The 22-year-old, from Colombia, says he has always loved skulls ever since he was a child, but only started modifying his face after his mother died because she didn’t approve of it.
One of the first procedures Kalaca had was to remove the lower half of his nose and cut off his ear lobes.
He then had his tongue split in half and tattooed it to a blue-grey colour before tattooing large black eye-sockets around his eyes.
Large teeth and hollow space was shaded in ink around his mouth and his hair was shaved into a mow-hawk style to show off his head tattoos.
He told Rio Noticias website:
“Body modifications are a personal decision and should not be judged.”
