What are these lines on the forehead?

I found this picture somewhere, but basically I have the same thing. It's not related to aging or sun. I don't go out much and always use sunscreen. What causes lines are these?

People use their eyebrows a lot for different facial expressions, and when you raise your eyebrows, it kind of scrunches up the skin on your forehead. After years and years of making different faces, it's not uncommon to have a few lines up there.

Yeah, everybody has them...unless you've been botoxed or airbrushed.

I have three huge ones in my forehead, like dents. I always raise my eyebrows lol

I've got them too! Like Cest said before, people who use their eyebrows a lot for facial expressions (like me ) tend to have these kinds of lines.
