Baby acne is acne that develops on a newborn's skin. Baby acne can occur anywhere on the face, but usually appears on the cheeks, nose and forehead. Baby acne is common — and temporary. There's little you can do to prevent baby acne. Baby acne usually clears up on its own, without scarring.
Pink pimples ("neonatal acne") are often caused by exposure in the womb to maternal hormones. No treatment is needed, just time. They can last for weeks or even months on baby's skin. This rash should not cause the baby any discomfort. Symptoms are usually characterized by small red or white bumps on a baby's cheeks, nose and forehead. It often develops within the first two to four weeks after birth.
Many babies also develop tiny white bumps on the nose, chin or cheeks. These are known as milia. It is very common. Between 3 and 7 in every 10 babies develop it. It seems to be more common in babies born at full term (between 37 and 40 weeks of gestation) compared with premature babies.
