What are acne scar?
Acne scars are permanent textural changes and indentations that occur on the skin as a result of severe acne. The term “scarring” is not used for the temporary red and brown marks left early after acne has occurred as these marks will almost always improve without treatment.
What causes acne scarring?
In severe acne, large pus-filled spaces known as acne cysts are formed. These cysts destroy skin tissue which is not replaced during the healing process. When the cyst eventually empties and the area heals, it usually leaves behind an indentation (or scar) on the face. On the chest and back the scarring can be lumpy (known as “hypertrophic” or “keloid” scarring).
What does acne scarring look like?
Acne scarring on the face appears as damage to the skin texture with depressed (or indented) areas of various sizes. On the back and chest, scars tend be raised and lumpy. Scars are usually a normal skin colour. Some keloid scars can remain red for many years.
