Hollywood star Margaret Qualley has revealed that the prosthetics she wore in the critically-acclaimed horror movie “The Substance” caused so much damage to her skin that it took about a year to recover.

The actress, who stars alongside Demi Moore in the body horror film, says it took "probably a year" for her skin to recover.

Margaret Qualley says her skin went through a lot while filming 'The Substance.' On Josh Horowitz’s 'Happy Sad Confused' podcast, the actress opened up about the effects of wearing prosthetics for the film and how it impacted her skin.

Margaret Qualley shares the challenges of The Substance, a role that pushed her limits and earned acclaim. These actors never use their real accent. For this list, we’ll be looking at, and listening to actors whose accent we hear most on screen isn’t the one they use in their real lives.

"It took me probably, like, a year to recover physically from all of it," she told a podcast about the prosthetics used in the film.

Qualley stars in the film opposite Demi Moore, who plays an aging film star Elisabeth Sparkle. Sparkle takes the "substance" in order to transform into Sue (Qualley) but there's a catch: the pair must switch back every seven days. If they don't, Sue will begin deteriorating (and, it turns out, so will Sparkle).

During a recent appearance on the Happy Sad Confused podcast, Margaret Qualley revealed that the prosthetics she wore in "The Substance" "f--ked up" her skin, saying that it took "a year" for her skin to fully recover from the acne.

During the ceremony, she presented an award with her Substance costar, Demi Moore. Qualley was also nominated for Best Supporting Female Actor, Film, for The Substance, but the trophy went to Zoë Saldaña for her role in Emilia Pérez. A winning night for women supporting women in Hollywood, indeed.

In 'The Substance,' Margaret Qualley wore a mountain of facial prosthetics, which had a detrimental effect on her face.
