I can advice You to try saturation intent mapping in device link profile for 
each image:

tiffgamut -ia -pj -cpcd Camera.icc Photo.tif
collink -g Photo.gam -is -cpcd -dpp Camera.icc Output.icc PhotoSat.icc
cctiff PhotoSat.icc -e Output.icc Photo.tif PhotoSat.tif

Camera.icc - normal camera profile without corrections,
Output.icc - Output device profile (pay attention to selection of the viewing 
Photo.tif - base photo,
PhotoSat.tif - more saturated photo, than perceptual intent.

In this case not only skin tones will be more saturated. Nevertheless the 
results are noteworthy. Saturation is image and device-depended.
For noisy images the downsampling of tiffgamut image may be necessary. In some 
cases the higher quality link (collink -qh) is required.

IMO, the correct ways are profile editing or classical manual color correction.
