Zoë Kravitz is the ultimate cool girl. When she's not busy playing Bonnie Carlson on Big Little Lies, she advocates for women's rights and turns heads in the most fashion-forward looks. Whether she's owning a blonde pixie cut or showing off one of her 55 dainty tattoos, there isn't anything Kravitz can't pull off. But there are certain beauty trends she'd prefer to avoid, regardless of how popular they might be in Hollywood.

In a recent interview with Vogue, Kravitz said she was shocked to hear that some celebs (ahem, Chrissy Teigen) use Botox to stop sweating."That is the dumbest, scariest thing I've ever heard," she told the magazine. "Don't do that—sweating is key," she added.

While Botox is known to temporarily reduce the appearance of frown lines, forehead wrinkles, and crow's feet, it's also FDA-approved for the treatment of hyperhidrosis, aka excessive sweating. For people who have this condition, Botox can indeed offer some benefits. (Related: 6 Weird Things You Didn't Know About Sweating)

"Hyperhidrosis can be debilitating from a psychosocial standpoint when the sweating is so severe that it can affect people's self-image and self-confidence," says Susan Massick, M.D., a dermatologist at The Ohio State University Wexner Medical Center. "Botox is just one of several different treatment options available for people who suffer from hyperhidrosis."

But what if you're hoping to reduce sweating for purely cosmetic reasons and don't suffer from hyperhidrosis? In those situations, it's important to weigh all your options with your derm first, says Dr. Massick. "See a board-certified dermatologist for evaluation and treatment because there may be other options to try before going to Botox injections," she explains.

If you do happen to get the all-clear, your doc will tell you how much Botox needs to be injected in affected areas, says Dr. Massick. "There is reliable data on how many units to inject at a certain time with maximum recommended dosages," she explains.

Still, Botox is only a temporary solution for sweating—excessive or otherwise—with effects lasting only three to six months, adds Dr. Massick. "When the sweating starts to come back, it's usually the indication to repeat the injections," she says.

Bottom line? Getting Botox injections to treat excessive sweating isn't "dumb" or "scary," as long as you're doing so with a trusted professional. But while the treatment is generally safe, it definitely isn't necessary for those who don't have some type of excessive sweating condition. Not to mention it can be quite expensive (up to $1000 per treatment) and isn't generally covered by insurance. So, to Kravitz's point, why put yourself through that when your $5 drugstore antiperspirant can basically get the job done?
