Acne scars are caused by injury to dermal layers of the skin as a result of inflammation and rupturing of the oil glands. Your skin is disrupted by the inflammation, resulting in scaring. Therefore, to repair the scarring it is necessary to rebuild which in turn will restore an even structure to the skin. Because the cause of the scarring lies deep within the skin tissue a treatment is needed that works at this level; this is what acne laser removal does.
There are a range of different options to choose from when it comes to treatments for acne scaring. The best acne treatment for you will largely depend upon the severity of the scaring. The most suitable procedure for you will be discussed before treatment begins. Another factor that will be taken into consideration is the type of PAS (post acne scarring) that you have. Different types include: icepick scars (narrow and deep pitted scars); boxcar scars (wide depressions in the skin with clearly defined edges); rolling scars (wide depressing which have a sloping edge); and atrophic scars (these can be flat and thin or depressed).
