Zoe Kravitz thinks having Botox injections to stop sweating is "dumb"

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."
