In the case of acne, the injury is caused by the bodys inflammatory response to sebum, bacteria and dead cells in the plugged sebaceous follicle. Two types of true scars exist, as discussed later: (1) depressed areas such as ice-pick scars, and (2) raised thickened tissue such as keloids.
When tissue suffers an injury, the body rushes its repair kit to the injury site. Among the elements of the repair kit are white blood cells and an array of inflammatory molecules that have the task of repairing tissue and fighting infection. However, when their job is done they may leave a somewhat messy repair site in the form of fibrous scar tissue, or eroded tissue.
However, when their job is done they may leave a somewhat messy repair site in the form of fibrous scar tissue, or eroded tissue. White blood cells and inflammatory molecules may remain at the site of an active acne lesion for days or even weeks. In people who are susceptible to scarring, the result may be an acne scar. The occurrence and incidence of scarring is still not well understood, however.
Well there are plenty of different types of scars-
Ice-pick scars usually occur on the cheek. They are usually small, with a somewhat jagged edge and steep sides"like wounds from an ice pick. Ice-pick scars may be shallow or deep, and may be hard or soft to the touch. Soft scars can be improved by stretching the skin; hard ice-pick scars cannot be stretched out.
Depressed fibrotic scars are usually quite large, with sharp edges and steep sides. The base of these scars is firm to the touch. Ice-pick scars may evolve into depressed fibrosis scars over time.
Soft scars, superficial or deep are soft to the touch. They have gently sloping rolled edges that merge with normal skin. They are usually small, and either circular or linear in shape.
Atrophic macules are usually fairly small when they occur on the face, but may be a centimeter or larger on the body. They are soft, often with a slightly wrinkled base, and may be bluish in appearance due to blood vessels lying just under the scar. Over time, these scars change from bluish to ivory white in color in white-skinned people, and become much less obvious. - 27772
