Study reports that the 2910 nm erbium-doped fluoride glass fiber laser is safe and effective for improving the appearance of acne scars.
Wausau, WI (September 24, 2024)—Acne scarring is a very common problem, and a new laser enables new types of pulses to improve acne marks in patients. This clinical report investigates the 2910 nm erbium-doped fluoride glass fiber laser, which can deliver approximately 5,000 pulses per second for the treatment of acne scarring.
The study, led by Eric F. Bernstein, MD, MSE, is titled “The 2910-nm Fiber Laser Is Safe and Effective for Improving Acne Scarring.” The clinical report, published in Lasers in Surgery and Medicine (LSM), the official journal of the American Society for Laser Medicine and Surgery, Inc. (ASLMS), was selected as the September 2024 Editor’s Choice.
“This study investigates a new type of fiber laser with an extremely high repetition rate, which enables unique pulse-structures, for the treatment of acne scarring,” Bernstein said. “This study is important because acne scarring is a very common problem, and we are constantly looking for new ways to improve these marks and help our patients.”
Fourteen subjects were enrolled in the study, with thirteen completing the study and receiving three treatments administered at 6–8-week intervals. Digital images were taken pre- and 1- and 3-months posttreatment and evaluated by two blinded reviewers in a randomized fashion for improvement. Subjects and the treating physician completed a Global Aesthetic Improvement Scale (GAIS) before treatment and at each visit to subjectively evaluate treatment effect. GAIS scores demonstrated improvement as evaluated by both the subjects and the treating physician. Side effects averaged trace-to-mild erythema, edema, and pinpoint bleeding. This study showed that the 2910 nm erbium-doped fluoride glass fiber laser is safe and effective for improving the appearance of acne scars.
