New insight into nonablative 675-nm laser technology: current applications and future perspectives

The 675-nm laser has proven clinical effectiveness in the management of melasma, superficial melanosis, scars, and facial rejuvenation. The 675-nm laser, when used correctly, is associated with a very low incidence of side effects, mainly redness and superficial burning, that usually go away in couple of weeks. Given its histology and in vitro proven effect in stimulating collagen type III synthesis while not affecting cell viability and proliferation, this treatment may be used as a “rejuvenation” device, in order to reduce the loss of collagen during life.
