Lip Illusion
Fuller lips in a blink of an eye.
First, apply your lipcolor - preferably a matte color, because this tric does not work as well with shiny lipstick or lipgloss.
Second, pick a highlighting powder (like a light powdered eyeshadow). Make sure the powder is a lighter color than your lipcolor! Apply the powder with your finger in the middle of your top and bottom lips.
