Laser treatment is a subcategory of the therapeutic use of light. A laser is a device that amplifies and emits electromagnetic radiation, usually visible light. The light from a laser source is coherent (ordered) and monochromatic (only one colour). Lasers are used medically in surgery, similar to a knife that cuts or coagulates and removes. Here, the energy is relatively strong and is measured in watts. Soft laser treatment (also called cold laser and low energy laser treatment, abbreviated LLLT) uses the healing properties of different types of laser light on a variety of ailments and diseases to promote beauty or health. Here the energy is much weaker and is measured in milliwatts (mW). Different diseases and ailments react to different wavelengths. Myklasers are used, for example, for pain, inflammation, knee joint and hearing problems, allergies, respiratory problems, skin disorders, muscle, neck, shoulder and back problems, rheumatism, sports injuries, overtraining, wounds that will not heal, facial paralysis, broken bones, brittle bones and carpal tunnel syndrome. 

Low level laser therapy in general
The lasers used in LLLT are usually small (often handheld) devices, and unlike surgical and aesthetic lasers, you do not need to heat the targeted tissue. Instead, LLLT emits low levels of light that are absorbed by your mitochondria (the energy-producing organelles in many of your cells), which can then increase cellular energy production and ultimately help heal surrounding tissues. Low-level laser therapy can sometimes provide an effective alternative to surgery or medication - without associated side effects. It can help regenerate tissue, reduce inflammation, reduce pain and boost immunity, and research has shown its effectiveness in treating many conditions, including:

• Plantar fasciitis
• Rheumatoid arthritis
• Temporomandibular joint disease
• Exercise-induced muscle fatigue and injury prevention
• Skin conditions
• Traumatic brain injury
• Stroke
