The 1540-nm Nonablative Fractional Photothermolysis for Facial Surgical Scars

Abstract

Introduction: Nonablative fractionated photothermolysis creates microscopic zones of thermal damage extending down into the dermis. The epidermis is left intact, allowing for rapid healing with minimal downtime for the patient. The deep heating of the dermis can help with rejuvenation of the skin by promoting neocollagenesis. The purpose of this study is to evaluate the effectiveness of 1540-nm nonablative fractional photothermolysis for facial surgical scars. Materials and Methods: Four patients with varying Fitzpatrick skin types had facial surgical scars treated with a 1540-nm nonablative fractionated photothermolysis. Results: All patients showed marked improvement in the appearance of their scars with no adverse pigmentary changes. The 1540-nm nonablative fractional resurfacing laser should be considered a first-line treatment for postsurgical scarring. Conclusions: Nonablative fractional photothermolysis with a 1540-nm wavelength is an excellent method to improve the appearance of facial surgical scars. It can be done with a minimum amount of downtime and should be safe for all skin types.
