JAPAN -- Some young people are having injections of saline put into their foreheads to create a look they call bagel heading.
It's created by having a needle put into your forehead, then pressing in the center of the swollen area with your thumb.
People describe a stinging sensation as the saline begins filling the forehead during the 2 hour procedure.
The effect lasts 16 to 24 hours before the saline is absorbed by the body.
After that, the forehead reduces back to it's normal size.
