Cold Laser FAQ
What is the difference between cold laser therapy and red light therapy?
Cold laser therapy and red light therapy are similarly the same thing, they are both considered low level light therapies (LLLT) and both utilize a red light. The long wavelengths stimulate pigment molecules in the mitochondria of skin cells to produce chemicals the body needs for healing and repair, which is why you may see red light therapy being used by medical aestheticians to treat skin appearance such as acne, wrinkles, and scarring.
Is low level laser therapy (LLLT) the same as cold laser?
Low level laser therapy is a broad term used to categorize lasers that have a low level of lightwaves emitting from them (ex: cold laser therapy, red light therapy).
Can cold lasers damage the eyes?
In the case that there is even a remote chance of a light beam reflecting or directly hitting your eye, laser safety glasses need to be worn as a safety precaution due to the intense beams of light laser machines give off. Permanent eye damage can happen if not wearing the proper safety glasses.
How often can you do cold laser?
Cold laser therapy has a cumulative effect, therefore it is generally best to receive laser twice a week for the duration of your treatment.
Does cold laser penetrate bone?
Bones, along with muscle and other soft tissues, are transparent to certain laser lights which means the laser light can safely penetrate it. Depending on the dosage and the output power of the laser machine, low level light therapy can stimulate cellular metabolism, as well as increase the synthesis of proteins. All of these changes contribute to bone regeneration.
Does Cold Laser Therapy Work?
Continuing research on cold laser and red therapy is showing promising results. https://pubmed.ncbi.nlm.nih.gov/28987080/ this review of literature on low level laser therapy concludes “Many studies have demonstrated analgesic and anti-inflammatory effects provided by photobiomodulation in both experimental and clinical trials”.
