is what to do — and what to avoid:

Do:

  • Wash your baby's face gently with lukewarm water once or twice a day
  • Pat dry — do not rub
  • Use only mild, fragrance-free cleansers formulated for babies

Do not:

  • Scrub or squeeze the pimples — this can irritate your baby's delicate skin
  • Apply adult acne products (benzoyl peroxide, salicylic acid) without a doctor's guidance — these can absorb too easily through newborn skin
  • Use lotions or oils on the acne-affected areas — they can make it worse

Treatment Options

Most cases of neonatal acne need no treatment at all — just gentle skin care and patience. Your baby's skin will clear up on its own.

If the pimples persist beyond 4–5 months or are more severe, a doctor may recommend:

  • Azelaic acid 20% cream or lotion — safe and effective for infants, applied twice daily to reduce inflammation
  • Clindamycin 1% lotion — a mild antibiotic option for persistent cases
  • Ketoconazole 2% cream — if neonatal cephalic pustulosis (yeast-related) is suspected

The prognosis is excellent: about 90% of cases resolve completely by 3–4 months of age with no lasting marks.

When to See a Dermatologist

  • Pimples persist beyond 4–5 months without improvement
  • Lesions are getting larger, more numerous, or deeper (cystic)
  • Signs of infection: increasing redness, warmth, swelling, or discharge
  • Rash extends to the scalp, body, or limbs (this may be a different condition)
  • You are unsure whether it is baby acne or something else
  • You are feeling very distressed about your baby's appearance

Frequently Asked Questions

Is baby acne contagious?

No. Neonatal acne is not contagious at all. It is caused by your baby's own oil glands responding to hormones — you cannot catch it from your baby, and your baby cannot spread it to siblings or caregivers.

Does baby acne mean my child will have bad acne as a teenager?

No. Having neonatal acne does NOT increase the risk of severe acne in the teenage years. The two conditions are separate. Neonatal acne is a normal newborn response to maternal hormones. Teenage acne is driven by different factors.

Can I put breast milk on baby acne?

Some parents try this as a home remedy. There is no strong scientific evidence that it helps, but it is unlikely to cause harm. The most important things remain gentle cleansing and leaving the pimples alone. If you try breast milk, make sure the skin is clean and dry first.

How do I know if it is baby acne or something more serious?

Baby acne is limited to the face, appears in the first 2–4 weeks, does not cause fever or fussiness, and clears within 2–4 months. If your baby has pustules spreading beyond the face, has a fever, seems unwell, or if you see blisters (fluid-filled bumps) rather than pimples, call your doctor right away — these may be signs of a different condition that needs prompt attention.
