Celebrity make-up artist on Charlotte Tilbury's talented team, Kate Synnott, advices, "Put eye cream on your lips to hydrate them, because you've got thinner skin around the lip area." She further explains, "The cream is more delicate. Whatever is good for the eyes is good for around the mouth and just on top of the lips to hydrate."

The trick is to leave it on like a mask, overnight if you can, and follow up with any lip balm on top. You will wake up to a surprisingly soft pout. This beauty secret is one that Synnott uses on her celebrity clients and brides as well. "It's actually really great one to use before lipstick because it absorbs in," she says. "If you put lip balm on before lipstick, then it's quite slide-y. It stops that from happening." For ultimate lip hydration, opt for products that contain hyaluronic acid, as it floods the skin with moisture so it can hold up to 1,000 times what the skin already has. And it draws all of the moisture to the surface of the skin."
