Non-ablative fractional resurfacing of surgical and post-traumatic scars.

Objective: Non-ablative, fractional lasers generate microscopic columns of coagulated tissue through the epidermis and dermis to evoke a wound healing response. In this study, the authors examined the efficacy and safety of the non-ablative 1540 nm erbium:glass fractional laser in the treatment of surgical and post-traumatic scars.

Methods: Clinical studies were conducted on a range of surgical and post-traumatic scars with a 1540 nm erbium:glass fractional laser varying energy, pulse widths, treatment passes, and number of treatments.
