Baby skin is sensitive and changes frequently. If you are noticing baby acne vs eczema: how to tell the difference, here is what you need to know.
The short answer
Baby acne and eczema can both cause facial rashes, but they look and feel different. Baby acne appears as small red or white bumps, similar to teenage acne, usually on the cheeks, nose, and forehead. Eczema causes dry, rough, red, itchy patches. Baby acne resolves on its own by 3 to 4 months, while eczema may need ongoing management.
Key takeaways
- Baby acne and eczema can both cause facial rashes, but they look and feel different. Baby acne appears as small red or white bumps, similar to teenage acne, usually on the cheeks, nose, and forehead. Eczema causes dry, rough, red, itchy patches. Baby acne resolves on its own by 3 to 4 months, while eczema may need ongoing management.
- Usually normal when: Small pimple-like bumps on a newborn's face that are not itchy and appear between 2 and 6 weeks of age
- Call your doctor if: The facial rash becomes infected with oozing, crusting, or pus
- Varies by age — see the age-by-age breakdown below
“Eczema is very common in babies and children. About 1 in 10 children will develop eczema, typically starting in the first few months of life.”
Parents everywhere have the same worry. You are doing the right thing by looking into it.
What Parents Should Know
According to AAP, AAD guidelines, baby acne and eczema can both cause facial rashes, but they look and feel different. Baby acne appears as small red or white bumps, similar to teenage acne, usually on the cheeks, nose, and forehead. Eczema causes dry, rough, red, itchy patches. Baby acne resolves on its own by 3 to 4 months, while eczema may need ongoing management. At 0-3 months, this is when distinguishing between the two is most challenging. Baby acne typically appears around 2 to 4 weeks of age as small bumps and pimples on the face. It is not itchy and does not bother the baby. Eczema tends to appear slightly later, around 2 to 3 months, and causes dry, rough patches that may be itchy. If the skin feels rough and dry, it is more likely eczema. It is generally considered normal when small pimple-like bumps on a newborn's face that are not itchy and appear between 2 and 6 weeks of age. However, you should contact your pediatrician promptly if the facial rash becomes infected with oozing, crusting, or pus.
Normal vs. Concerning
By Age
What to expect by age
0-3 months
This is when distinguishing between the two is most challenging. Baby acne typically appears around 2 to 4 weeks of age as small bumps and pimples on the face. It is not itchy and does not bother the baby. Eczema tends to appear slightly later, around 2 to 3 months, and causes dry, rough patches that may be itchy. If the skin feels rough and dry, it is more likely eczema.
3-6 months
Baby acne usually resolves by 3 to 4 months. If the facial rash persists beyond this point, it is more likely eczema or another condition. Eczema at this age often affects the cheeks and can spread to other areas. Unlike acne, eczema responds to moisturizers and may worsen with certain triggers.
6-12 months
Any persistent facial rash at this age is unlikely to be baby acne and more likely eczema, seborrheic dermatitis, or contact dermatitis. Eczema may start to shift from the face to the body and limbs. Consistent moisturizing and identifying triggers are key management strategies.
12-24 months
Infantile acne (different from neonatal acne) can rarely occur in this age group and looks more like true acne with deeper bumps. This is uncommon and should be evaluated by your pediatrician, as it may need treatment. Eczema continues to be the more common cause of facial rashes in toddlers.
What to Tell Your Pediatrician
- Describe when you first noticed baby acne vs eczema: how to tell the difference and how it has changed over time.
- Note your baby's current age and which age-specific patterns you are seeing.
- Mention if you cannot tell whether the facial rash is acne or eczema and want guidance on treatment.
- Mention if a facial rash is persisting beyond 4 months of age.
- Let your doctor know if you have noticed any related concerns, such as changes in feeding, sleep, or movement patterns.
- Bring a list of any questions or observations you want to discuss at the appointment.
What Should You Do?
When to take action
- Small pimple-like bumps on a newborn's face that are not itchy and appear between 2 and 6 weeks of age
- Mild dry patches on the cheeks that respond to fragrance-free moisturizer
- A facial rash in a newborn that does not bother the baby and is gradually improving
- You cannot tell whether the facial rash is acne or eczema and want guidance on treatment
- A facial rash is persisting beyond 4 months of age
- The rash is itchy, cracking, or spreading to the body
- The facial rash becomes infected with oozing, crusting, or pus
- Deep, cystic acne-like bumps appear on the face of a baby older than 6 months, which is unusual and may need workup
What You Can Do at Home
- Keep track of when you notice baby acne vs eczema: how to tell the difference — noting the time of day, duration, and any triggers can help your pediatrician.
- Remember that small pimple-like bumps on a newborn's face that are not itchy and appear between 2 and 6 weeks of age — this is generally within the range of normal.
- At 0-3 months, focus on observation rather than intervention unless your pediatrician advises otherwise.
- Use fragrance-free, hypoallergenic products on your baby's skin. Avoid over-bathing — 2-3 baths per week is usually sufficient.
- While monitoring at home, seek immediate care if the facial rash becomes infected with oozing, crusting, or pus.
Related Conditions
Baby Acne (Neonatal Acne)
Baby acne is a very common, harmless condition that appears as small red or white bumps on your newborn's face, usually around 2-4 weeks of age. It is caused by maternal hormones still circulating in your baby's system and clears up on its own within a few weeks to months without any treatment.
Baby Eczema (Atopic Dermatitis)
Baby eczema is extremely common, affecting up to 20% of infants, and is not caused by anything you did wrong. It shows up as dry, red, itchy patches and is very manageable with consistent moisturizing and gentle skin care. Most children outgrow it by school age.
Is It Eczema or Just Dry Skin?
Dry skin and eczema (atopic dermatitis) can look similar, but there are key differences. Simple dry skin feels rough and may flake but is not typically red, inflamed, or very itchy. Eczema causes red or darker patches that are intensely itchy, may weep or crust, and tend to appear in specific locations (cheeks and scalp in babies, elbow and knee creases in toddlers). Eczema also tends to come and go in flares, while dry skin improves consistently with moisturizer. If your baby's dry patches are itchy, red, or not improving with regular moisturizing, it may be eczema.

My Baby Has an Extra Nipple (Accessory Nipple)
Accessory (supernumerary) nipples are one of the most common minor congenital findings, occurring in about 1 in 18 people. They appear as small, flat, often pigmented bumps along the "milk line" — an embryonic line running from the armpit to the groin on each side. Most people mistake them for moles. Accessory nipples are almost always harmless and require no treatment. In rare cases, they may be associated with kidney abnormalities, so some pediatricians recommend a renal ultrasound if one is found, though this practice varies.
My Baby Was Born with a Raw Spot on Their Scalp (Aplasia Cutis)
Aplasia cutis congenita (ACC) is a condition where a baby is born with a small area of missing skin, most commonly on the scalp. It occurs in about 1 in 10,000 births. The affected area may look like a raw wound, an ulcer, or may have already healed into a thin, shiny scar by the time of birth. Most cases are small, isolated, and heal well with basic wound care — the area eventually forms a hairless scar. Larger defects or those associated with other findings may need more investigation, but isolated small ACC has an excellent prognosis.
New Treatments for Atopic Dermatitis (Eczema) in Children
Treatment for atopic dermatitis in children has advanced significantly in recent years. While moisturizers and topical steroids remain first-line treatments, newer options include non-steroidal topical medications (like crisaborole), biologic therapies (like dupilumab, approved for children 6 months and older), and JAK inhibitors. Most children's eczema is well-managed with basic skin care and mild topical treatments, but these newer options provide hope for moderate-to-severe cases.
