I'm curious about botox between the eyebrows!

I have a horizontal wrinkle between my eyebrows (between my eyes). It's gotten deeper lately and I'm worried about it. I heard that if you get botox between your eyebrows, you can end up with samurai eyebrows or smaller eyes, so I think I should also get botox on my forehead. But I'm in my 20s and don't have any wrinkles on my forehead, so I don't really want to do it. What should I do?
