Acne scars are the dark and sometimes swollen pits left in the skin long after the pimple has healed and are divided into four categories according to appearance and cause: ice pick (small pits), boxcar (scars that have sharp edges), rolling (caused by damage underneath the epidermis) and hypertrophic (raised and bumpy because of excess scar tissue under the skin).
