Low Level Laser Therapy Devices

Low Level Laser Therapy Devices

Low-Level Laser Therapy is the use of a red beam or near infrared beam to treat various health conditions. These devices have a strength of 5 to 500 milliwatts delivered by wavelengths between 600 to 1000 nanometers. The wavelengths chosen for devices depends on the specific purpose. Depending on the wavelength, body tissues absorb energy and produce heat. Small amounts of energy are transferred into the skin. This therapy is used as complementary or alternative treatment. When done by a medical professional or a qualified practitioner, it is considered safe.

Another form of low-level laser therapy called Cold Therapy combines two wavelengths and is applied at traditional Chinese acupuncture sites and there are no needles used. The low-level light is used to promote healing. This type does not cause tissues to heat up. It is also known as “soft laser.”

How Does Low-Level Laser Therapy work?

A laser light beam is applied to problematic or injured sites. The body’s tissues absorb the energy generated followed by biological or chemical reactions. Damaged cells begin to heal and regenerate. There is no sound or vibration, takes only a few minutes, and is non-invasive and painless. Uses include minor injuries and sprains, inflammation (swelling), wound healing, joint disorders, aches and pains, and chronic pain. The home market for these devices promotes them for general aches and pains, weight loss, to stop smoking, grow hair, and to treat migraines, high blood pressure, and wrinkles. Benefits are that it is non-chemical, not invasive, there is no cutting or burning, and there are no known side effects.

New Applications

Researchers continue to explore potential uses to treat conditions like Alzheimer’s and Parkinson’s diseases, as well as the potential use with cases of Traumatic Brain Injury, degenerative nerve conditions, and spinal cord injuries. These applications are limitless and in most cases show promising results.


Devices available include professional tabletop models and hand-held units of various sizes and capabilities. These varieties are used by dentists, trained therapists, doctors, and other qualified practitioners. Home versions range from combs to masks, wristbands and helmets (to name a few). Effectiveness varies among the equipment available, as well as, cost ranges.

Low-Level Laser Therapy devices are in demand because they provide a safe alternative to conventional medical practices. As a non-chemical alternative, it has the potential to relieve pain in a variety of health scenarios and the need for chemical intervention. Being non-invasive there is an alternative to some surgical intervention to promote healing and reduce inflammation. Ongoing research has the potential to show effectiveness in the treatment of diseases, injuries, and chronic pain. The fact that there are no side effects compared to medications and surgery, with proper use, is a strong selling point for professionals and patients alike.
