Clear skin and straight hair might make a woman more attractive in Japan, but in remote corners of the globe, women are judged by different criteria. On the National Geographic Channel's show Taboo, cameras document some of the world's most extreme beauty practices.
On the border of Burma and Thailand, members of the Kayan tribe begin their beauty rituals at a young age. At just 5 years old, girls start wearing brass rings around their necks, a ritual that's centuries old. As they grow older, more rings are added, and eventually, their necks start to look elongated, giving them a giraffe-like appearance. For these women, the shiny brass rings are the ultimate sign of female elegance and status. Some neck pieces can weigh up to 22 pounds.
"If I take the rings off now, I won't look nice anymore," one woman says. "They really are a part of my life."
