LED (light emitting diode) use during facial treatments is growing in popularity and this is no surprise considering the awesome benefits and few side effects and risks.
LED red light therapy gains the most attention probably because it stimulates collagen production! Red light penetrates 8-10 mm which is why it is able to effect the formation of cells and stimulate collagen production. It can decrease the appearance of fine lines and acne scars while increasing elasticty and smoothness.
Blue light penetrates 0.5 mm and acts more superficially. Blue light also has amazing skin enhancing benefits with its ability to kill acne bacteria, decrease oil production and tighten loose skin.
Between red and blue light is green light which penetrates to a moderate degree and has some properties of both while mainly being used to improve cell function and oxygenation.
You can purchase LED lights designed for at home skincare use. These are generally considered less effective but are used and loved by many! You should not use LED treatments if you are taking Accutane nor on broken skin.
