In most cases, baby acne will go away on its own within three weeks to three months. If after three months the baby acne shows no signs of improvement, parents should point out the acne at their child's wellness visit to see if there is an underlying skin condition that needs to be addressed.
Baby acne usually clears up within a few weeks, but it can linger for months. If it doesn't clear up within three months, or you're concerned about it, talk with your baby's doctor. The doctor may prescribe a mild topical medication if the acne is long lasting or severe. Persistent baby acne may be a clue that your child will deal with acne when he's a teenager, too.
