Perioral Dermatitis in Babies
The short answer
Perioral dermatitis causes small red or pink bumps around the mouth, nose, and sometimes eyes. In babies, it is often confused with drool rash or eczema. While drool rash typically clears with barrier cream, perioral dermatitis may need specific treatment from your pediatrician. It is not harmful and does not scar, but it can take time to resolve.
By Age
What to expect by age
Rashes around a newborn's mouth are more commonly baby acne, milia, or eczema rather than true perioral dermatitis. Newborn skin goes through many normal changes in the first weeks. If you see small bumps around the mouth area, keep the area clean and dry, and avoid applying heavy products. Mention it at your next well visit if it does not clear.
As drooling increases, it can be hard to distinguish drool rash from perioral dermatitis. Drool rash is flat redness where drool sits, while perioral dermatitis has distinct small bumps often with a clear zone right against the lip border. If a rash around the mouth does not respond to barrier cream and gentle care within 2 weeks, bring it up with your pediatrician.
Perioral dermatitis can be triggered by the use of topical steroids on the face (even low-potency ones), thick ointments, or fluoride toothpaste. If your baby has been prescribed a steroid cream for eczema and develops new bumps around the mouth, let your doctor know. Treatment may involve stopping the steroid and using a gentle alternative.
In toddlers, perioral dermatitis may come and go. Avoid using steroid creams on the face without doctor guidance, and use only mild, fragrance-free products. Treatment options your pediatrician may suggest include topical antibiotics or gentle anti-inflammatory creams. The condition is cosmetic and not contagious.
What Should You Do?
When to take action
- Mild redness around the mouth from drool that clears with barrier cream
- Small bumps that come and go without other symptoms
- Rash that does not seem to bother your baby
- Slight irritation after eating messy foods that resolves quickly
- Bumps around the mouth persist for more than 2 weeks and do not respond to gentle home care
- The rash seems to be spreading or getting worse, especially if you have been using steroid cream
- Bumps are present around the mouth, nose, and eyes in a distinct pattern
- The rash becomes blistered, weepy, or crusted with honey-colored scabs suggesting a bacterial infection like impetigo
- Your baby develops mouth sores, fever, or refuses to eat along with the facial rash

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 Blister on Lip from Nursing
A nursing blister (also called a suck callus) is a small, painless blister or thickened patch on your baby's upper lip caused by the friction of latching during breastfeeding or bottle feeding. It is completely harmless, does not hurt your baby, and does not need any treatment. These are very common in newborns and typically come and go in the early weeks.
Baby Chin Rash from Drooling
Drool rash is extremely common and appears as red, irritated, or slightly bumpy skin on the chin, cheeks, neck, and chest where drool sits. It is caused by the constant moisture and digestive enzymes in saliva irritating the skin. Keeping the area dry and applying a barrier like petroleum jelly before drool exposure is the most effective treatment.
Baby Dry Patches on Cheeks
Dry patches on your baby's cheeks are very common, especially during cold or dry weather. Baby skin is much thinner and more sensitive than adult skin and loses moisture easily. In most cases, regular application of a gentle, fragrance-free moisturizer is all that is needed. If patches are red, rough, or itchy, mild eczema may be the cause.
Baby Ingrown Toenail
Ingrown toenails are fairly common in babies and toddlers, especially on the big toe. Baby toenails are soft and can easily curve into the surrounding skin. Most mild cases improve with warm soaks and gentle care. If the toe becomes very red, swollen, or shows signs of infection, your pediatrician can help with treatment.
Baby Nail Peeling or Splitting
Peeling or splitting nails in babies are very common and usually harmless. Baby nails are extremely thin and soft, making them prone to peeling, especially from normal wear and moisture exposure. This typically improves as your child grows and their nails become stronger. Keep nails trimmed short and moisturize the nail area gently.
