Acne in newborns

Newborn acne: Harmless "pimples"

The appearance of tiny red pimples or white spots (milia) on the cheeks, nose, and forehead of a newborn is a very common phenomenon called newborn acne. It occurs in about 20% of infants and usually appears within the first month of life. Although this rash may look concerning, it is completely harmless, non‑contagious, and does not require treatment, resolving on its own.

Where do pimples in infants come from?

Newborn acne has nothing to do with teenage acne. Its appearance is linked to maternal hormones that the baby was exposed to in the womb. These hormones stimulate the infant’s sebaceous glands, causing them to produce an excess of skin oil. This leads to clogged pores and the rash.

It is important to distinguish newborn acne from other types of rash:

• Milia: Tiny white spots resembling pearls, most often on the nose. These are simply clogged sebaceous glands that also resolve on their own.
• Heat rash (prickly heat): Small red spots that appear in overheated areas (neck, armpits, back).
• Eczema: Dry, red, rough patches that itch.
• Allergic rash.

Care guidelines

The main rule is to not intervene. Do not try to squeeze, rub, or apply alcohol, hormonal ointments, or teen acne products to the pimples. This can cause irritation, infection, and scarring.

Care should be as gentle as possible:

• Wash the baby’s face once a day with warm water.
• Gently pat the skin with a soft towel.
• Do not use greasy creams or oils on the affected areas.

Usually newborn acne disappears completely within a few weeks or months without any trace. If the rash is very severe, inflamed, or does not resolve by 3–4 months, it is advisable to consult a pediatrician. You can read about different types of rash in our blog.
