The 25-year-old "Clouds of Sils Maria" star says she does not want to change anything about herself, reported E! online.
"No, never. Never. I am so freaked out by the idea of doing anything. And maybe that's completely arrogant but I don't want to change anything about myself. I think the women who do are losing their minds. It's vandalism," Stewart said.
The actress said she loves mineral-based make-up products.
"I'm not great at applying make-up myself. My mom never taught me anything, she doesn't wear make-up... I like mineral make-up. You can't screw it up and it's not bad for your skin," she added.
