on this point curcumin aka tumeric has a quite a similar though not perfectly the same wavelength-adsorption profile (i.e. anything with a strong yellow color)
tumeric / curcumin is often used a magic skin treatment type dealie. question is why are not all these wanting-to-have-youthful-skin type people discovering transparency! answer is below but TLDR human skin is thicker and doses are still low.
some main points from the paper( damned paywell, see supplement)
> the dye only goes about 1mm deep, so maybe that works magic in a mice but not so good in humans nor noticable.
> the dye comes it at arnd 0.5-1 molar solution. gmw is 500 g/mol ish. so 1M solution is 500g in 1L or 0.5g in 1 mL aka 500 mg in 1 mL. Okay, fine, you prepare this and rub 500 mg on your big toe from a little 1 mL aliquot. the daily limit or whatever for the food dye is around 4 mg! Soooo...
>on the latter point, safety, the supplement had a bunch of stuff where they were like "we did all the normal blood tests on the mice, and looked at the tissue, and looked to see if they died later, and it all looks good"
