London, UK - An elementary school teacher in the UK and France has embarked on a radical body modification transformation that's seen him chop off his nipples and tattoo his eyeballs.

Despite working in classrooms across the UK and France, Sylvain Helaine decided at the age of 27 to go through a radical body modification and tattoo transformation.

Since then, he has covered the vast majority of his skin in radical inkings. These tattoos include a unique combination of delicate black line work and colorful, intricate designs.

Now 40 years old, he is widely considered the world's most tattooed school teacher, a position that doesn't come without its challenges.

In a recent television appearance on ITV's This Morning, Helaine opened up about some of the more extreme modifications he's undergone – including tattooed eyeballs and chopped-off nipples – and what it's like to be so heavily tattooed.

"If I do something good, people will say, 'Oh, obviously he's the best, we were about to see that,'" Helaine said when asked about the experience of working as a teacher with so many tattoos.

"But if I do something a little bad, they will think that I'm awful because of my appearance."

"It always takes two minutes for children to accept me, two hours for the parents, and two days for grandparents. So it just takes a little bit of time," he explained.

"I love evolving. I love seeing myself evolving. You suffer, and I really hate the pain and am counting the days to the next tattoo session. I'm really anxious. I don't want to go, but at the end of the tattoo session, I'm really proud, and I feel invincible."
