The procedure involves mixing nightingale excrement with rice bran and water and applying as a face mask. The 49-year-old is said to be thrilled with the "fantastic" results that his complexion has started showing after trying it.
"Tom doesn't go in for Botox or surgery but he does pay close attention to all the new and popular natural treatments," a source told Now magazine, reports contactmusic.com.
"He recently started experimenting with the nightingale poo facial. It was recommended by a Hollywood pal and the results have been fantastic," the source added.
Cruise is said to be proud to have turned to the treatment - of which Victoria Beckham is rumoured to be a fan.
"Tom doesn't see splashing out on the facials as him being vain or weird - in fact, he points out there are much wackier fads out there. And he's proud of himself for avoiding the temptations of plastic surgery," the source said.
