The A-list actress took to Instagram to share the after effects with a close-up selfie, displaying her freshly glowing complexion.
“After a long flight I do like to lie down and be covered in a mask of liquified [sic] cloned foreskins — frankly who doesn't?" Kate wrote in the now deleted post, most likely removed due to negative backlash.
"Thank you @georgialouisesk for an amazing facial. I especially liked you reassuring me it would be 'light on penis' as it was my first time." She added.
But Kate is not is not the only celebrity to dabble in such a facial with Cameron Diaz and Sandra Bullock also becoming fans.
Dubbed the ‘penis facial’ the EGF treatment uses liquefied cloned foreskins and was created by New York facialist Georgia Louise.
"I am always very mindful to explain radical serums and potions that I carry in my back bar," she revealed to People.
"So I always explain that EGF is derived from newborn-baby foreskin, from which cells were taken and then cloned in a laboratory."
But is the facial actually effective? According to experts yes. “There have been clinical studies that show EGF promotes wound healing, helps with brown spots, age spots, and texture," New York City-based dermatologist Debra Jaliman told INSIDER.
"Also helps in reducing wrinkles," she added.
