Red light therapy is also known as photo biomodulation (PBM), low level light therapy (LLLT), bio stimulation, photonic stimulation or light box therapy.
Red light is used to treat the outermost layer of skin, with wavelengths range between 630-880nm, otherwise known as the epidermis, penetrating about 8-10 millimetres into the skin. It is thought that when this layer of skin absorbs infrared light, the fibroblast cells that are responsible for the production of collagen proteins are then stimulated. The increase in collagen production can make the skin look smoother, which can mitigate the appearance of fine lines and wrinkles.
Blue light, on the other hand, targets the oil glands located in the deeper layers of skin. By reducing the amount of oil that these glands produce, the skin can become drier which in turn could lead to fewer acne breakouts.
Blue LED light therapy can target those oil glands and make them less active. Blue light also kills the bacteria causing acne under the skin, which can help in treating serious acne problems, including cysts and nodules.
Blue light is also frequently used in combination with red LED light which helps with acne, heals scars and supports anti-inflammatory effects. According to some studies, blue LED therapy can enhance the healing of third-degree burns.
