I am surprised that an extra amount of yellowness is perceived as being healthy or more attractive. Yellow can be sallow skin or jaundice. Western caucasian culture perceives a healthy golden tan to be desirable, but thius is rooted in socio-economic reasons rather than dietary. On the opposite side of the argument, the Indian nation now spends millions of dollars a year on skin lightening cosmetics as a paler skin is perceived to be a sign of wealth and higher caste. This mimics the earlier historical times in Europe when pale skin meant good breeding and wealth - it was the poorer folk that had to work on the fland every day gaining a ruddy, tanned complexion.
Despite all this, the stronger flag for desirability is symmetrical features and a smooth, even, unblemished skin, the sign of healthy youth. This can over-ride the overall level of skin pigmentation as a signal.

There's probably a lot you can tell from just the face. People with hyper or hypothyroidism have very distinctive looks (see google images.) Cranial nerve damage can result in altered expressions, like a crooked smile, drooping eye lid. Parkinsons gives a mask like appearence. I think some forms of hyperlidemia cause yellowish fatty deposits in the face.

The body images pandered to by the cosmetic industry are designed to bolster your self-image on a cultural and status score. They do not reflect scientific measurements of health.

Indeed; well said.
