The bubonic plague was the disease that caused the Black Death, which killed tens of millions of people in Europe, in the Middle Ages. Symptoms of this disease include coughing, fever, and black spots on the skin.
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.
Acne happens when oil (sebaceous) glands come to life around puberty, when these glands are stimulated by male hormones that are produced in the adrenal glands of both boys and girls. The oil glands, which are located just beneath the skin, continuously produce and secrete oil through openings in the skin.
