Red Light Therapy?

I've been hearing a lot of about red light therapy using wavelengths between 600-900nm to stimulate collagen production. A quick scan of few articles suggest there is decent evidence (by dermatology standards) for the efficacy of this kind of treatment, but I'm wondering if that is the still the case for an at-home version vs. a med spa version. How strong would the light need to be to be effective, and is there any way to tell if a particular consumer product could deliver that?


  • Great questions! I haven't looked into this yet but if time permits at some point I'll see what I can find out. In the meantime, maybe other Forum members will share any info they have.
  • Also, let me know if you would like me to submit the question in audio for the show. I figured it was easier to put it here first, but I suspect it will be a fairly complex answer.
  • An audio question would be much appreciated! (But I can't promise when we'll get to it because we're kind of backed up right now.)
