LED stands for light-emitting diode. Different wavelengths of LED lights including blue, red, green and yellow, penetrate the skin at different depths. This penetration triggers biological processes that help the skin rejuvenate and heal.
Blue Light - reduces the activity in the sebaceous gland and kill a type of bacteria that contributes to acne by causing inflammation.
Red Light - improves scarring, signs of aging such as wrinkles and also reduces skin inflammation.
Yellow Light - stimulates the production of red blood cells, which play a vital role in skin healing and skin cell rejuvenation.
Green Light - is used to treat dilated capillaries, sagging skin around the eyes and under eye circles.
