Phototherapy uses a selective non-coherent light produced by LEDs. In more advanced systems, it uses plasma light more powerful than the previous types and light bands capable of interacting with pathological tissues on several levels.

In recent years, considerable research has been carried out on the action of specific types of light on skin rejuvenation, tissue biostimulation and the treatment of dermatological pathologies such as acne, pre-cancerous skin lesions and non-melanoma skin tumours. In addition, research into the use of phototherapy for treating muscle pain, neuralgia, myalgia, arthralgia and trophic disorders has also been carried out. There are no known side effects.

Photocatalysis light has the capacity to selectively destroy tissues (without damaging healthy surrounding cells) that have previously been treated with a photosensitising agent (ALA).

When used with infrareds, blue light has proved extremely effective in the treatment of moderate forms of acne and against skin aging, to accelerate the post-surgical healing of wounds, after peeling treatments and laser surgery and in the treatment of skin ulcers. This can even be done without an activator (ALA), exploiting the ability of infrared light to improve tissue metabolism and that of blue light to bind the bacteria that cause acne and are responsible for the inflammatory phases of the illness, reducing it considerably.
