Writing on her Twitter page, the actress explained that she had watched the show while on holiday in Jamaica.
"We watched the American Skins," she said. "Na mate! Brits did it better."
Scodelario, who admitted that she "quite liked" the US remake of Shameless, also retweeted comments expressing surprise that Skins has been so controversial in the US.
According to Perez Hilton, Scodelario also complained that the swearing in the show had been bleeped out and added that she is unimpressed that her character Effy is now blonde.
That message has now been removed from her Twitter page, but Scodelario later wrote: "Glad Perez Hilton is on the same page as me on the whole Skins USA censorship thing."
Skins airs on Mondays at 10/9c on MTV.
