LED Light Therapy
LED stands for light-emitting diode. These lights have been in use since the 1960s. 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 triggers biological processes that help the skin rejuvenate and heal.
Blue 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, improving acne symptoms.
Blue light also kills 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 does 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 aging. Red light also reduces skin inflammation.
Uses and benefits: acne, dermatitis, dull skin, eczema, psoriasis, rosacea, scarring, fine lines and wrinkles, age spots, and sun damage.
