From facial and eyeball tattoos, to sub-dermal implants and multiple piercings, people are finding more outlandish ways to make their faces and bodies stand out.
But the people Katie meets go from one end of the spectrum to the other: some love their body work and others hate it. First up, Katie meets 33-year old butcher Jo who has a passion for prime cuts and is turning the knife on herself in an extreme and irreversible procedure known as scarification. Will Katie make her change her mind?
She'll also meet Chantelle, who shot to fame on Celebrity Big brother before getting 32FF implants. She's carved out a career based on her breasts, but as she opens up to Katie, she reveals she now regrets them.
