Cold laser therapy can be done by a physician or at home using a cold laser therapy device. The latter is a more convenient option since you can buy a cold laser therapy device. However, take care when self-performing cold laser therapy. It is advisable to consult a physician first before using the cold laser therapy device. Secondly, be sure to follow the guidelines outlined in the user manual. 

How does cold laser therapy work? 

During cold laser therapy, the device applies a low-level light to a targeted part of the body for about 5-20 minutes. This light could be a red light, modern infrared, or a balanced combination of the two.  

This light penetrates the skin (dermis and epidermis) and then cells absorb it leading to regeneration which stimulates healing, relieves pain, and promotes blood circulation. General healing requires a light wavelength between 600 nm and 700 nm. Deep tissues require up to 950 nm wavelength. Other conditions may require more or less light wavelength.   

How often can you do cold laser therapy?  

You can do cold laser therapy 1-2 times a week. Depending on the targeted area and the light frequency, cold therapy takes on average between 5-20 minutes. Consult with your physician to get an exact number. Some acute conditions may require therapy once or twice a day for a number of days.  

Cold laser therapy device buying Guide

What is the best cold therapy device that will meet your specific needs?  

To enjoy the benefits of cold laser therapy, it is essential to get the appropriate device that serves your needs. For this reason, some factors that you need to consider when you plan to buy the best cold laser therapy device for home use or professional use are:  

1. Laser power output

Higher laser power output effectively penetrates deeper underneath the skin and is a good choice for thicker joint and muscle tissues. Lower laser power output can be effective but only for areas that are less dense and those directly underneath the skin.

While more power can be effective for treatment, you should take caution when using laser therapy devices. This is because a high-power output can also damage an area of the body as well as the eyes.  

2. Laser therapy dosage  

Laser power output is different from laser wavelength. A laser device’s wavelength will determine which part of the body can be treated effectively. The standard laser therapy doses found in most cold laser therapy devices for home use are:  

  • 600 nm – 680 nm wavelength: For shallow penetration and good for skin conditions, bruises, and surface wounds.  
  • 800 nm – 860 nm wavelength: For deeper penetration and good for joint pains, inflammations, and deeper wounds.  

3. Treatment coverage area

Cold laser therapy devices are small or big depending on the surface area that they cover. For instance, smaller therapy devices may be good for stretch marks but not for muscle tissue or sore joints. A device you use on your back may be different from one that you want to use on your face or palms.  

In addition, devices that cover larger surface areas tend to be better as they generate more light power and hence perform better compared to their smaller counterparts. Smaller devices are great if you want a lightweight, portable device that you can carry around for on-the-go use.  

4. Quality

You can determine the quality of a device by checking its build and trying it out. Also, your physician can recommend a good brand for your consideration. Further, look out for certified or approved devices.  

You can check if the laser therapy device that you are planning to purchase has complied with safety standards for the build quality, power output, and light frequency.   

Finally, a good practice is to always check reviews and customer feedback on each device. However, be on the lookout for fake product reviews as they can be misleading.
