Cold Laser Therapy Devices For Pain Relief

Cold laser therapy is a low-intensity laser treatment that uses minimum thermal energy to heal wounds and injuries. Typically, the light penetrates as deep as 5 cm into your skin and gets absorbed by your cells, resulting in increased cellular metabolism, which helps speed up the recovery of damaged cells. It is called therapy because it does not use harsh levels of light like other forms of laser therapy.

It is on the milder side and created especially to reduce pain or eliminate swelling. Cold laser therapy is also known as low-level laser therapy (LLLT), low-power laser therapy (LPLT), soft laser biostimulation, or photobiomodulation.

How does cold laser therapy work?

During the procedure, low-level light is applied directly to the targeted area. This light is absorbed by the skin tissues, leading to a reaction that rejuvenates the damaged cells. The non-thermal photons of the light penetrate the dermis and epidermis to help increase the intracellular metabolism. This acts as a catalyst for faster healing.

Cold laser therapy uses specific light wavelengths to help boost the healing process. For general healing, a wavelength of 600 to 700 nm is used. For deeper tissues, a wavelength of 780 to 950 nm is used.
