Will Botox for Migraines Provide Cosmetics Benefit As Well As Possible Migraines Relief?

I just got my Botox for migraines yesterday by my neurologist. I know it takes a week to see full effects and I praying for less migraines. But I am a bit curious given the injection site for medicinal botox, will I see any cosmetic changes/improvements? I am young with only noticeable lines when I contract my facial muscles. I know I am being greedy hoping for less migraines and cosmetics improvements but I figured it was worth asking.
