To say the brow ridge is unimportant is absurd, it has a strong effect on how DOM you perceive someone to be (sluthate lingo for a moment), and generally comes hand in hand with big chins and jaws. It makes the entire eye area look more masculine.
Now you see my point. You're on a freaking jaw surgery forum, man
We're recessed as f**k with potato bone structures. Throwing a brow ridge on that will be idiosyncratic as f**k. Nevermind the original pictures show a brow ridge that looks more like a neanderthal shelf jutting out.
There's also a potentially huge point everyone is missing - forehead shape and angle. Just because there is a step-off between the brow ridge and forehead doesn't mean someone has or hasn't got a strong brow ridges. For example, plenty of men have more vertical foreheads yet simultaneously a decent brow ridge which gives them low eyebrows and nice eyes.
That is the part that is attractive and important! Heck, I looked at a picture and Brad Pitt probably falls directly into that category. Try morphing a brow ridge onto him and he looks utterly ridiculous without first making the forehead more slanted.
So now we get into the position of needing to shave down forehead bone in addition to brow ridge bone. I spoke to a number of surgeons about this very thing and it is possible to do, however, seriously, it's so f**king stupid and inconsequential I can't imagine a single person having the motivation to do it. Plus you'd weaken your forehead to an unknown degree.
