Now, when I say "lipstick," I'm talking about the whole spectrum of products that add some amount of color to your lips. I'm a big fan of lip gloss, which is what I wear most of the time. I like that it's easy to touch up without using a mirror. And I like the subtlety of it. I usually go with a more natural look, and full-on lipstick seems a little too made up for day time (for me, anyway).
My current favorite lip gloss is Clinique's chubby stick. Try to forget about the terrible, slightly profane name (what marketing genius thought of that one?). It looks like a big fat lip pencil (hence the name), but you don't have to sharpen it. When the tip gets low, you twist the bottom, kind of like a lip balm. This is a very important feature because (1) who carries a sharpener around in their purse? and (2) who wants to fool with a sharpener anyway?
The product itself is pretty awesome. It's not glossy (or gloppy or gooey), but it gives just a bit of shine and color. Just enough so you look put together without looking overdone. It's made with shea butter, so it feels very moist when you put it on, and it stays that way. Usually I wear it alone, but sometimes I put it on over lipstick. If my lips are feeling especially dry or chapped, I might put it on over Burt's lip balm.
When you see the colors, they might seem like a bit much, but they go on VERY sheer. That's make-up talk for "much lighter on your skin than in the tube." This is what hits my goal of just slightly turning up the volume on what I've got already.
You can try on a few shades to pick your favorite. Or, if you're ordering online, just pick one that has tones you like (pink or coral or rosy...). I like Graped-up. In spring, I'll probably switch shades. I like to wear bright pinks in warm weather.
I keep one in my purse and one in my makeup drawer. There's no excuse to go around without a little color, especially when it goes on easy and feels so good on my lips!
