Don't konw that much but cranial deformations were common all over mesoamerica and the Andes. They were done partly for aesthetics and above all to visibly, physically separate the elite from the pleibans, a kind of introjection of power onto the body. The Maya case is perhaps the most famous, with elongated, flattened skulls and crossed eyes; only rulers had them, and the practice had to start at birth, by tightening a board onto the forehead and leaving a hanging ball in between the eyes during the beggining of infancy, while the skull was still soft. thus the elites were marked as visibly, physically different from the commoners. The practice dates back to the early pre-classic, the first signs of skull alteration are visible in Tlatilco in the Basin of Mexico... In the Andes there were similair practices but I don't know that much about them...

Labray piercings/expansions were also common to mesoamerican elites, particularly religious officials; during the late post-classic they were also used to mark the nobles that had made the pilgrimage to Cholula....

In mexica society prostitutes had to stain their teeth red, but I'm not sure how they did it. They were also the only women who could wear their hair down...
