We've found the exact lip liner that gives Eva Mendes her perfectly full and hydrated pout

If there's one thing we're consistently jealous of, it's Eva Mendes' beautiful full lips. Her secret? A hydrating lip liner from a stalwart beauty brand that just so happens to be on sale right now...

Although lipsticks will never fail, the best lip liners can make all the difference when it comes to a long-lasting and defined pout. With the right shade in your arsenal, you can look your best in one simple step.

We're always on the lookout for celeb-approved makeup products, and we just so happened to stumble across Eva Mendes' favoured lip liner and the secret to her always-glam appearance. It didn't take much to convince us to immediately add this to our basket...

We did some snooping to find out exactly which lip liner Eva's makeup artist, Genevieve Herr, is using. After some careful zooming and Googling, we discovered that it is the Bobbi Brown Lip Pencil, most likely in the cool-toned brown shade Rum Raisin. And the best part? It's 20% off at Bobbi Brown, Boots, and John Lewis at the moment.

Bobbi Brown Lip Liner

Genevieve Herr has been Eva's makeup artist for 25 years, and she's responsible for everything from the actor's stellar beauty looks on the cover of Vogue to her glam for the latest Stella McCartney campaign - so we more than trust her choice of lip liner.

The Bobbi Brown liner boasts a velvety smooth finish that glides onto the lips whilst adding definition, ensuring comfortable and long-lasting wear. There's nothing worse than drying lip products, especially during the colder months, but this product will layer beautifully with lipsticks or lip oils without any dehydrating effects.

If you've tried Sofia Vergara's trick for fuller looking lips, you'll know how powerful the right lip liner can be. Although Eva Mendes has lovely full lips without any makeup on, her pout is especially enviable after Genevieve has worked her magic. We're sold on the Bobbi Brown liner for hydrating definition.
