Cold laser therapy is low-intensity laser therapy that uses low levels of light to stimulate healing. Contrary to surgical or aesthetic lasers, it doesn’t cause your tissues to heat up. Sometimes cold laser therapy is called low-level laser therapy, low-power laser therapy or soft laser.

How Does Cold Laser Therapy Work?

Low-level light is applied directly to the problem area and the tissue then absorbs the light. This leads to a biological or chemical reaction of damaged cells that helps promote their regeneration. Different wavelengths and outputs are used depending on the purpose of treatment, typically between 600-700 nanometers, to treat superficial tissue. Patients will feel the device against their skin, but it doesn’t create any heat, sound or vibration. This laser is completely noninvasive and painless and usually only takes a few minutes.

What is Cold Laser Therapy Used For?

Minor Injuries and Sprains

Cold laser therapy is often used to treat minor injuries and sprains in physical therapy and sports medicine. Physicians use it to help reduce swelling and promote healing of joints and soft tissue.

Inflammation

Chiropractors, dentists and doctors use cold lasers to treat inflamed areas. Dentists will use it to treat inflamed mouth tissue and heal ulcerations, while doctors and chiropractors can use it to treat inflammation caused by arthritis, sciatica and chronic autoimmune diseases.

Aches and Pains

People who suffer from chronic pain can find relief with cold laser therapy. Therapeutic massage therapy is often also included with the laser.

Skin Rejuvenation

Dermatologists use cold laser therapy to rejuvenate skin. It can treat various problems like ulcers, burns, inflamed skin and rashes.

Wound Healing

Doctors are now using cold laser therapy to treat hard-to-heal wounds, including wounds related to diabetes.

In addition to these conditions, cold laser therapy can also help with burns, ligament injuries, muscle strain, hair growth, weight loss and nerve regeneration.

Acupuncture

Acupuncturists can use cold laser therapy for clients who are uncomfortable with needles. The low-level laser beams stimulate acupoints in the same way needles do, but don’t pierce the skin.

  • Safety
