Amanda Seyfried reveals the one cosmetic procedure she won't give up after claiming she'll 'never' get work done

Amanda Seyfried has opened up about the one cosmetic procedure that she could not do without.

While she said that she has no plans to go under the knife for a cosmetic procedure any time soon, the celebrity has opened up about one procedure in particular.

Seyfried, who is set to star in The Housemaid alongside Sydney Sweeney, shared her thoughts on cosmetic procedures in an interview with Who What Wear.

The actor previously said that she had given up Botox and makeup while she took on the role of religious preacher Ann Lee, who founded the Christian sect The Shakers, in the recent film The Testament of Ann Lee.

The historical musical premiered at the Toronto Film Festival on September 9.

But while she described giving up makeup and Botox as having been 'worth it', Seyfried said that there was still one procedure that she will continue having.

She said: "I have a really good dermatologist who tells me that she's never gonna do anything but put Botox in the same place for the rest of my life."

But while she was filming, Seyfried said that she completely stopped having the procedure.

“I couldn’t get Botox for a year,” she said. “That was a big assignment... When I first got [Botox], I was, like, 'This is amazing,' because I frown a lot.

"But then it all came back in a way that was absolutely necessary for all the work I was doing."

Nonetheless, while she found it tough at times to forgo it, she was clear that it was worth it for the part.

"I'm an actor and that's my job and that's what I love to do," she said.

"I don't necessarily need all that in my life. I just like it. The things that I like, I can sacrifice a little. Of course I can."

Seyfried added: "We did make sacrifices, and it was worth it. Every day was fun. We didn't just survive, we thrived."

The actor has previously opened up about her skin care routine, including revealing that she sometimes struggles with eczema.

A video released with Vogue Beauty Secrets on March 18 saw her go through the 'unfiltered eczema routine'.

She drew praise online after doing the video, which was shared on TikTok and YouTube, without any makeup on her face.

Speaking in the video, she said: “You might be thinking: ‘What’s that on her face?’

"That’s my eczema, and I, too, suffer from perioral dermatitis."
