From Kim Kardashian having her own blood injected into her face, to Snooki using kitty litter to exfoliate, celebrities have been known to go searching beyond “typical” beauty products to find the next best thing. And we can now add another beauty hack to the ever-growing list thanks to this Aussie actress.
