Got a weird, obsessive beauty behavior you do in private? Here's mine: When I'm lying around reading or talking on the phone, I prop my legs vertically against a wall. I've done this since high school, when I heard it helps prevent blue leg veins (they run in the fam). But I've never known if the method was legit. Well, I asked Dr. Arielle Kauvar, a big-time NYC derm. Turns out that putting my legs up does approximately zero to prevent veinage. (However, she said wearing Spandex-y tights helps, as does calf-strengthening exercise.) Guess it's bye-bye to my weird beauty behavior. I need a new one! What's yours?
