From the abstract, this sounds amazing. One dose, many light sessions. Much more targeted toxicity. I've received PUVA therapy to treat chronic Graft Versus Host Disease. https://en.wikipedia.org/wiki/PUVA_therapy https://en.wikipedia.org/wiki/PUVA_therapy The psoralen drugs kinda sucked. And I always developed an intolerance to the light. Skin would burn before receiving therapeutic amounts of light, so not worth doing. Much later, I had much better luck with UVB therapy. I have no idea why it worked better for me. I don't understand much about biology (square peg, round hole). But light therapy always seems like magic to me. Explanations for why and how it works is huge progress. There seems to be huge potential. I also anticipate using UV light for diagnosis. Last time I mentioned it (here on HN) I got some great links. But none of those advances have made it to my current care providers (SCCA, FHCRC). Soon.
