Ultraviolet light is for instance used for tanning, whilst infrared does not have any tanning power. Find out more about the differences between infrared and UV light.
Frequency and duration of use
UV light must be used in a controlled environment for a limited time. The Philips InfraCare can be used for longer periods of time and as many times as required for effective muscle relaxation and pain relief. However, if there is no improvement after 6-8 treatments, we advise you to consult a doctor.
