Margaret Qualley has revealed that the prosthetics she wore for the award-winning film The Substance left lasting damage on her skin.
The gory body horror film follows Elisabeth (Demi Moore), a fading movie star who is desperate to turn back the clock on her body. She injects herself with the mystery toxin to make herself look younger, but it comes with dark side effects, and she effectively births a youthful version of herself called Sue (Margaret Qualley).
