So many grifters in this space. Someone I know desperately bought a $8000 red light therapy gun pitched to her by a chiropractor to help her father who had catastrophic brain damage from a stroke. :/ The gun has a dial on the side that lets you cycle through "Cancer", "Chronic pain", "Acute pain", and other ailments. https://neuro-solution.com/ https://neuro-solution.com/ Whatever legitimacy red light therapy has, it's set back by the legion of people trying to make money selling confusing products, and it's hard to tell what's legitimate or not. Between some red-colored LEDs glued inside an eye mask and those fan-cooled NIR array panels on aliexpress, what is legitimate and how do you tell? I think it's that confusion that seeds the field for people to say "none of it unless you're spending good money [on my product]."
