Acne scars represent a frequent complication of moderate/severe acne and may negatively impact on psychosocial and physical well-being of acne patients. Several types of acne scars have been classified and the same patient is likely to have more than one type. Each type can be treated with varying degrees of success. The main acne scars are the following:~Atrophic or Depressed Scarring:~Ice pick: An ice pick scar has a wide shaft that narrows down to the tip. It resembles a hole that's wide at the top and narrows to a point as it goes deeper into the skin. Such an indentation is common and one of the most challenging scars to heal. This scar is more frequent on forehead and upper cheeks, where skin is thinner.~Rolling: These scars are typically found on the lower cheeks and jaw, where skin is thicker. The indents have sloping edges that makes the skin look uneven and wavy.~Boxcar: Boxcar scars are indents that have sharper edges. Those edges go down deep into the skin. These scars are common on the lower checks and jaw.
