My grandmother swears by olive oil for keeping skin looking young, and also for treating facial cuts and scrapes (and for chapped lips). I've tried it, and she's right! I also use a little on the ends of my hair in winter to tame fly-aways.

My grandmother keeps a box of baking soda in her medicine cabinet, and she uses it as toothpaste to keep her teeth white and her breath fresh. It tastes terrible - truly, it's nasty - but wow does it work!

This one is so weird, but Gigi says it's true: if you rub a raw turnip or potato on your face every morning, and then again every night before bed, it'll clear up acne and remove spots. It's awkward, but it really does work!

My grandmother has always refused to drink from a straw. I thought it was just an odd preference, but nope - she says it's to keep wrinkles from forming around her mouth. Beauty experts agree with her, too, so from now on, no straws for me either!

Long before doctors discovered the havoc cigarettes wreak on our bodies, ladies knew it was bad for your beauty too. The smell? Disgusting! It also causes wrinkles and discolors your skin and teeth.

This is another one that just sounds so weird - sleeping on your back is better for your skin. Add to that the recommended 8 hours of beauty sleep, and you're gorgeous in the morning, darling!

My grandmother is 91 and she still rocks the red lippie. The key, she says, is choosing one in the hue that's right for you... and when you swipe it on, you'll always feel put together. She's right!

Gigi has always, always used Pond's Cold Cream every night to remove her makeup. I mean, there's a reason it's been around forever - it works!

Okay, so this might cause a few more wrinkles (Gigi calls them "laugh lines") but there's nothing you can wear that will make you look prettier than a smile. Thanks, Gigi!

So what words of beauty advice has your grandmother given you? Do they work? Do tell!
