Botox

Your experience please.
I am 63 and had Botox for the first and only time about 6 months ago. Only had it in my forehead.
It certainly ironed out some of the creases but the wrinkles just seem to migrate down from my forehead to the area under my eyebrows!
I haven't had it since for this reason though a friend said maybe if I had the Botox higher up, i.e. Nearer my scalp this wouldn't happen....
Can any one please give me the benefit of their experience.
Thank you
