If you are wondering about the tattoos, they are real! Rick Genest (a.k.a. “Zombie Boy”) has eighty percent of his body covered, “[...] including intricate designs of an entire skeleton (skull included) and is thematically, the depiction of a body decomposing—complete with flesh eating insects. To date Genest has spent over $17,000.00 on tattooing his body and will continue until his tapestry is finished.” 
Dermablend commissioned Genest to do ad campaign for their body and leg cover makeup, and in the video you see “Zombie Boy” as he used to be with no tats. It is pretty impressive the transformation.
Notes about Genest (from bio published on his website):
Twenty-Six year old Rick Genest will challenge your sensibilities about what you believe to be beautiful. At his core he is a chiaroscuro of both light and dark—part gentle warrior, part anti-establishment artful dodger, and he has serendipitously become the ‘it’ muse for anyone who believes in a brave new world without judgment. His tattoos have equally intrigued and inspired a cult following—more than 30,000 followers on Twitter and 65 groups/ pages to him on Facebook. He has sparked a revolution with fans who see beyond the visceral and want to know everything they can about the mysterious performer, model and muse known as ‘Zombie Boy.’
