Microdermal implants are a form of body modification which gives the aesthetic appearance of a transdermal implant, without the complications of the much more complicated surgery associated with transdermal implants.(information taken directly from Wikipedia)
Microdermal implants can be placed practically anywhere on the surface of the skin on the body, but are different from conventional piercings in that they are composed of two components: an anchor, which is implanted underneath the skin, with a step protruding from (or flush with) the surface of the surrounding skin, and the interchangeable jewellery, which is screwed into the threaded hole in the step of the anchor.
Body piercing consisting of inserting ornaments throughout the body is an ancient art form. In the Neolithic era in Africa, especially among the Mursi, a tribe of Ethiopia, labret stones were inserted in the lower lip or in ear lobes. Body modifications were practiced in ancient times, or at least traces found by archaeologists suggest that. Some discoveries have also been unveiled at an exhibition in the University of Pennsylvania Museum of Archaeology and Anthropology entitled "Bodies of Cultures. People around the world have been piercing, tattooing, and painting their bodies for ages."This exhibition showed among other things, a man with multiple piercings and earrings dating from 2900 BC.
In ancient Egypt, gold earrings were worn by men of high social status. In addition, members of the royal family frequently pierced their navel.
In the 1980s, piercing the ears of men had become more common in Western countries, although men have a habit of only piercing one ear.
Today, piercing is becoming more fashionable and is gradually spreading to all demographics of population.
