Girls I need serious help to fill in my eyebrows. Prom is coming up soon and I want to look poppin' 😂 any good tips on filling them in? I don't want to go all out and bold but have a natural look. (My eyebrows are really sparse so I'm stumped on how to fill them in properly) 
 Should I get NYX brow pencil, Anastasia Beverley Brow Wiz or any other brand? It's my first time filling them in btw
Excuse all the acne and oily skin, I've had a random breakout.
