The lasers used in Low Level Laser Therapy (LLLT) are typically small (often handheld) units, and unlike surgical and aesthetic lasers, do not heat the targeted tissue. Instead, LLLT emits low levels of light that are absorbed by your mitochondria which then can increase cellular energy production and help heal surrounding tissue. This process is comparable to plant photosynthesis, during which sunlight is absorbed by plants and converted to energy for the plants to grow. Low-level laser therapy may provide an effective alternative to surgery, or also speed up your healing from surgery. The treatment goals of laser can range from reducing inflammation and pain to regenerating tissue.
