Martha Stewart loves this universally flattering lip liner — it sells every 10 seconds!

Martha Stewart has always been impeccable — but these days, she's known just as much for her flawless face as she is for her perfect place settings. Yep, the model-turned-mogul is hotter than ever at 81! And thanks to her trusted makeup artist of 10 years, Daisy Toye, we now know which actual cosmetics get the coveted Martha Stewart seal of approval. Chief among them is the iconic Lip Cheat Lip Liner by Charlotte Tilbury in Pillow Talk.

It's Martha's go-to lip liner, and she loves it so much that she uses it instead of lipstick because it's that good. Lip Cheat Lip Liner uses a special formula that makes your lips look fuller, and Pillow Talk is a universally flattering nude-pink neutral that works on almost all skin tones, all lip shapes and all ages. In fact, this Pillow Talk lip liner is so popular that one sells every 10 seconds throughout the world!

There's more to Lip Cheat Lip Liner than meets the eye, though. The plumper pout you get from this Charlotte Tilbury classic isn't just an illusion. The formula uses hyaluronic acid, a key skincare ingredient dermatologists love for its ability to draw in moisture. It also includes beeswax, an emollient cherished for its softening properties. And then there's hydrating jojoba seed oil. So this lip liner is like makeup and moisturizer in one!

If you want a look like Martha's, do what her makeup artist Toye most likely does: Outline your lips with Lip Cheat Lip Liner in Pillow Talk just outside the lip border, then fill them in with the liner and top with gloss. You can also use the liner in conjunction with your favorite lip color and enjoy the same fuller-lips effect.

Although we look to Martha for divine inspiration, she's far from Pillow Talk's only fan. There are all those real women across the globe snapping up six tubes a minute. But there are also other prominent women who swear by this one-shade-fits all color and this lip-plumping wonder formula. Best friends Michelle Williams and Busy Philipps have rocked this shade on the red carpet, and so has Salma Hayek.

The British makeup mogul Tilbury herself has said of Pillow Talk, “When you apply a flattering, nuanced nude shade, it's empowering and never overwhelming...the ultimate sultry, supermodel seduction.”
