How do lasers use infrared radiation
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. WebRed light is similar to infrared, but you can see it. Red light therapy is also called low-level laser therapy (LLLT), low-power laser therapy (LPLT), and photobiomodulation (PBM).
