If you're looking for a lip liner that really packs a punch, look no further than the Pat McGrath PermaGel Ultra Lip Pencil (£26). This is the most full-coverage lip pencil I have ever come across, and it's extremely pigmented, so you don't have to do too many layers to achieve a flawless finish. Its tip is very precise, and it's just creamy enough to ensure it doesn't skip and leave gaps when carefully working around your lips. What's more, it's transfer and feather resistant.
