I got Botox on my forehead at the factory.
I asked for it to be placed as high as possible on the top of the forehead because I was worried that it would change my impression too much (reviews saying it looked like Angry Birds, etc.). They placed it on the top, but it
wasn't very effective.
The muscles were paralyzed only at the top, and the middle of the forehead became more wrinkled, which made it look more wrinkled. It got deeper...
If you're going to get hit, I think it's best not to hit too much above your forehead!
