A laser developed at the University of Michigan is designed to melt fat without burning surrounding tissue. It could potentially be used to treat acne, researchers say.

It can penetrate skin with minimal harm on its way to reach and destroy deeper pockets of fat, said Mohammed Islam, a professor of electrical engineering and internal medicine. The research is described in a paper published in Lasers in Surgery and Medicine.
