People ask us what they can use on skin folds, the groin and the bikini line to feel fresh on a hot day, after a workout or late in a long shift. It's a reasonable question with a fairly simple answer, as long as you keep two things apart: the skin on the outside, and the vagina itself.
Odour from skin folds is about sweat, warmth and air, and there's plenty you can do about it. A change in vaginal odour is a different matter, and it's covered in our article on why your vulva can smell different some weeks. This article sticks to the skin: why folds hold odour, what helps, what to keep away from vulvar skin, and when to see a doctor.

What body odour actually is
Sweat on its own doesn't smell. Cleveland Clinic puts it simply: body odor is what you smell when your sweat comes in contact with the bacteria on your skin. The bacteria break down what's in the sweat, and that's where the smell comes from.
Not all sweat is the same. Most of the body has glands that make a thin, watery sweat for cooling. A second kind, called apocrine glands, opens into the hair follicles, and Cleveland Clinic notes that you can find them in the groin and armpits. Their sweat is the kind that picks up a smell once it meets skin bacteria.
Having a natural body odour is normal. The same page points out that it isn't always linked to how much you sweat, which is why two people can sweat the same amount and smell quite different.
Why folds, underarms and the groin hold it
Skin folds are the places where two areas of skin touch: under the arms, in the groin, between the buttocks, under the breasts and under the belly. They share three features that make odour more likely, and DermNet, the dermatology reference, describes them well.
They're warm. DermNet notes that skin in the folds has a relatively high surface temperature.
They stay damp. Sweat and moisture from the skin can't evaporate when the fold is closed, so it sits there.
They rub. Skin moving against skin causes friction, and over a long day that can lead to chafing.
Warm, damp skin with some friction is exactly where skin bacteria have the most to work with. That's why the groin and underarms tend to smell sooner than your forearm, even when you're equally clean. If rubbing is a bigger problem than odour for you, our article on chafing from cycling, running or tight clothes covers that side.
What helps
Most of what works is free and has to do with moisture and air.
Wash, then dry completely. Washing removes some of the bacteria and the sweat they feed on. Drying matters just as much. DermNet advises that physical exertion should be followed by bathing and completely drying skin flexures, and suggests a hairdryer on a cool setting for the underarms and under the breasts. Pat the folds dry with a towel and give them a minute of air before you dress.
Wear fabric that breathes. Cleveland Clinic recommends loose-fitting clothing made of cotton, and says the same applies to underwear and bras. The NHS adds that it helps to wear natural fabrics like cotton, wool and silk, and avoid tight clothing and manmade fabrics.
Change out of damp clothes. Gym clothes and swimsuits keep moisture against the skin. Changing soon after a workout makes a difference.
Keep the vulva simple. On the vulva itself, plain warm water is enough. Our article on whether you need to wash your vulva explains what to use and what to skip.
| What helps | Why it works |
|---|---|
| Washing the folds daily and after exercise | Removes some of the sweat and bacteria that make the smell |
| Drying the folds completely | Moisture that can't evaporate gives bacteria more to work with |
| Cotton or other natural fabrics | Lets the skin breathe instead of trapping sweat |
| Changing out of damp clothes | Takes moisture off the skin sooner |
| Plain warm water on the vulva | Cleans without stripping sensitive skin |
What to keep away from vulvar skin
Products made to cover up a smell are where most of the trouble starts on intimate skin.
Fragrance. Scented washes, wipes and sprays are a common reason intimate skin reacts. Cleveland Clinic notes that deodorants generally work by masking body odor with a more pleasant-smelling fragrance, and that's the part vulvar skin tends to dislike. Our article on fragrance in body wash goes into why.
Douching. Rinsing inside the vagina can upset its natural balance. ACOG, the US organization of obstetrician-gynecologists, is direct about it: do not douche, it is better to let the vagina cleanse itself.
Feminine hygiene sprays and full body deodorants. On the same page, ACOG advises against feminine hygiene sprays, full body deodorants and scented tampons. We think that's worth saying plainly in an article about a spray, and the next section explains how ours differs and where it should and shouldn't go.
Underarm antiperspirant. Antiperspirants reduce sweat, and Cleveland Clinic notes that the active ingredient in most of them is aluminum. They're made for the underarms, not for the vulva.
Where a spray fits, and where it doesn't
If the vulva itself is your only concern, you don't need a spray at all. A healthy vulva has its own scent, so there's no need to make it smell like nothing.
Where a spray can help is the skin around it and elsewhere on the body: the underarms, the folds of the groin and under the breasts, and the outside of intimate areas, on a day when you can't shower right away. That's the job we made Mist for.
What's in it: peppermint hydrosol, spearmint hydrosol, glycerin, alpha-glucan oligosaccharide (a prebiotic), inulin (a plant-derived prebiotic) and potassium sorbate.
What's left out: no fragrance and no aluminum salts. That makes it a different thing from the deodorants Cleveland Clinic describes, which mask odour with fragrance, and from antiperspirants, which use aluminum to reduce sweat. Mist helps neutralize odour and leaves a fresh feel, with no rinsing and no residue.
How to use it: spray it on clean skin or through the day, on the underarms, skin folds, face or the outside of intimate areas, as often as you need. Let it dry before you dress. It's for external use only, so keep it away from the eyes and mucous membranes, and never spray it inside the vagina.
It's made in Montréal and comes in a 2 oz (60 mL) bottle for $32 CAD ($24 USD for US readers). The ingredients and directions are on the Mist page.
Our buyers use it in more places than we expected. Some tell us they use it as an underarm deodorant.
One wrote about another moment entirely: « C'est bien si tu veux le mettre avant une date et t'as pas eu le temps de prendre une douche. ;) » (C.G., October 2025). In English: it's handy before a date when you haven't had time to shower.
A spray is a quick fix between showers, and it doesn't replace washing and drying. If you're reaching for it many times a day to cover a smell that keeps coming back, that's a reason to look at the cause, which the next section covers.
When a smell is a doctor question
Some smells aren't about sweat at all, and no spray is the right answer for them.
A new or strong change in vaginal odour. ACOG lists itching, burning, a bad odor, or a large amount of discharge among the signs of vaginitis, and a strong fishy odour is the main sign of bacterial vaginosis. These need a diagnosis and, often, a prescription. A spray would only hide the signal.
Odour with discharge, itch or burning. Any of these together with a change in smell is a reason to see a doctor or a sexual health clinic.
A rash in a fold that's red, raw or not clearing. DermNet notes that a rash in the folds can become infected, and that an infected fold can cause a foul odour. That needs a doctor, not a product.
A sudden change in your usual body odour. Cleveland Clinic lists a sudden change in body odor or an increase in sweating as a reason to contact a healthcare provider. The NHS also suggests seeing a GP if you notice a change in how your odour usually smells.
None of these is a spray question. A spray is for a fresh feel on healthy skin.
Frequently asked questions
Can you use deodorant on skin folds?
You can use a gentle product made for that skin, on clean, dry skin. Look for one with no fragrance, and keep underarm antiperspirants for the underarms. Washing and drying the folds completely, and wearing breathable fabric, do most of the work. A red, raw or itchy rash in a fold is a reason to see a doctor.
Is it safe to use deodorant on the vulva?
The vulva doesn't need deodorant. A healthy vulva has its own natural scent, and plain warm water is enough to clean it. ACOG advises against feminine hygiene sprays and full body deodorants, and fragrance is a common reason this skin reacts. A fragrance-free spray belongs on the skin around it, never inside the vagina.
Why does my groin smell even after I shower?
The groin has apocrine sweat glands, the kind whose sweat picks up a smell from skin bacteria, and it's warm and closed off from the air. Sweat can build up again within hours, especially in tight or synthetic clothing. Drying completely after washing and wearing cotton help. A smell that's strong, new or comes with discharge or itch needs a doctor.
How do you stop odour under the breasts or belly?
Wash the fold daily and after exercise, then dry it completely: pat it with a towel or use a hairdryer on a cool setting. Wear a cotton bra or top that lets air reach the skin. If the skin turns red, raw or starts to smell foul, see a doctor, since an infected rash in a fold needs treatment.
What is the difference between a deodorant and an antiperspirant?
A deodorant works on the smell, while an antiperspirant reduces how much you sweat. Cleveland Clinic notes that most antiperspirants use aluminum as the active ingredient. Many deodorants mask odour with fragrance. Mist has no fragrance and no aluminum salts, and it helps neutralize odour.
When should I see a doctor about a smell down there?
See a doctor if the smell is new, strong or fishy, or comes with discharge, itching, burning or pain. Those can be signs of an infection that needs a diagnosis. A sudden change in your usual body odour is also worth checking. Never try to cover these with a spray or a wash.
