Acne Scar Laser
Laser stands for Light Amplification by Stimulated Emission of Radiation. Acne scar laser treatment is usually for those with shallow and deep scars after having suffered from acne. In most cases, it is not recommended for those with active acne. Acne scars are in general not reversible; however, there are treatments available to remove these scars, and acne scar laser is one of them.
Acne scar laser involves emitting low-divergence radiation or beam through “stimulated emission”. Special lenses are used to control the beam. There are two types of laser beams are used: erbium YAG laser and carbon dioxide laser. The latter is the modern type of laser treatment that has replaced the former. In the treatment, laser rays are applied to the affected areas and effectively burn out scars within seconds of exposure. In addition, it also kills the bacteria that cause acne, and retards the operation of sebaceous glands that produce sebum, the oily substance that produces acne. The burning process would create mild wounds, which in most cases would not cause bleeding. When the wounds heal, the dead cells of the skin would get replaced with fresh cells which would be scar free. Pen devices are used during acne scar laser treatment; the intensity level of the beam is adjustable to match the condition of the scars that have to be treated. For instance, deep scars require higher intensity levels than those with mild surface scars. The burning sensation caused by the strong laser beam is usually relieved by means of cooling sprays.
It is rare to get scar free skin in one session of acne scar laser treatment. It may require between 8-15 session, with each session takes about 15-20 minutes. The number of sessions required is dictated by the severity of the acne scars and the skin type. Laser treatment is considered quite efficacious for removing acne scars.
However, there are also risks or side effects due to this kind of treatment. For instance, if it was not done properly it may cause skin irritation, thermal damage to the skin, hyperpigmented macules (spots), changes in the pigmentation or even long-term dryness of the skin. The treatment may not be suitable for the faint-hearted people because it causes a lot of mess in form of blood effusion. The peeled skin may become raw and red and causes pain for quite some times. Further acne on laser treated areas can worsen the condition.
Despite these side effects, however, acne scar laser is considered effective as one of acne removal treatments available today.
