I spend so many hours thinking about this wrinkle or that spot on my face that I forget about my skin from the neck down. I'm determined to pay more attention to the rest of my skin -- especially my neck, chest, backs of hands and forearms, lower legs and feet. After all, it doesn't matter how young my face looks in 30 years, if I neglect these areas, they give away my age.

A simple routine -- body wash, scrub, moisturizer and sunscreen -- is all you really need. And these products are so much fun to use.

When I'm planning a trip, I think about the beauty advice I've heard from women who travel constantly for their jobs. Model Liu Wen advocates moisturizing mid-flight and wearing sunscreen. "Since you are flying at high altitudes, you might actually be more affected by ultraviolet rays," she says. (For more of Liu Wen's travel beauty tips, check out her interview at Estée Edit.)

I always pack face wipes and moisturizer in my carry-on. And instead of packing skin care before every trip, I have a mini-bag ready to go at all times. It contains some of my go-to products (sunscreen and an antioxidant serum, obviously) as well as lots of product samples of things I want to try. There's no better place to test new products than a great hotel bathroom.
