Helen Mirren's Ageless Secret: Eyebrow Tattoos

Dame Helen Mirren just dished on a BIG beauty secret she swears by: Getting her brows tattooed.

As the 72-year-old told the Daily Mail, she recently tried the microblading trend, which "she loved."

"I was fed up of my brows barely being there and when one of my girlfriends got it done, I thought that they looked great," she said. "They’re very lightly and delicately done—but it means that when I get up in the morning and I have no makeup on, at least I have eyebrows. It’s made a huge difference."
