A long ride, a hot run or a day in tight leggings can leave the skin around the vulva sore and raw by evening. It's a common reason people start looking at what to put on that skin, even if few people talk about it. Part of the reason it hurts so much is that intimate skin reacts differently from the skin on your arms or legs.
This article explains what chafing is and why cycling, running, walking and tight clothes cause it. It covers what helps cut the rubbing before you head out, what to do once you're home, and the signs that point to something other than chafing, which deserve a doctor's look.

What chafing is
Cleveland Clinic gives a plain definition: chafing happens when something rubs enough to wear away and damage your skin. The rubbing can come from fabric, a seam, a saddle or skin rubbing on skin. It usually shows up as redness, stinging or a raw patch, and it often burns in the shower afterwards.
The same page notes that the skin of and around the genitals is sensitive and prone to chafing. The vulva sits where the inner thighs meet and where a saddle presses, with underwear seams running right across it. It's also warm and often damp during exercise, which makes the outer layer of the skin softer and easier to rub away.
Most chafing is minor. Cleveland Clinic says it usually clears up within a few days once the rubbing stops.
Why exercise and tight clothes cause it
Friction is always the root cause, and moisture makes it worse. Sweat lets fabric slide back and forth across the skin, so a run that feels fine in cool weather can leave you sore on a humid day.
Cycling adds pressure to the mix. In a 2026 study, researchers interviewed 20 competitive female cyclists and found that saddle sores were highly prevalent, and most occurred in the vulva region. The riders linked them to pressure, friction where the body meets the saddle, and sweat. Many said finding a comfortable saddle and setup took a long time and a lot of trial and error.
Running works mostly on the inner thighs and the creases where the legs meet the body. Every stride rubs the same small area thousands of times, and a seam or a waistband that slips makes it worse.
Walking is slower but longer. A full day on your feet in jeans or leggings can rub as much as a short run, especially in heat.
Tight clothes press fabric into the skin all day. Thick seams, lace edges and thong straps sit right on the vulva and move every time you do.
How to cut the rubbing
Most of these cost nothing.
Get the fit right. Cleveland Clinic lists clothes that don't fit well among the most likely culprits. Shorts and leggings that ride up, bunch or slide around rub more than ones that stay put. For cycling, the same goes for the bike: in a review of research on saddle sores, the most often cited prevention methods were chamois cream, high quality, well-fitting cycling equipment and good personal hygiene. A saddle that's the wrong width or height can put pressure exactly where it hurts, so a bike fit is worth it if you ride a lot.
Pick fabric for the activity. For workouts, Cleveland Clinic suggests moisture-wicking fabric, because cotton holds sweat against the skin. For everyday wear, the advice flips: its page on the vulva recommends cotton underwear instead of nylon, which traps heat and moisture. So wear cotton day to day and wicking fabric when you sweat.
Check the seams. Flat seams and no lace edges in the crotch area make a real difference on a long day.
Change out of wet clothes quickly. Cleveland Clinic advises changing out of bathing suits or sweaty workout clothes as soon as possible. Sitting in damp fabric after a ride keeps the rubbing going on skin that's already softened.
Put a barrier on before, not after. Cleveland Clinic notes that anti-chafing products should go on before you're active. Cyclists often use a chamois cream made for the saddle area; runners often use an anti-chafe stick on the thighs. Whatever you use, a thin layer on clean, unbroken skin works better than a thick one.
Take breaks on long days. Standing on the pedals now and then, or a short pause on a long walk, gives the skin a rest from the pressure.
Activity by activity
| Activity | Where it usually rubs | What helps most |
|---|---|---|
| Cycling | Where the vulva meets the saddle, the inner thighs | Saddle and bike fit, padded shorts that fit, a chamois cream before the ride, changing out of the shorts right after |
| Running | Inner thighs, the creases at the top of the legs | Shorts or leggings that don't ride up, wicking fabric, an anti-chafe product on the thighs |
| Long walks | Inner thighs, underwear seams | Comfortable seams, breathable fabric, a light layer of a balm or barrier before you go |
| Tight clothes all day | The vulva and the creases, wherever seams sit | Looser cuts on long days, flat seams, cotton underwear |
| Swimming | Wherever a wet swimsuit sits after you leave the water | Changing out of the swimsuit soon after, rinsing with water |
Where a balm fits
A vulva balm is a moisturizer for the outside skin. It softens skin that feels dry and tight and helps hold moisture in. That's a different job from a chamois cream, which is made to sit between you and the saddle for hours. If you ride long distances, use a product made for the saddle during the ride.
For walks, tight clothes and the time after a workout, a balm can make the skin feel more comfortable. The Lips page lists before or after physical activity among the moments to use it, along with before bed and after the shower. One buyer described exactly this use in French: « que j'utilise quand je suis irritée ou en prévention quand je vais marcher ou porter des vêtements serrés. » She uses it when her skin is irritated, and also beforehand, on the days she heads out walking or puts on tight clothes (S., verified buyer, April 2025).
Lips goes on the vulva and surrounding skin only, never inside, and the page asks you to avoid broken skin and mucous membranes. If a ride has left a raw or open patch, skip the balm and let it settle first. Our guide on how to apply a vulva balm covers the amount and the steps.
After a ride, run or long walk
- Get out of the damp clothes as soon as you can, even before you shower.
- Rinse with lukewarm water. Water alone is enough for the vulva itself, and our article on washing the vulva explains why.
- Pat dry with a soft towel instead of rubbing.
- Let the skin breathe. Loose cotton underwear or none at all for a while gives it time to calm down.
- Moisturize skin that's intact. If the skin is red but not broken, a thin layer of a fragrance-free moisturizer can make it feel softer. Lips has no fragrance, no hormones and no petroleum.
- Leave broken skin alone. If there's a raw patch, a crack or a blister, keep it clean and dry and ask a pharmacist what to put on it.
- Give it a rest. If it's sore, a day or two off the bike or a shorter run gives the skin time to recover.
When it's something other than chafing
Most chafing fades within a few days once the rubbing stops. Some problems in the same area look similar at first but need their own care.
Saddle sores. In cyclists, a sore can be more than a rubbed patch. The saddle sore review describes them as lesions of the skin and the tissue under it, which can be short-lived or keep coming back. A tender lump, a raised spot or a sore that returns after every ride is worth showing to a doctor.
Swelling. Any swelling around the vulva that doesn't go down after a ride, or that's painful, needs a look. Our article on swollen vulva causes goes through the possibilities.
Signs of infection. Cleveland Clinic warns that infections can worsen and spread, and advises calling a provider if chafing doesn't improve within a few days or gets worse. See a doctor if you notice warmth, pus, spreading redness or a fever.
Itch with discharge or a change in smell. Sweat and damp clothes can go along with infections that have nothing to do with friction. New discharge, a strong change in smell or pain when you pee is a reason to see a doctor, and a balm isn't made for any of them.
If none of these fits and you'd like something for the outside skin on walking days and after workouts, Lips is $36 CAD ($27 USD) for a 1 oz jar, made in Montréal, and ships free on its own in Canada and the US. The ingredients and the 30-day satisfaction guarantee are on the product page.
Frequently asked questions
How do I stop chafing down there when I cycle?
Start with the fit. A saddle and bike setup that suits your body, padded shorts that fit well and a chamois cream before the ride are the methods riders and researchers mention most. Change out of the shorts as soon as you stop, rinse with water and pat dry. If a sore keeps coming back, see a doctor.
What should I put on chafed skin around the vulva?
If the skin is red but not broken, rinse with lukewarm water, pat dry and use a thin layer of a fragrance-free moisturizer on the outside skin. If the skin is raw, cracked or blistered, keep it clean and dry and ask a pharmacist what to use. See a doctor if it isn't better in a few days.
Is it chafing or a saddle sore?
Chafing is a rubbed, red or stinging patch that usually fades within a few days. A saddle sore can go deeper, showing up as a tender lump or a raised spot that may return after rides. If you notice a lump, a sore that keeps coming back, or signs of infection, have it looked at by a doctor.
Is cotton or synthetic fabric better for exercise?
For workouts, moisture-wicking fabric is usually better, because cotton holds sweat against the skin and damp fabric rubs more. For everyday underwear, cotton is the better pick, since nylon can trap heat and moisture. Whatever you wear, change out of sweaty clothes as soon as you can after exercise.
Can I use a vulva balm before running or walking?
Yes, on clean skin that isn't broken. A thin layer before a walk or a day in tight clothes is one way buyers use Lips, and the page lists before or after physical activity among the moments to use it. For long rides, choose a product made for the saddle.
How long does vulva chafing take to go away?
Mild chafing usually settles within a few days once the rubbing stops, according to Cleveland Clinic. Keep the area clean and dry, wear loose clothes and give it a short break from the activity that caused it. If it isn't better after a few days, gets worse or shows signs of infection, see a doctor.
