Julia Roberts received one of her best beauty tips ever from her grandfather.

“I brush [my teeth] with baking soda,” she tells InStyle in the magazine’s September issue. “[My grandfather] would put a big heaping mound of it on his toothbrush. He had only one cavity in his entire life.”

Because the actress is so loved for that big, sparkling smile, she’s sure to take care of it. “Sometimes that’s all I do as far as a regimen goes,” the busy mom says of tooth brushing. “Look, I’m happy if I have on moisturizer and ChapStick! When you’re dressing three people besides yourself, something has to fall away. I’ve learned to always have a big pair of dark sunglasses within arm’s reach before going out.”

When she does have time to primp, Roberts relies on a tip from the late makeup artist Kevyn Aucoin: “‘Mascara, mascara, mascara!’” she recalls, naming Lancôme’s Hypnose as a favorite. “It just makes you look like you’ve had a good nap.”

Would she ever rely on Botox or plastic surgery for the same effect? Probably not. “I’m pro whatever works for you,” she says of such procedures. “For me, at this point, I’m clinging to my good genes and lots of hugs and kisses from my husband.” Hear more from Roberts in the September issue of InStyle, on newsstands Friday. Tell us: What’s the best beauty secret you’ve ever received?
