Almost all of the facial Botox before photos have subjects squinting and squishing their eyes and foreheads.And the after photos show that the subjects can no longer squint or squish their faces. Well, DUH.
We know that Botox will temporarily paralyze the muscles treated. It would be much more meaningful and relevant if photo subjects were using the same rested expressions in the before photo AND in the after photo. (And using the same make up or lotions.) Such comparisons would show whether or not the treatments were effective. Example: Are the browse lifted? Do crows lines look smoother?
