Stars' Surprising Beauty Secrets

If weren’t an actress, we bet she’d be a makeup artist, because she shared one of the coolest eyeliner techniques we’ve heard in a long time: “Put liner underneath the upper lid,” she advises. “It makes your eyes pop even more.” P.S. We tried it and she’s right.

may have little in common with her Glee character, but we suspect Rachel Berry would approve of the star’s obsessively thorough PM beauty routine, which includes a nightly face and hair mask. “I don’t care what I look like when I go to bed,” Lea admits. “I care about what I look like when I wake up in the morning.” Good point.

“I hold on to my mascara for a long time,” recently revealed to PEOPLE. “I actually prefer old mascara. It makes your lashes thicker and longer.” So that’s how she’s able to save enough money to afford all of those designer duds and luxe vacations.

What’s the one thing can’t live without? Well, besides the . Sunscreen! She calls it her beauty must-have and says, “My makeup artist that I ve worked with since I was 13 has been on me about it forever.”

What costs nothing and takes two seconds? hairstyling routine. “I put my hair behind my ears and I let it dry like that, so when I take it out it has a little bit of a wave.” Which leaves her with plenty of time for her busy schedule of being a mom, designer, TV host, model and producer.

Think eye makeup is the only way to make your eyes stand out? Well, Paula Patton is about to school you. “A little color on my cheeks – it makes such a big difference on your face, and lets your eyes come through.” So, if you’re not a blush or cheek stain girl, she highly recommends converting.

Not sure if you should hold on to an old lipstick or toss it? Do as does and sniff the tube. “You can usually tell oddly by the smell that it s time to throw them out.”

You don’t have to save false lashes for a night out, according to , who sports them practically 24/7. “Not all of us are blessed with really super-long and full, natural lashes, so false lashes can be our secret weapon to get a fresh new look.” Our recommendation: Use a few individual clusters on the outer corners for the most natural effect.
