Can red light therapy really deliver a beauty and health glow-up? Here's the science

NPR sought the expertise of Praveen Arany for a report about the potential health benefits of red light therapy for health and beauty. Overall, when it comes to the health benefits of red light therapy, “in some areas we have reached the highest level of evidence. In the other areas, it remains more anecdotal,” with promising evidence but more rigorous science needed, says Arany, who has worked with several companies in evaluating their red light therapy devices. But he cautions that “just shining light on you is not going to make you superhuman in any way.” You still have to do all the other things conducive to good health — like eating right, exercising and getting enough sleep.
