Use the L'Oréal Paris Lip Liner Magique to line the lip contours, which helps prevent the lipstick from bleeding. The Lip Liner Magique is transparent, so can be used with any lipstick shade to prep the lips for colour. You can also use the product across the entire lip as a primer before applying your chosen shade.
Apply your desired red shade. Sweep the colour across your lips to build up intensity or dab the colour on with your index finger for a more subtle finish.
