Zoe Kravitz thinks having Botox injections to stop sweating is "dumb".
The 'Big Little Lies' actress hit out at the trend for the procedure, insisting it is a "scary" concept and urged her fans not to try it because they need to perspire.
Asked what beauty trends shock her, she told America's Vogue magazine: "Botox for sweat. That is the dumbest, scariest thing I've ever heard. Don't do that--sweating is key."
Although the 30-year-old actress didn't single out anyone in particular with her comments, Chrissy Teigen recently admitted she'd had the injection to stop herself sweating.
She wrote over a clip of her being injected: "@drjasondiamond is my favorite human. "BOTOXED MY ARMPITS.
"TRULY BEST MOVE I HAVE EVER MADE.
"I can wear silk again without soaking woohoo! (sic)"
In the video, the 'Lip Sync Battle' star - who has Luna, three, and Miles, 14 months, with 'All of Me' hitmaker husband John Legend - shared how painless it was and breathed a sigh of relief as she admitted she was scared.
She said: "That really isn't anything.
"It looked very frightening."
And the doctor told her: "That's it."
Although it was her first time having Botox under arms, Chrissy previously revealed she had her armpit "sucked out" to make her "feel better in dresses".
She shared: "I had an armpit sucked out, which was one of the best things.
"It's a big secret, but I don't care.
"It was nine years ago or so.
"And I had two inches to my armpit. Now it's back though, so now I've gotta pay for [liposuction] again."
However, Chrissy admitted that it was "the dumbest" thing she's ever done.
She continued: "It was so easy. It made me feel better in dresses; I felt more confident. It was the dumbest, stupidest thing I've ever done. The dumbest, but I like it, whatever. I have no regrets, honestly."
