Perfect eyebrows everytime when applying eye shadow and/or eye pencil
I usually go to a Benefit Brow Bar near me every couple of months when I forget to pluck my eyebrows and keep the arch nice and neat. It also helps sometimes to go to one just for some instructions on what to do too and see what they're doing and what they recommend.
A good product I use for highlighting and adding the illusion of eyebrows to mine is Clinique's Instant Lift for Brows. The crayon that is for the brows (about the same size as one of the smudge sticks that have been coming out recently) can be used on it's side to create precise lines for brows or used fully to create the illusion of depth, with the highlighter under your brows, etc. Another good one they make is the Superfine Liner for Brows, as well as Dior's Universal Brow Liner. I recommend you check some of these out.
I hope this helps you.
