In this tutorial, we learn how to apply sexy red lipstick. Start by applying dark red lip liner to the top lip, using an exact line where your lip goes. Next, draw the line on the bottom of your lip line up to where the crease of your lips meet. After this, smile while you paint on red lipstick with a makeup brush. Apply several coats and move the brush slowly so you don't mark your face. Apply the lipstick to both of your lips and make sure it blends in well with the lip liner you applied earlier. When finished, apply lip gloss if you prefer or just go out and enjoy the night!
