What is the difference between red and near infrared light?

Red light wavelength 660nm is absorved at a higher proportion by the skin tissue, making it especially effective for boosting skin health and increasing collagen. Infrared light 850nm has a strong ability to penetrate deeper into the tissue, joints and organs, making it ideal for enhancing muscle recovery, reducing joint pain and inflammation.

Does light therapy have any side-effect?

In numerous clinical studies, red and near-infrared light have been proven as a safe, natural, non-invasive treatment. Patients using light therapy experience less pain, inflammation, risk or side-effects than are associated with many medical procedures such as medication and invasive procedures. However, it is very important to consult with your medical practitioner before stopping any prescribed treatment or procedures.

Should I wear eye protection during treatments?

Yes, eye protection is necessary. Medical grade protective goggles are supplied with your equipment. We recommend wearing your goggles throughout all treatments.

However, if you are using Red Light Therapy (RLT), you only need close your eyes and ensure you use the equipment at the distance recommended in your user manual (Red light only).

Is it OK to use light therapy if I have light sensitivity?
