Tattoo laser good for acne scars: dermatologists

A laser used to remove unwanted tattoos appears to improve facial acne scarring, a small study shows.

Laser resurfacing has long been used in the treatment of acne scarring but this is the first time a picosecond pulse duration laser has been trialled for this purpose, according to a team of US dermatologists.

They claim this technology, normally used to remove red and green tattoos, delivers lower doses of energy than conventional laser resurfacing, theoretically leading to fewer adverse events.
