First things first, pick your red.
Store assistants will know their products, and be able to recommend options to you, but the easiest way to see if a lipstick suits you is to hold it up against your skin, or just try it on.
Here, we can see that the first lipstick is too bright for Robyn's skin tone, but the second (Ruby Woo by MAC) is a perfect red.
Meanwhile, the first lipstick is too dark for Kim's skin tone, but the second (Lady Danger by MAC) has a nice pop against her skin.
Then assemble your tools.
Begin by filling in your lip line with the pencil. This will prevent the lipstick from bleeding.
Just follow the natural line of your lips. If you'd like to exaggerate certain features - like making a more defined Cupid's Bow - then you can do this now.
Next, fill in the rest of the lip with the liner.
Apply a layer of lipstick, adding a second layer if you'd like to intensify.
And enjoy your ruby lips!
