1 Exfoliate damp lips with a toothbrush (regular or electric) for 30 seconds in a circular motion. This sloughs dead cells and stimulates circulation, so lips appear fuller.
2 Pat lips dry, and smooth on balm, then petroleum jelly. The double layer locks in moisture and plumpness. Leave it on like a mask for 10 minutes.
3 Blot your mouth with a tissue until lips feel hydrated, but no longer slick. Lip stains (the next step) stick best to a smooth, dry (unwet, not dehydrated) surface.
4 Outline your mouth with the tip of a lip-stain pen (they offer tonnes of pigment but won’t kiss off... great for date night). The closer you stay to the edge, the bigger lips will look.
5 Now tilt the pen, and fill the area inside the lip border with its chubbier side using long, even strokes. Once colour has dried, seal it with a hydrating balm.
