(Live Science) – A laser that is normally used in tattoo removal can also treat facial scarring from acne, according to a new study.
In the study, researchers tested the device, called a picosecond pulse duration laser, on 17 people who had facial acne scars. Researchers applied the laser to the patients’ faces a total of six times, with the sessions coming four to eight weeks apart. Each application took between 10 and 15 minutes.
“In general, even those who had deeper scars seemed to be pleased with the results,” said study author Dr. Jeremy A. Brauer, a dermatologist at the Laser & Skin Surgery Center of New York.
