WebJan 7, 2024 · During the laser hardening process, a well-defined laser beam is used to illuminate a localized piece of metal. The light from the laser is readily absorbed by the metal and this causes rapid heating to occur on the surface of the metal (in the localized area), but it does not penetrate below the surface layers of the metal. The main reasons ... WebThe use of lasers, IPLs and LED phototherapy for cosmetic purposes falls under the group of procedures known as light-based treatments. Light-based treatments using lasers and IPLs for non-surgical procedures rely on targeting specific chemicals in the skin, known as chromophores, to achieve the desired treatment outcome.
