I mistook her amount of makeup for post processing. It's clear that it's not as smooth as the skin on her face. Also, they're two different colors, irrelevant of their level of exposure. One is clearly tanner than the other.
I think the look of one being "tanner" than the other is due to exposure levels from the natural light source. Looking at the hands and face again, there are numerous tones (colors) - many of which match the tones of the face. Regardless, it's another great image from Daniel and I hope the discussion in no way takes away from that.
