Tissue fillers would not work well in those locations

I would not recommend using tissue fillers for forehead lines.  These lines are created because of repeated movement (raising your eyebrows).  The treatment here is with Botox, to limit that movememt. Depending on how deep the lines are while at rest, will determine how much the lines will soften after Botox treatment. 

Forehead lines are not due to loss of volume and will not look good if treated with filler.  As for the line across the bridge of your nose.  This is a result of either long-term furrowing / kneading your eyebrows together or from rubbing / pushing up on your nose if you are an allergy sufferer.  Here, I would use Botox for the glabella complex and then maybe add a little filler after the effect of the Botox has set in.
