Would someone kindly explain how this is possible?

excessively flexible skin is a known condition. You have seen the whole "attach as many pegs to your face as possible" world record?

your skin is really just an elastic band, some people have more elasticity than others.

you would also find that everyone loses the elasticity on the skin as you get older, as this causes the tough,leathery feel
