LED light therapy is a popular non-invasive skin treatment for acne, sun damage, wounds, and other skin problems. The treatment uses varying wavelengths of light to trigger the skin’s natural healing processes to repair the skin. Several treatments are necessary to see results.
LED stands for light-emitting diode. These lights have been in use since the 1960s, but people have only recently begun to use them as a skin treatment. NASA originally developed LED lights for plant growth experiments in space. However, since then, LEDs have shown promising results in wound healing and human tissue growth.
Experts believe that blue LED light reduces activity in the sebaceous glands, which are small oil-producing glands in the skin. This reduction in activity causes the glands to produce less oil, possibly improving acne symptoms. Blue light may also kill a type of bacteria that contributes to acne by causing inflammation.
Red LED light may improve scarring and signs of aging, such as wrinkles. It may do this by acting on fibroblasts, which are skin cells that are responsible for collagen production. Red light also reduces skin inflammation.
