I'm less convinced
about the skin absorption for good reason.
But as far as I know, research
about skin absorption rates of massage or coconut oils have not been done on adults (some on pre-term babies with very thin skin).

If you want to know something
about passive
absorption into the human
skin, this method is at least as good.
Combine that with the fact that many chemicals are absorbed through the
skin, and that higher temperatures and humidity may increase
absorption, 2 and you may think twice
about the chemical - laden products lining the perimeters of your tub or shower.
At much longer wavelengths, given the surface temperature (which won't change much by introducing a small amount of
absorption), the
skin temperature would only be a bit more than half of the surface temperature (example: for a surface temperature of 250 K and a small amount of atmospheric
absorption at 200 microns, the
skin temperature would be
about 56 % of the surface temperature), which could be less than the temperature even at TOA.
