Georgia May Jagger : I like Tracie Martyn face products; I prefer more minimal skincare. When I was younger—when you’re going through that period of trying everything to try to make your skin better and it actually makes it worse—I learned that the best thing you can do is steam your face and use a warm flannel [washcloth] when you’re in the bath. And I still love baths, with lots of salts in them. I love to watch a movie in the bath. I'll just put my computer on a chair—it’s a whole set up. I try not to get it wet.

For makeup, I have a much more glamorous approach, which I got from my mother. They say less is more, but sometimes I’m a bit more-is-more. And that came from my mom.

Jerry Hall : I like false eyelashes and red lipstick.

Georgia : I like minimal makeup, too, but I think red lipstick and big hair is a good way to go. In our family, that's always going to be there. [Laughs] I'm learning more and more how to do my own makeup—I pick up a lot on shoots. My mom’s incredible, though—she always does her own makeup. Back when she was modeling, they always used to have to do their own hair and makeup. That was part of the deal.

Jerry : I would try to copy what some of the good makeup artists had done on me in Paris. For example, I worked with Helmut Newton and he had this specific look he would go for, and he always used wonderful makeup artists and hair stylists. Now, I like black eyeliner and—

Georgia : Gold and bronze eye shadows, like the one I’m wearing now, RMS Solar Eye Shadow. Today, I tried to go very girly with some gold eye shadow, Rimmel Bronzer and some RMS Living Luminizer. I’m 21, so I’m still trying different stuff…

Jerry : She’s got safety pins in her ears!

Georgia : You won't let that go! But it’s gold! It’s a real earring. It’s not a real safety pin…although I did pierce my ear with a real safety pin when I was 14, but you didn’t see that at the time. It got horribly infected—my friend just sterilized the pin with a lighter.

Jerry : I change my eye shadow, but I never change my eyeliner. I use a wet powder from MAC, with a brush. I’ve been using it since it came out. And I recently started using the Rimmel red lipstick, which is very good. It’s very matte—I like a matte finish.

Georgia : I’ve seen people put powder over the top to make their lipstick more matte, but I haven’t experimented with that yet. I don’t do 'shiny' usually... I don’t like the feeling of lip gloss, but I like the way it looks.

Jerry : She has amazing lips.

Georgia : Actually, I have to exfoliate my lips before I put on red lipstick because otherwise it will get into the corners and stuff. I make my own scrub with lip balm and raw sugar.

Jerry : Good idea!

Georgia : That’s one of my homemade, natural beauty tips. I switch my lip balm around all the time—I’m always buying different organic ones at Whole Foods. I also really like Live Live in the East Village [in New York]—I’m really into all of their creams there, and they make a great deodorant.

Jerry : Oh, and they have this Bee Yummy Honey Mask—it’s a miracle. If you have any red spots or a rash, it makes them go away in a day.

My routine is easy: I use the Simple Cleansing Face Wipes and I wash my face with the Sisley Foaming Cleanser. And then I use a flannel, get it warm and steam it up, and try to clean my skin really good. Then I put on really expensive cream, like La Prairie. It just transforms your skin. I like expensive beauty products: Crème de la Mer, La Prairie Concentre, and the Skin Caviar cream. I definitely believe in using the spoon that comes with the cream, because you don’t get your germs inside the pot! It’s all scientific.

Georgia : I heard you’re also supposed to keep your cream in the fridge to keep it fresh.

Jerry : I never keep it ‘round long enough to do that.

Georgia : She doesn’t do plastic surgery or chemical peels or things like that, so she can splurge on expensive creams.

Jerry : I think those things ruin your skin and open it up and let microbes get in. [Aging] is great—you just don’t give a shit anymore; it’s nice. That’s a bonus.
