Nonablative Fractional Laser Therapy

Nonablative Fractional Photothermolysis Laser Therapy

The benefits of typical nonablative laser skin rejuvenation are rarely dramatic but there is minimal down time and few side effects. Whereas classic ablative resurfacing (e.g. with a CO2 laser) often have dramatic results but there are at least two weeks of down time, risks of side effects. Fractional photothermolysis is the attempt to combine the benefits of these two approaches but avoid most of the side effects. Fractional photothermolysis works by producing microscopic zones of heat-induced injury surrounded by healthy tissue whereas classic ablative resurfacing creates contiguous lesions. The density of the microscopic zones plus number of passes and total number of treatment determine the treatment outcome. There is some debate whether fractional photothermolysis is indeed superior to older nonablative infrared lasers. Two pioneer brands of nonablative fractional laser is Fraxel and Starlux. Visit our “nonablative fractional laser treatment” part for more product information. Fractional laser treatment is now also available for ablative skin resurfacing using CO2 and Er:YAG fractional laser. The advantage of ablative fractional laser is less risk of side effect and recovery time due to the fractional hundreds of microscopic microbeams that do not injure the sorrounding tissues. Both Fraxel and Starlux brand have versions of ablative laser products. Visit our “ablative laser skin resurfacing” part for more product information.

Fractional laser is a technology in which thousands of microscopic laser columns – each just one-tenth the diameter of a hair follicle – treat a fraction of the skin at a time without affecting the surrounding tissue. These laser columns stimulate the production of younger, smoother, healthier skin to replace damaged tissue. Fractional laser can be ablative or nonablative. The ablative fractional laser systems will be presented in the ablative laser resurfacing part.  Nonablative fractional laser uses infrared.
