I've been looking into red light therapy and it seems to be a good addition to any skin care routine.
However, for it work efficiently wavelength is the key. I'm not sure exactly what's best, but from reading I've gotten the idea that I want a mask that works at at least 650nm. It's really difficult to find them though. I've found a few but they are all really pricy. Do you guys know of any good that isn't more than $250 or $300?
