Baby acne looks like something is wrong with your baby's skin — but usually nothing is. AAD: it "tends to go away on its own in a few weeks to months." The key word is leave it alone.

Around 2 to 3 weeks after birth, small red bumps appear on your newborn's cheeks, forehead, and nose. Many parents panic, thinking it's a milk allergy or a soap reaction. The truth: it's baby acne (neonatal acne), and about 1 in 5 newborns get it.

The American Academy of Dermatology (AAD) [1] puts it directly: baby acne "is generally nothing to worry about. It rarely causes a scar and tends to go away on its own in a few weeks to months."

This guide draws on AAD [1] — what baby acne is, how to care for it, and when to see a doctor.

What baby acne is

Baby acne is small red bumps or pus-tipped bumps on a newborn's face. Look for:

Small red or pus-tipped bumps on cheeks, nose, forehead, chin
Sometimes spreading to the chest or back of the neck
No itch, no pain — your baby doesn't feel it
Skin around the bumps may look slightly red
Affects roughly 1 in 5 newborns (~20%)

Why it happens

The exact cause isn't fully understood — the leading theory is that maternal hormones crossing the placenta in late pregnancy stimulate your baby's oil glands, the same mechanism behind cradle cap [3]. So baby acne is not caused by:

Hygiene — it's not because you don't bathe your baby enough
Diet — not from breast milk or formula
Diaper or soap allergy
Anything you did or didn't do

Neonatal vs. infantile acne — two different windows

AAD [1] draws a clear line:

Neonatal acne — onset before 6 weeks

Typically appears around age 2 weeks
Clears on its own in a few weeks to a few months
Doesn't scar
No treatment needed

Infantile acne — onset after 6 weeks

Typically appears around age 3–6 months
Resolves within 6 months to 1 year (sometimes longer)
Can scar if left unmanaged
AAD recommends seeing a dermatologist to confirm the diagnosis and guide care

If acne-like bumps appear after 6 weeks of age, talk to your pediatrician or a dermatologist — not because it's dangerous, but to rule out other conditions like eczema or contact rash.

Home care

AAD [1] keeps the routine simple:

1. Wash with lukewarm water

Lukewarm water only — no fancy products
A soft cloth, dampened, dabbed gently on the face
Pat dry with a soft cloth

2. No scrubbing

A baby's skin is thin and easily irritated. Scrubbing makes acne worse, not better.

3. Pause oily products

Lotions, creams, or baby oils on the face can clog pores
If you've been using these, stop using them on the affected area for a while

4. Wait it out

This is the key — baby acne clears on its own without intervention. Letting your baby's skin manage itself is the best plan.

What NOT to do

AAD [1] is explicit:

"Never put acne medicine or acne wash on your baby's skin, unless your child's dermatologist or pediatrician recommends it."

Avoid:

Adult acne medication — benzoyl peroxide, salicylic acid, retinoids — too harsh for baby skin
Acne washes or toners
Squeezing or picking the bumps — risk of infection and scarring
Adult soap or fragranced products
Alcohol, lemon juice, or herbal remedies

The bumps clear on their own. Touching them only makes it worse.

Other conditions that look like baby acne

Newborns have several skin findings that can mimic acne but aren't:

Milia

Tiny white bumps on the nose, cheeks, chin — caused by trapped keratin in pores, not acne. Resolves in 2–4 weeks.

Erythema toxicum

Red blotches with white centres, common in newborns aged 2–5 days. Looks alarming but harmless. Clears in days.

Heat rash

Tiny bumps in warm/sweaty areas like the neck and back — from blocked sweat. Different from acne, which appears on the face.

Eczema (atopic dermatitis)

Dry patchy skin, itchy, sometimes weeping — different from acne, which doesn't itch and doesn't ooze.

If you can't tell which it is, your pediatrician is the right call.

When to see a doctor

Most baby acne doesn't need a doctor's visit. AAD [1] advises consulting one if:

Your baby is older than 6 weeks when bumps first appear (could be infantile acne)
Bumps haven't cleared in 3 months despite correct home care
Spreading widely beyond the face, or the bumps look like large lesions
Oozing fluid, pus, or blood
Your baby seems to be in pain or cries unusually when the area is touched
The skin around the bumps is swollen or red — possible infection

Baby acne is normal — affects ~1 in 5 newborns, caused by maternal hormones
Clears on its own in a few weeks to months without scarring (in neonatal acne)
Lukewarm water + soft cloth — that's the whole routine
Never use acne medication, adult soap, alcohol, or squeezing
Pause lotions and oils on the face while bumps are present
See a doctor if: baby is over 6 weeks at first onset · doesn't clear in 3 months · pus or red swelling

It looks more dramatic than it is. Let your baby's skin handle this on its own — clear cheeks come back soon.
