Also Known As: Acne scars, Ice pick scars, Box car scars, Rolling scars
Acne scars are the result of inflammation within the dermis brought on by acne. The scar is created by the wound trying to heal itself resulting in too much collagen in one spot.[medical citation needed] Physical acne scars are often referred to as "ice pick" scars. This is because the scars tend to cause an indentation in the skin's surface. There is a range of treatments available. Although quite rare, the medical condition atrophia maculosa varioliformis cutis also results in "acne-like" depressed scars on the face.
