If you find that your lips are thinning, turn to lip liner for help. Lip liner is the perfect makeup tool to hide fine lip lines and correct any imperfections that make your pout look smaller. You can plump up your lips or just ensure that your lipstick application will be perfect every time. Pro tip: choose a lip liner that has enough of a different color than your skin tone, but isn’t darker than your lipstick. This will make for the perfect tint for you.
