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. Ongoing 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 light therapy 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.
Experts believe that Blue LED light therapy 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.
Animal research indicates that blue light can improve the healing of third degree burns.
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 aging.
Red LED light also reduces skin inflammation.
