What is cold laser therapy

Cold laser therapy is a non-invasive and painless therapy that uses low-level light of varying wavelengths (red or near Infrared light) to combat various conditions.

Red light works at a wavelength of 650 nm and it is suitable for improving skin collagen production for a smooth and glowing skin tone and stimulating the rapid healing of wounds.

On the other hand, near-infrared light works at a wavelength of 850 nm which penetrates deeper into the muscle and joints, stimulating deep tissue healing and pain relief.

Does FDA Approve the Use of Cold Laser Therapy?

There are quite a lot of cold laser therapy devices up for sale in the market and a good number of them are certified by the food and drug administration (FDA) as safe for use at home, however, FDA does not guarantee that they work.

Since the safety of the therapy is guaranteed to a large extent, then you do not have too much to lose (well, except a few bucks) if you try.

  • The cold laser therapy device – There are different types of cold laser therapy devices with different specifications, this may determine their performance.
  • Consistency of Use – Cold laser therapy is not magic and it does not work once, it is a therapy that requires consistent use for a specific duration before its effect can be felt. If you do not use the therapy as you ought to, you would most likely see little or no result, and this does not mean that cold laser therapy is ineffective.
