I’ve been learning so much from your videos about the spectrum of solar radiation and how best to protect my skin. I would absolutely love it if you were able to go into a little more detail about LED light therapy, how it supposedly works, whether it is safe for the skin, whether there are many unknowns, and which types of machines or brands we can trust. I must admit, learning that visible light can cause some damage gave me cause for concern (I’ve been having LED light treatments for a few years) because it’s not clear to me how LED light is different to visible light (since I can see the light from LED lamps). (that might be a dumb assumption).

I found this article, but it’s not intelligible to a lay person like me:

Thanks for all your enlightening vids!! Keep up the good work!
