Red light only helps if enough of it reaches your skin. The problem is, most masks never tell you how much light you are actually getting.
Bon Charge does. It lists its light strength, an irradiance of 40.8 mW/cm², with 240 LEDs spread across the mask for even coverage. So instead of judging a mask by how bright it looks, you can see the numbers for yourself.
