There are two types of glands that produce this sweat: apocrine and eccrine—and only the former is responsible for that body odor. “Apocrine glands are found primarily in the underarms, around the genitals, and around the nipples,” Dr. Jaber tells SELF—essentially, areas with hair follicles. Sweat here contains proteins, fat, and other substances that, when broken down by bacteria, generate an odor, hence why Dr. Jaber says “whole body deodorants are best suited for those who sweat a lot in the groin or these particular areas.”
Eccrine glands, on the other hand, exist all over your body. They mostly secrete water and salt to cool you down, which explains why your back, arm, face, and chest may get sticky in the heat, sure, but they don’t actually stink (or require a tropical-scented fix).
Is whole body deodorant safe to use everywhere?
While these bathroom staples can help you cover BO in certain crevices, some experts worry that the “whole body” label might encourage folks to use them in places where they really shouldn’t—namely, in or around the genitals. Sure, all-over deodorants are marketed for external use, but some brands still reference “intimate areas” and portray actors shoving the stuff straight down their pants. So, it’s easy to see how people might get confused.
The thing is, your privates and these types of products typically don’t pair well together, the gynecologists we spoke with agree. “Nothing should be placed internally that isn’t meant or prescribed to be there, because this is a sensitive mucosal surface,” Dr. Lincoln tells SELF. That especially includes essential oils and “natural” fragrances in deodorants, which can be super irritating and throw off your pH balance, leading to infections or even more odor. For the same reasons, even using whole body deodorants near the genitals (say, on your inner thigh) can be risky. And sprays in particular might drift into sensitive parts of your vulva, like your labia minora, clitoris, and vaginal opening.
That’s not to say BO control is entirely off-limits below the belt, though—just be careful to stick to areas with hair follicles and choose the right product. “Creams and solid stick formulas are generally safer for the external genitalia, since they offer more controlled application,” Dr. Gaither tells SELF. It’s extra important to stick to fragrance-free formulas in these regions, too, both gynecologists say. “Because if the product does get near the vulva or into the vagina, the chance for bacterial disruption and chemical irritation is less than with a fragrance-containing one,” Dr. Lincoln explains.
As for vaginal “odor control”? It’s not only potentially unsafe—it’s unnecessary. Vaginas are self-cleaning, thank you very much. And as any medical professional will happily inform you, “it’s completely normal for your vagina to have a natural odor,” Dr. Gaither says. “A healthy one often has a mildly earthy, musky, or tangy scent due to the presence of beneficial bacteria that help maintain a healthy vaginal microbiome.” In other words, it’s unrealistic for your genitals to smell like an edible arrangement or a fresh bouquet, despite how often marketing suggests otherwise.
Now, if you’re concerned about the odor because it smells fishier or stronger than normal, or you’re experiencing symptoms like itching, burning, pain, or changes in discharge, the experts we spoke with agree that these are signs to check in with a doctor…not mask it with a fruity perfume. That way, they can rule out factors like a bacterial infection, yeast infection, or sexually transmitted infection.
All that said, as long as you stick to expert-approved areas and targeted formulas, whether or not you want to try a whole body deodorant comes down to personal preference. Unless a doctor advises otherwise, however, there’s generally no need to overhaul your entire routine even for everyday BO. No matter what, we’re going to sweat—and sometimes, we’ll smell. That’s part of being human, and no trend should shame you into believing otherwise.
