Abstract and Classification of Acne Scars

Abstract

Acne scarring is common but surprisingly difficult to treat. Scars can involve textural change in the superficial and deep dermis, and can also be associated with erythema, and less often, pigmentary change. In general, treatment of acne scarring is a multistep procedure. First, examination of the patient is necessary to classify the subtypes of scarring that are present. Then, the patient´s primary concerns are elicited, and the patient is offered a menu of procedures that may address the various components of the scarring process. It is important to emphasize to the patient that acne scarring can be improved but never entirely reversed.

Classification of Acne Scars

There are several classifications of acne scars. A recent, comprehensive and functional scheme was proposed,1 whereby scars are classified as rolling, ice-pick, shallow box-car, and deep box-car. Rolling scars are gently undulating, appearing like hills and valleys without sharp borders. Ice-pick scars, also known as pitted scars, appear as round, deep depressions culminating in a pinpoint base; in cross-section, they are shaped like a "v.’ Box-car scars have a flat, "u-shaped’ base. Broader than ice-pick scars, they are round, polygonal, or linear at the skin surface. Shallow box-car scars terminate in the shallow-to mid-dermis, and deep box-car scars penetrate to the reticular dermis.
