Much to many parent’s dismay, baby acne is so common. In fact, more than 30 percent of babies are born with baby acne or develop a rash soon after birth. Baby acne typically starts when a baby is around three weeks old, and it can last until the baby is four to six months old.

Baby acne is just one of the perfectly normal skin conditions that occur to most babies. One of the aggravators of this skin condition is the hormones that are passed to the baby before birth through the placenta. According to some studies, these hormones greatly stimulate the oil glands on the baby’s skin, thus leading to baby acne.
