Eva Mendes has uncovered the fountain of youth–or at least the key to avoiding the onset of wrinkles.

The Cuban-American actress reportedly counts hanging upside down as her most coveted beauty secret. The 34-year-old believes letting blood rush to her head will slow down the signs of aging.

“Whether it is a photo session or a hot date, Eva swears by hanging her head down on a slant board for about 20 minutes. Allowing blood flow to your upper body and face will bring on a vibrant, flushed-with-youth look,” a tattle tells the National Enquirer.
