Kylie Jenner is the queen of full and pouty lips, so to begin your Kylie lip transformation, you should focus on making your lips look as plump as possible. To do this, you'll need some lip liner. It can be easy to overlook how useful liner can be to your look, especially if you're new to wearing makeup. But it should really be a staple of your routine. 

Charlotte Tilbury argues that liner is the key to accentuating the natural shape of your lips, meaning you can make them appear fuller and more defined with just a few strokes of your pencil. In an interview with Cosmopolitan, makeup artists and sisters SoniaXFyza, both of whom were professionally trained by Kim Kardashian's own makeup artist, revealed the secret lip liner that Jenner uses to get her perfect pout down. 

According to SoniaXFyza, the Kylie Cosmetics founder loves MAC Cosmetics' Lip Pencil in the shades Soar and Whirl. They shared, "Kylie uses either of these lip liners alone, going over her lip line and coloring in her whole lip."
