Rou, the Dr. I talked to didn't say anything about fillers for forehead, just botox. But maybe they do use it for the "elevens" between the eyes?
It's funny, my forehead lines don't bother me much because when I look in the mirror with a placid expression, they aren't there. (Also I wear bangs,LOL)
I'm sure they show up when I talk.
I'm trying the faux "frownies" at night with surgical tape between my eyes. I think Spider posted about that a while back.
