In short, rather a lot of difference! I'm sure you've heard it a thousand times before but eyebrows really do frame the face. When they're filled in, eyebrows make everything else look a little bit neater (but not the mascara smudges, oops) and just finish off a look.
Here I used a light application of Anastasia Beverly Hills Dipbrow Pomade in Medium Brown. It is a gel product which lets you fill in brows lightly or fully, you can even mimic individual hairs with it if your brows are sparse.
This is a very speedy application as it was a work day and I was in a rush as per usual. It took less than a minute to do each brow but made a lot of difference, to my eye look and as you'll see below, my whole face.
