A large number of adolescents have to deal with acne problems, especially around the onset of puberty. Some individuals, however, have a more serious issue with their acne than others.

These cysts can burst open and then get infected easily, ultimately scarring the skin that has been affected so seriously that the scars are nearly impossible to get rid of.
