How to undo the brush on the face

[CheesyChester]

I wanted to make a little shadow on his face with a brush, but forgot to make a new layer. I cant undo it with Control + Z because i kept on working after i tried to brush, so it would undo everything else too. Is there anything like a History where i can manually remove this specific brush action?

Actually, you may be able to use the History Brush.
