Knowing how to treat baby acne can ease the worry many new parents feel when red bumps appear on their newborn’s face. Baby acne is one of the most common skin conditions in infants, affecting up to 20 percent of newborns according to the American Academy of Dermatology (AAD). The good news is that understanding how to treat baby acne is straightforward because most cases resolve on their own with gentle care and patience.
What Is Baby Acne?
Baby acne, medically known as neonatal acne or neonatal cephalic pustulosis, presents as small red or white bumps on a baby’s skin, most commonly on the face. It typically appears within the first two to four weeks of life, though it can be present at birth or develop up to six weeks of age.
The condition appears as:
- Small red or pink bumps (papules) on the cheeks, nose, forehead, and chin
- Tiny white bumps (whiteheads or pustules)
- Redness surrounding the bumps
- Occasional spread to the scalp, neck, chest, or back
Baby acne looks similar to adolescent acne but is fundamentally different in its cause and treatment. Unlike teenage acne, baby acne does not involve clogged pores from oil production and does not require aggressive treatment.
What Causes Baby Acne?
The exact cause of baby acne is not fully understood, but several factors are believed to contribute:
Maternal Hormones
The most widely accepted theory involves maternal hormones that cross the placenta during pregnancy. These hormones, particularly androgens, stimulate the baby’s immature sebaceous (oil) glands, leading to the bumps and redness characteristic of baby acne. According to the Mayo Clinic, these hormonal effects gradually diminish as the hormones clear from the baby’s system.
Yeast Colonization
Research published in the journal Pediatric Dermatology suggests that Malassezia yeast, which naturally colonizes skin, may play a role in neonatal acne. This is why some dermatologists classify neonatal acne as neonatal cephalic pustulosis, a condition associated with yeast rather than true acne.
Sensitive Skin Reaction
A baby’s skin is extremely thin and sensitive. Exposure to saliva, milk residue, rough fabrics, or harsh detergents can irritate the skin and worsen the appearance of baby acne or cause similar-looking rashes.
How to Treat Baby Acne at Home
Most baby acne resolves without any treatment within a few weeks to a few months. However, gentle home care can help manage the condition and keep your baby’s skin comfortable.
Gentle Cleansing
Wash your baby’s face once daily with lukewarm water and a mild, fragrance-free baby cleanser. Avoid regular soap, adult facial cleansers, or acne products designed for older children and adults. Pat the face dry with a soft towel rather than rubbing. The AAD recommends using cleansers that are specifically formulated for infant skin.
Keep the Skin Dry and Clean
Gently wipe away drool, spit-up, and milk residue from your baby’s face throughout the day. These fluids can irritate sensitive skin and worsen the appearance of acne. Use a soft, damp cloth for wiping and always pat dry.
Avoid Lotions and Oils
Do not apply lotions, oils, or moisturizers to acne-affected areas unless directed by your pediatrician. These products can clog the baby’s developing pores and worsen the condition. If the surrounding skin is dry, use a small amount of fragrance-free, hypoallergenic moisturizer on non-acne areas only.
Do Not Pick or Squeeze
Never pick at, squeeze, or scrub baby acne bumps. The baby’s skin is extremely delicate, and manipulation can cause irritation, scarring, or infection. The bumps will resolve on their own as the underlying hormonal stimulation fades.
Use Gentle Laundry Products
Wash all items that touch your baby’s face, including bibs, burp cloths, sheets, and clothing, with a fragrance-free, dye-free detergent. Fabric softeners and dryer sheets can leave chemical residues that irritate sensitive skin.
Breast Milk Application
Some parents and lactation consultants recommend applying a small amount of breast milk to baby acne. Breast milk contains lauric acid, which has antimicrobial and anti-inflammatory properties. While scientific evidence for this remedy is limited, anecdotal reports are positive, and it is unlikely to cause harm. Apply a thin layer, allow it to air dry, and rinse gently during the next bath.
Manage the Environment
Heat and humidity can worsen baby acne. Keep your baby’s room at a comfortable temperature and dress them in breathable, cotton fabrics. Avoid overdressing, which can cause sweating and skin irritation.
What NOT to Do
Well-meaning advice can sometimes lead parents to harmful treatments. Avoid these common mistakes:
- Do not use adult acne products: Benzoyl peroxide, salicylic acid, retinoids, and other acne treatments designed for older children and adults are far too harsh for infant skin and can cause chemical burns, irritation, and allergic reactions.
- Do not use hydrocortisone cream: Unless specifically prescribed by your pediatrician, steroid creams should not be applied to a baby’s face. Prolonged use can thin the skin and cause other side effects.
- Do not scrub the skin: Abrasive washcloths, sponges, or exfoliating products can damage the baby’s delicate skin barrier.
- Do not apply essential oils: Tea tree oil, lavender oil, and other essential oils are too potent for infant skin and can cause allergic reactions or chemical irritation.
- Do not apply coconut oil to acne areas: While coconut oil is popular in natural parenting communities, it is comedogenic (pore-clogging) and may worsen acne in some cases.
When Does Baby Acne Go Away?
Most cases of neonatal acne resolve completely within a few weeks to three months without treatment or scarring. The timeline varies:
- Mild cases: May clear within one to two weeks
- Moderate cases: Typically resolve within four to six weeks
- Persistent cases: May last up to three to four months but almost always resolve by six months
If acne persists beyond six months of age, it may be classified as infantile acne, which is a different condition that can be more severe and may require medical treatment. Infantile acne typically appears between three and six months of age and can last until age two or beyond.
When to See a Doctor
While most baby acne is harmless and self-limiting, certain situations warrant a visit to your pediatrician or a pediatric dermatologist:
- Acne that worsens despite gentle care: If the bumps become larger, more numerous, or increasingly red despite following gentle cleansing practices
- Signs of infection: Pus-filled bumps, yellow crusting, increased redness, warmth, swelling, or fever could indicate a bacterial skin infection
- Acne that persists beyond four to six months: Prolonged acne may indicate infantile acne or an underlying hormonal condition
- Severe acne with deep cysts or nodules: This is uncommon in newborns and should be evaluated
- Acne accompanied by other symptoms: Excessive hair growth, early signs of puberty, or failure to thrive may suggest an endocrine disorder
- Uncertain diagnosis: Several other conditions can mimic baby acne, including eczema, milia, erythema toxicum, and heat rash. A pediatrician can differentiate between these conditions

Baby Acne vs. Other Newborn Skin Conditions
Several common newborn skin conditions can be confused with baby acne. Knowing the differences helps you respond appropriately:
- Milia: Tiny white bumps (not red) caused by trapped skin cells. These are not inflamed and do not need treatment. They typically appear on the nose, cheeks, and chin.
- Erythema toxicum: A benign rash with blotchy red patches and small yellow or white bumps that can appear anywhere on the body. It typically appears within the first few days of life and resolves within one to two weeks.
- Eczema (atopic dermatitis): Dry, rough, itchy patches of skin. Eczema is less likely in the first month of life and tends to appear on the cheeks, scalp, and body. Unlike baby acne, eczema benefits from moisturizer application.
- Heat rash (miliaria): Small, clear or red bumps caused by blocked sweat glands, usually in areas where clothing traps heat. Cooling the baby and removing excess clothing resolves heat rash.
- Cradle cap (seborrheic dermatitis): Greasy, yellowish, scaly patches on the scalp. While related to overactive oil glands like baby acne, cradle cap primarily affects the scalp and eyebrows.
Frequently Asked Questions
Does breastfeeding cause baby acne?
Breastfeeding does not cause baby acne. The maternal hormones that contribute to baby acne are transferred during pregnancy through the placenta, not through breast milk. Breastfeeding is safe and beneficial regardless of whether your baby has acne. For more health guidance, visit our conditions guide.
Can I put anything on baby acne?
The best approach is minimal intervention. Clean the face gently with water and a mild baby cleanser. Avoid lotions, oils, and acne products. If you want to try a natural remedy, a thin application of breast milk is generally safe. Do not apply any medication without consulting your pediatrician first.
Will baby acne leave scars?
Neonatal acne almost never leaves scars when left alone to resolve naturally. Scarring can occur if the bumps are picked at, squeezed, or scrubbed aggressively. Hands-off care is the best way to ensure smooth, clear skin after the acne resolves.
Is baby acne a sign of allergies?
Baby acne is not caused by food allergies or sensitivities. It is a hormonal condition related to maternal hormones received during pregnancy. However, if you notice other symptoms like eczema, digestive issues, or excessive fussiness, discuss possible allergies or sensitivities with your pediatrician.
Should I change my diet if I am breastfeeding a baby with acne?
No. Since baby acne is caused by prenatal hormone exposure rather than breast milk composition, changing your diet will not affect the acne. Continue eating a balanced diet and breastfeeding normally.
Key Takeaway
Baby acne is a common, harmless condition that affects up to 20 percent of newborns and typically resolves on its own within a few weeks to three months. The best treatment is gentle care: wash the face daily with lukewarm water and mild baby cleanser, keep the skin clean and dry, and avoid lotions, oils, and acne products. Never pick or squeeze the bumps. See your pediatrician if the acne worsens, shows signs of infection, persists beyond six months, or is accompanied by other concerning symptoms. With patience and gentle care, your baby’s skin will clear on its own.
