Recently my colleague Marie Redding, About.com's Guide to Lingerie, wrote about a bra that's gaining traction (so to speak) in Europe. It promises to keep your breasts separated while you're lying in bed at night, to prevent vertical wrinkles in your décolletage in the morning.
Developed out of the Netherlands, the bra designers boast research from a Paris-based institute Centre d'Etudes et de Recherches Cosmétologique (CERCO), that shows chest wrinkles were less visible after wearing La Decollette just one night. I had a hard time locating the study - or the institute - but it may be that women are more concerned with supportive bras than supporting research. Reportedly, several thousand of the anti-wrinkle bras have been sold.
Another product promising to reduce chest wrinkles is called the Decollette Pad, a reusable silicone pad that adheres to your chest while you sleep. Who knows? I've heard of women who put strips of tape between their eyebrows during the night so their brows are less furrowed in the morning.
Here's Marie's blog, if you'd like more information. In the meantime, don't forget to wear sunscreen when you're outside, as UV rays are considered the primary source of skin aging, on your chest, and the rest of your body!
