Sure, concealer can hide a bad hangover and contouring creams give you cheekbones where you didn't have them before — but when we're talking about true transformation, eyeliner is where it's at.

That's why we rounded up our favourite ones and sorted them by type. Whether you're looking for a gel, liquid, pencil, or bright hue, there's something in this roundup for everyone.
