Acne affects as much as eighty percent of teenagers and others in their early twenties, while leaving most with only a few minor scars from acne, some even without any at all; there is also a notable percentage that suffers from acne scars.
There are two types of skin problems caused by acne that can be recognized as acne scars, one is the red pigmentation that appears after acne has healed. These are post-inflammatory lesions which occur as the acne heals, and these may be present for up to 6-12 months. However if the pigmentation that you see lasts longer than the period stated, you may be experiencing acne scars.
Acne scars come from connective tissue that the body uses to repair the damage done to a certain area. Together with antibodies and white blood cells, working together to heal the wound. After healing, you are left with a scar.
Acne scars can develop as acne is present, so a good form of prevention is actually preventing acne. However, acne scars can also be prevented even in the presence of acne. This is done to facilitate healing of acne, the faster it gets healed, the less the acne scar will need to be treated, or may not need any treatment at all.
Without the complicated chemicals and difficult dermatological treatments, you can also help prevent acne scars treating your skin righteously. Avoid sun exposure, this can cause further skin damage and may hamper the healing process of your skin. Wear sunscreen that has SPF 15 or higher. Picking at scabs never helped either.
