Don't know about red LEDs, but infra-red lamps are used for various
skin complaints.
I'm pretty sure they're used for their heating effect, rather than any
direct effect that the photons have.
Possibly. But UV defintiely used for sceriasis (sp ?).
UV high-power LEDs anybody ?

Not to dismiss all the doubts but red lasers have been used for
decades by physiotherapists to speed healing and reduce inflammation,
and also used from approximately the same time to heal diabetic ulcers.
I suspect they might be heat producing led's so the colour is incidental
no, there is no use of infra-red lasers, even though these were
originally cheaper and more widely available.

With lasers its particularly significant whether red corpuscles (or whatever
else you aim it at) absorb or pass the wavelength emitted.
