What causes expression lines on your forehead?!
Question: A lot of expressions? lol
Answers: A lot of expressions? lol
Its almost impossible to avoid expression lines unless you have trained yourself not to immediately reflect emotions in your face. This is something common to a lot of asians and especially the chinese.
Either way, whether you always express joy or anger, you will have facial expressions lines. I tend to like my expression lines (surprised).
