Will filler in my brow bone for the space in my upper eye lid make my brow bone more pronounced?

Yes, filler and/or Botox can be used to lift the brows. It will take 1-2 weeks for final results. I recommend getting a formal evaluation with a cosmetic dermatologist. Best, Dr. Emer

You could have an injection placed above the brow.  A filler such as Voluma or Restylane could help lift the tail end of your brow and shouldn't cause heaviness.  The injection shouldn't be placed under your brow, therefore, you shouldn't lose "space" on your lid.  Properly placed filler will open your lid.  Another thing to consider is having your brows shaped.  I wish there was a full face picture of you, but from these pictures, your brows have a downward slant.  After a bit of filler, have a brow specialist shape your brows. Sometimes a simple thing like that can make a world of difference. Best of luck!

The injection should be placed in the space between the eye and the brow bone, in the recess where the volume loss is.  Only an experienced injector should attempt this, and it should be done using a microcannula.  The results are astounding when done properly!

Yes, hyaluronic acid based fillers like Restylane can be safely injected into the upper eyelid/eyebrows using a blunt tip microcannula. The filler should not make your bone look "heavy" if done appropriately. 

Thanks for your question.  Filler can be really useful to "fluff" or pad the area at the orbital rim.  This helps soften your look and make you look less gaunt/tired.  Usually in this area, where the skin is thin, the filler needs be placed deep so there are no ridges or bumps.  It is actually layered on the bone (not in it) and should not make the brow bone bigger or more pronounced.  We are trying to mimic the look of fatty tissue there so it will simply fill the gap and not shorten or minimize your lid.
I would use a light Hyaluronic acid filler such as versa or belotero for this purpose.  Juvederm, voluma etc will attract too much water and be too heavy for this area.
Hope this is helpful.  Best of luck to you,
