LED light therapy is a popular non-invasive skin treatment for acne, sun damage, wounds, and other skin problems. People can choose to have LED facial treatment at a dermatologist’s office or at home by professional beauty services providers.
The treatment uses varying wavelengths of light to trigger the skin’s natural healing processes to repair skin. Several treatments are necessary to see results.
What is LED Facial treatment?
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.
Different wavelengths of light in LED lights, including blue and red, penetrate the skin at different depths. This penetration may trigger biological processes that help the skin rejuvenate and heal.
Blue light
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. Animal research indicates that blue light can improve the healing of third-degree burns.
Red light
Red LED light may improve scarring and signs of ageing, such as wrinkles. It may do this by acting on fibroblasts, which are skin cells that are responsible for collagen production.
Collagen is a protein in the skin and other connective tissues. It plays a role in skin healing. The body produces less collagen as a person ages, which causes the skin to show signs of ageing. Red light also reduces skin inflammation.
