Laser light therapy is another effective way of preventing scarring with chronic acne cases. It has also been used in healing breakouts as well. After a few treatments with a nonabrasive laser surgery, the scars that remain from bad acne breakouts can be treated. This is due to the collage growth that is promoted under the scars. Treatments range from five to twenty minutes and there is usually only slight discomfort. There is marked improvement in skin after only a few treatments. There are a few side effects such as mild redness and swelling for a short amount of time, but it does not interfere with the patient’s life.
