What Are Lasers and How Do They Work?

So what exactly is a laser? The word stands for light amplification by stimulated emission of radiation, according to NASA. As used in dermatology, a laser is “a skin-resurfacing modality that harnesses the power of light and heat to improve skin tone, texture, and coloration,” says Lara Devgan, MD, a plastic surgeon based in New York City. “It does that by creating a controlled injury in the tissue that stimulates the body to have a healing response that makes it look better.”
