How to Darken Any Lip Color You Already Own — No New Purchases Required

This is one of the most old-school tactics in the book, but we’re still mentioning it because, well, it works like a charm. First, select a lip shade along with a liner that’s several shades darker. Hot tip: MAC ($18) has 40 colors to choose from.

Apply your shade, then line your lips not one but three times to make the color even darker. Next, add a few swipes of liner to the inside of your lip in the direction outward to meet the edge of your mouth. Use a small brush to blend the two colors into one darker shade.
