Using dip down from Mac and using a duo brush from sephora it's an angled brush and a spooley. Apply the dip down with the angled brush and then fade out the brush with the spooley . Then clean up with concealer to get a clean finish :)
I start by underlining my brows with MAC Fluidline in Dipdown which is a gel liner, but you can use a brow pencil for this step too! Next I shade lower half with a medium brown brow powder then fill in the rest with a lighter brown shading.
