The one where Jennifer Aniston unexpectedly slathered fish semen on her face.
"First of all, I said, 'Are you serious?'" the 54-year-old recalled. "'How do you get salmon's sperm?'"
Ultimately, she gave the unique treatment go. And while the Cake actress admitted she's not entirely sure she noticed a difference in her skin, research reported by the National Library of Medicine has shown that the spermatic fluid from salmon restores skin elasticity, repairs moisture barriers and helps minimize inflammation. The treatment, a K-beauty staple that has slowly made its way to the U.S. for topical use, is most beneficial for those with dry, damaged and dehydrated skin.
Although Jen hasn't been convinced of salmon sperm facials, she does swear by peptide injections—a treatment that helps increase cell turnover and collagen and elastin production—saying, "I do think that's the future."
But before you comment on The Morning Show star's looks, no matter what beauty procedures she's turned to, we'll stop you right there.
As she explained, "That's a habit of society that we have these markers like, 'Well, you're at that stage, so for your age.' I don't even understand what it means."
According to Jennifer, she feels better from the inside out than ever before.
"I'm in better shape than I was in my 20s," she said. "I feel better in my mind, body and spirit. It's all 100 percent better."
Of course, the Murder Mystery star isn't the only A-lister to open up about the cosmetic treatments she's received over the years. Keep reading to see what other procedures celebs have dabbled with.
