How would I be able to slightly increase/raise my brow bone for a more distinct aesthetic brow bone and a more masculine look?

A filler like radiesse lasts roughly 1 yr and fills the brows out nicely for roughly $750/syringe and you probably need 2 syringes or 3 at the most.

This is not a commonly requested procedure, however, two options exist: Noninvasive filler placement: Radiesse would be your best option hear as it is calcium hydroxyapatite which is the filler which most resembles bone. It is a great way to start to make sure you like your results. The downside is that it is not permanent. Implant: There are a few different implants possible: PMMA, silicone, or medpor. This is a much more costly procedure and would involve a coronal incision (at the crown of your head in the hair) to avoid visible scars. The cost would be in the $7500 range. I would recommend the non-invasive option first before you undergo a major surgery.

The simplest way, especially if u are somewhat uncertain, is to use fillers like the HA's or fat. My preferred permanent way of augmenting the brow is to use methyl methacrylate placed through a coronal incision under sedation.
