Can a frozen effect from Botox be fixed?

I am 30 and got Botox, mostly as a preventative measure but also to address some fine lines on my forehead, three days ago. I was concerned about looking frozen and so I asked to go very conservative. I ended up getting 26 units total for my forehead, glabella, and eyes. One day later, I could hardly raise my eyebrows and when I do, they peak on the edges. My forehead barely moves and has an uneven appearance. Will this improve over time? Can it be corrected? I don't know whether to wait or try to get it corrected.
