Bagel head body art trend

A bizarre new trend in body art - known as the 'bagel head' - has emerged in Japan.

The look is created by injecting saline into the forehead until it swells up, and then pressing in the centre of the swollen area with a thumb.

The result gives the appearance that someone has a bagel stuck to their forehead, reports The Sun.

The process takes two hours to complete, but lasts just 16-24 hours, after which the saline is absorbed by the body and the forehead skinks to its normal size.

In a clip posted on YouTube, three people are seen undergoing the body modification in a Tokyo clinic.

It shows them having a large needle, attached to a saline drip, inserted into their foreheads.

As one customer's forehead starts swelling he says: "It's a relaxing sensation. It's kind of tingly and a building pressure that feels like it's sending me to sleep."

On seeing the final result, he smiles and says: "Oh sweet buttery bagels, I'm impressed. I look delicious."
