If you're spooked by the idea of acupuncture needles, harsh chemicals or cosmetics, or even surgery (hey, it's quite common now), but you still want to brighten your look, try a different kind of yoga.
Face yoga workouts are said to promote the production of collagen, stimulate the muscles, and reduce wrinkles. Each pose targets a specific area, such as "fish" for lips and cheeks, "bumblebee" for jaw, and "lion" for all the facial muscles.
Look for books, websites, and videos demonstrating the difference poses and put your best face forward! Your local natural health practitioner may even be able to teach it to you.
