It's called the Kardashian effect.

When anyone of these reality star sisters endorses something, everyone is down to try it.

So of course we had to check out what is now publicly known as one of Kourtney Kardashian's personal beauty bag favorites.

The deos are available in these luxurious scents: Vanilla Grapefruit, Vanilla Summer, Fresh Vanilla Lemon, Pure Vanilla, Vanilla Lavender, and Vanilla Blackberry.

The multi-tasking formula uses a health-promoting beta-glucan technology packed with anti-oxidants, active botanicals and essential oils to not only fight odor, but condition, soothe and nourish the skin.

Check out the now Kardashian endorsed brand at Lavanila.com. And these deodorants aren't priced for the stars. These budget-friendly finds are available at $14, and a travel size for $8.
