Fat-melting Laser Can Zap Zits, University of Michigan Study

A laser designed to melt fat without burning surrounding tissue may be an effective tool for treating acne. The laser’s 1,708-nanometer, infrared beam takes advantage of a unique wavelength that fat can absorb more efficiently than water, which makes up more than half of the human body. It can penetrate skin with minimal harm on its way to reach and destroy deeper pockets of fat, says Mohammed Islam, professor of electrical engineering and internal medicine at the University of Michigan.
