The most prominent symptoms of acne are the pimples that appear generally on the face. The most common regions of the face for the acne to appear are the cheeks, the nose and the forehead. However in extreme cases, the pimples could spread to the chest, back and the arms.

Pimples are tiny eruptions on the skin which go away within a couple of days. In some cases the pimples could develop pus in them, which would make them bigger in size and more prominent.

In general cases, the pimples disappear without any trace. But if the pimples are too severe, then they could leave behind a healing scar. Over time, this would make the face very scarred and ungainly in appearance.
