There are a number of factors that cause acne scars. Scars are generally formed at a site of injury and are a natural result of healing. Whenever tissue suffers injury, as in the case of acne, the body rushes to the task of repairing the tissue. This repairing process is sometimes messy therefore some acne leave behind permanent scars.
Acne scars are largely classified in to two categories: Raise scars and depressed scars. Raised scars or hypertrophic scars are excess skin mass left behind on the skin surface after the acne has healed. These scars are often mistaken for acne and people often wait for the acne to heal on its own. The fact is these scars will not go away for many years to come.
The second type of acne scars are depressed scars. This is the most common form of acne scar found in people. This is when a depression is left at the spot where acne was present. Depression scars are harder to treat than raised scars. These scars form as a result of the acne getting attacked by white blood cells and some collagen being lost in the process.
Acne scars are the visual reminders of past acne that was on facial skin. Scars are caused by the spontaneous response of the body to acne lesions. These scars are treatable by various treatment methods that are available in the market. The effectiveness of various treatments varies from person to person. You must consult your dermatologist to decide which one is suitable for you.
