What they are
Infrared and Near-infrared light are light wavelengths commonly used in dermatology.
Infrared (IR) light therapy incorporates wavelengths of light beyond the visible spectrum to reach deeper layers of the skin. Unlike ultraviolet radiation, IR light does not cause DNA damage or sunburn. Instead, it supports cellular energy, repair and regeneration. Near-infrared (NIR) light, a specific part of this spectrum between about 700 and 1400 nanometres, penetrates even deeper into tissues. While far-infrared mainly produces heat, NIR stimulates biological repair, collagen production and healing without damaging the skin’s surface.
How They Work in Skin and Body Treatments
Infrared and Near-infrared light are absorbed by the mitochondria, the “powerhouses” within cells, triggering photobiomodulation, a process that boosts energy production and enhances cell function. The result is better circulation, faster healing and stronger collagen and elastin networks.
In dermatology, these effects help reduce inflammation, improve elasticity and speed recovery after procedures such as microneedling and laser treatments. IR and NIR are also used to calm redness, strengthen the skin barrier and improve tone and texture over time.
Beyond the face, IR and NIR light are increasingly used in body care to relieve muscle tension, promote lymphatic flow and support tissue repair. Regular treatments, whether in-clinic or with at-home LED devices, can help maintain healthier, firmer and more radiant skin by enhancing its natural regenerative processes.
