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.
When to expect an improvement? Any acne treatment should be continued for at least 4 weeks before there is a noticeable improvement6. There is often a good response by 6 weeks. However, it can take up to 4 months (and sometimes even longer) for maximum benefits, and for the skin to be virtually free of spots. The main reason for acne treatment failure is giving up after couple of weeks, thinking that medication is not working.
