Everyone has had their fair share of days. It’s an unfortunate side effect of being human. But people who have a rare version of the ABCC11 gene are immune to this stinking struggle. These lucky individuals never have to worry about offending anyone’s nostrils with their underarm aroma.

Technically, everyone has the ABCC11 gene. It’s just that some people – – carry a specific variant of the gene that makes their 24/7.

What’s the function of the ABCC11 gene? How do you know if you have it? Here’s what science has to say.

ABCC11 Gene and Body Odor: Where’s the Connection?

The ABCC11 gene is localized in the apocrine sweat glands and comes in two forms: functional and non-functional. Those who inherited the functional gene generally have wet earwax and strong body odor. On the flip side, people who have the non-functional type produce dry earwax and don't have BO.

The only way to know for sure which version of the ABCC11 gene you have is through genetic testing. Other clues may suggest you have the non-odorous gene. Check the look of your earwax. If it’s dry, flaky, and light in color, you’re probably safe from stinky pits. Even simpler, try going deodorant-free for a day and break a sweat. The answer will hit you right in the nose.

Body odor occurs when proteins in sweat interact with bacteria on the skin. Having the non-functioning ABCC11, also dubbed as the “deodorant gene,” doesn't make you sweat less, but it does lower the concentration of protein in your armpit sweat, notes the . You perspire just like everyone else but without the risk of stinky body odor.

How to Smell Good All Day

The harsh truth is a good number of people struggle with less-than-pleasant BO, be it from . It’s not the end of the world, though. Follow these tips to improve your natural scent even without the stink-proof gene.

1. Exfoliate regularly.

A buildup of dead skin cells can harbor extra bacteria. These troublemakers break down sweat into byproducts that give off a sour, cheese-like funk. Removing the layer of old skin with , , or a gentle helps keep bacteria in check and controls odor. Plus, it leaves your underarms smooth.

2. Put your trust in deodorant.

Nothing beats deodorant when it comes to reducing body odor, which is why it’s a key product in almost everyone’s . When choosing one, consider your lifestyle and what your skin needs. Roll-ons are great for women who prefer a fuss-free application, while spray deodorants are perfect for those who like a quick-dry product.

If you want to get the best of both worlds, use Dove Radiant + Care Deodorant Dry Serum 3% Niacinamide 10x Vitamin C & E Dark Marks Reducer. This dual-powered deo serum neutralizes odor and nourishes your kili-kili with as well as vitamins C and E.

3. Beware of synthetic fabrics.

Your clothing choices can affect your BO, too. Synthetic fabrics like polyester and nylon tend to trap moisture and heat, inviting more bacteria to set camp on your axilla region. When it’s hot, opt for natural fibers, such as cotton and linen, to allow for better air circulation.

3. Adjust your diet.

Certain foods can alter your sweat composition. Studies found that allium and cruciferous vegetables (think onions, garlic, cauliflower, kale, broccoli, and Brussels sprouts) contain high levels of sulfur compounds that can be excreted through your sweat glands, resulting in a putrid smell. You can still eat these food items in moderation but balanced out with fruits and chlorophyll-rich greens. Finally, drink plenty of water throughout the day to help flush out toxins.

Whether or not you have the odorless variation of the ABCC11 gene, you should still practice good hygiene. Keeping all parts of your body clean makes you feel good and wards off germs. Smelling wonderful is just a nice bonus.
