Use a lip liner that is the same shade as your lips. Fill in your lips with the lip liner. The lip liner will act as a foundation for your lipstick, offering a lasting effect. Once you’ve applied the lip liner, go slightly beyond the sides of your cupid’s bow to accentuate it.
It’s important that you do not go more than just a couple of millimeters when contouring your lips. Overdoing it will look very obvious to anyone who is standing close to you. You can also go a little bit beyond the sides of your lips to create a larger effect. Apply a little bit of a lip gloss in the center of your lips to finish off the illusion.
