I did a lot of research on red light therapy, as it concerns its benefits, and one thing that kept popping up is to make sure your product is a medical grade product. Meaning, it did not come from overseas but from a reputable manufacturer. I chose a product called MyChondria. Just about every product on Amazon was an over seas product and definitely not medical grade. NO i am not being paid by MyChondria for any of these statements. My experience with using the product every day for 15 minutes with 1 minute per 30 degree positions in full body exposure are the following. The benefits i have felt are skin elasticity tightened, joint warmth relief, sinus cavity swelling significantly reduced, stretching improved and many others. They claim that this treatment helps grow hair but i am not that sure about that. Any way, the most important thing i can say about anyone that want to pursue redlight therapy, do your research and spend the extra $$ to get a medical grade product (one that you see the medical industry use at there offices where they use red light treatment)
