Baby Acne (Neonatal & Infantile Acne)
Content reviewed against published AAP, Mayo Clinic, NIH guidelines
Last reviewed:
Baby acne is a common skin condition that causes small red or white bumps on a newborn's face. Neonatal acne (also called neonatal cephalic pustulosis) appears in the first 6 weeks of life and affects up to 20% of newborns. It is caused by maternal hormones and/or Malassezia yeast and resolves without treatment. Infantile acne, appearing at 3-6 months, is less common and may need medical management.
Key takeaways
- Baby acne is a common skin condition that causes small red or white bumps on a newborn's face.
- Most common cause: Neonatal cephalic pustulosis (Malassezia yeast reaction)
- Emergency: Widespread blistering or erosions on face in newborn under 4 weeks (rule out herpes)
- Home care: Leave it alone — neonatal acne resolves without treatment in most cases
Possible Causes
When to Seek Help
Emergency — Call 911 or go to ER:
- Widespread blistering or erosions on face in newborn under 4 weeks (rule out herpes)
- Pustular rash with fever, lethargy, or feeding difficulties in newborn
Urgent — See doctor today:
- Severe nodular or cystic acne in any infant
- Acne with signs of virilization (unusual genital development, body hair)
- Acne-like rash with baby systemically unwell
Same-day appointment:
- Infantile acne (onset 3-6 months) with comedones needing assessment
- Acne persisting beyond 4 months that parents want evaluated
- Lesions that appear infected (increasing redness, warmth, pus)
Monitor at home:
- Typical neonatal acne (small bumps on face, baby well, 2-6 weeks old)
- Milia in newborn
- Mild baby acne that is stable or improving
- Erythema toxicum in first week of life
By Age
0-2 months
Normal: Neonatal acne is extremely common, appearing as small red bumps and pustules on cheeks, nose, and forehead between 2-6 weeks of age. It peaks at 3-4 weeks and resolves by 3-4 months without scarring. Milia (tiny white bumps) are also normal.
Worry if: Severe widespread pustules (rule out neonatal herpes or bacterial infection). Acne-like lesions with fever or baby appearing unwell. Open sores or blistering rather than simple bumps. Lesions spreading to trunk and limbs in first week of life.
2-6 months
Normal: Neonatal acne typically resolves during this period. Some mild residual bumps may persist. Milia should be gone by 2-3 months of age.
Worry if: New onset of acne with comedones (blackheads/whiteheads) at 3-6 months — this is infantile acne and needs medical assessment. Nodular or cystic lesions. Acne with signs of virilization (excessive hair growth, genital changes).
6-12 months
Normal: Acne should have resolved by this age if it was neonatal type. Mild occasional pimples from drool or food irritation are common.
Worry if: Persistent or worsening acne beyond 6 months. True comedonal acne (blackheads and whiteheads) developing — needs dermatology referral. Cystic or nodular acne that could scar.
1-3 years
Normal: Acne is not expected at this age. Occasional pimples from irritation are normal.
Worry if: Any true acne in a toddler (mid-childhood acne) warrants evaluation for hormonal causes. Acne with rapid growth, body odor, or pubic hair (precocious puberty).
Home Care
- Leave it alone — neonatal acne resolves without treatment in most cases
- Gently wash face once daily with lukewarm water and mild baby cleanser
- Do NOT apply adult acne products (benzoyl peroxide, salicylic acid) to baby skin
- Avoid lotions, oils, or creams on acne areas as these can worsen it
- Do NOT squeeze, pick, or pop baby acne spots
- Pat face dry gently after washing — do not rub
- Place a soft cloth under baby's face during sleep to absorb drool/milk
- If breastfeeding, be aware that hormonal fluctuations may temporarily worsen it — this is normal
- Take comfort: baby acne does not scar and is not painful for the baby

Bottom line
Most cases of baby acne (neonatal & infantile acne) in babies are not emergencies. However, seek immediate care if widespread blistering or erosions on face in newborn under 4 weeks (rule out herpes).
Trust your instincts. If something feels wrong, reach out to your pediatrician. Worrying about your baby means you care — that is a good thing.
