What is best: Red Light Therapy or sunlight?

Red Light Therapy provides an optimal amount of light of the right wavelength and, in contrast to sunlight, it won’t harm the skin because Red Light Therapy doesn’t emit UV rays. The sun, in a best-case scenario, can provide the same effect as weak Red Light panels. However, the panels
are usually much stronger, which is also a time saver. This is the amount of energy absorbed by the skin.

Light intensity in different situations:
Light intensity (mW/cm2)
Bedroom 0.01
Direct sunlight 5 – 20
Red Light Therapy 20 – 5000
