For the rash under your breasts, under your belly, and between your thighs. The one that comes back every time you sweat.
Your Antifungal Cream Is Working. That's the Problem.
It clears the rash and leaves the fold exactly as wet as it found it. So the first hot day, the first long shift, the first bra you can't take off until 6 p.m., it's back. A dermatologist explains why, and what he gives his patients instead: a steroid-free cream that treats the fungal cause and dries down to an invisible, powder-soft barrier in about 60 seconds, so the fold stays dry while the rash clears.
- No steroids: no rebound, no thinning skin
- No grease, no white paste: dries to a powder-soft finish, nothing on your bra
- No prescription, no diaper-cream aisle: ships in a plain sage-green box that says Intertrigo Relief Cream and nothing else
One tube lasts about 6 to 7 weeks on one area. One-time purchase unless you choose Subscribe & Save.
Works under the breasts · under the belly and apron fold · groin and inner thighs · underarms · neck fold · anywhere skin meets skin
If you've ever folded a paper towel under your bra band, this page is for you.
Or a panty liner. Or a washcloth under your belly. Or stood in the bathroom with the hair dryer on cool, or slept on top of the covers with a fan pointed at your chest, or put deodorant somewhere deodorant was never meant to go.
You shower twice a day. You pat dry, you don't rub. You've bought the cornstarch, the Gold Bond, the Lotrimin, the Desitin, the little stick that's supposed to stop chafing, the prescription tube the doctor handed you with a "keep it dry and wear cotton." You have a drawer of half-used miracle creams to prove it.
And every summer, every long shift, every heatwave, every wedding in August, it comes back anyway. Red. Raw. Burning when you sweat. And that smell you're terrified someone else can notice.
So here's the first thing you need to hear, and it comes from a board-certified dermatologist, not a brand:
It's a skin condition with a name, intertrigo, and it happens to thin women with large breasts, to new mothers, to nurses on twelve-hour shifts, to women in their seventies, and to women who lost eighty pounds and got folds they never had before. It happens for one reason, and the reason is physics, not character.
Any place skin sits against skin, under a bra band, under a belly, between two thighs, is a sealed pocket. Warm. Dark. Wet. No airflow. Sweat goes in and can't evaporate out. Add friction, and you've built the exact climate that yeast needs to grow.
That's the whole cause. Not you. The fold.
And once you see it that way, you can finally see why everything you've bought keeps failing you, and why it was always going to.
The nightly ritual: a paper towel strip, folded and tucked under the band
"It works, then it's back the second I sweat." That sentence is the entire story.
Every woman with this rash says some version of it. Most of them think it means something is wrong with them. It doesn't. It means every product on that shelf was only ever doing half the job. Because there are two jobs, not one:
The hair dryer on cool, every night. It still comes back.
Now look at what you've been using:
Every one of them was designed for a different body part. Diaper cream is built for a baby who gets wiped clean and changed every three hours. Foot creams are built for a foot inside a sock. Chafing sticks are built for a runner's thigh. Nobody built the product for a warm, wet, airless adult fold that stays closed under a bra for twelve hours.
So the rash clears, and the fold is still wet, still warm, still sealed. The conditions that grew it are untouched. Of course it comes back. It isn't your body failing the cream. It's the cream recreating the swamp it's supposed to fix.
You've probably also heard that cornstarch "feeds yeast." Whether or not that's true (the research is mixed), the real problem with powder in a fold is simpler: the moment it gets wet, it stops absorbing and starts holding.
Nurses don't smother a raw fold in cream. They do something else, and it's the whole secret.
Ask any wound-care nurse what she does for a patient with a raw skin fold at 3 a.m. She doesn't reach for a thick layer of anything. She does the opposite:
A wicking cloth in the fold. A thin film of zinc and antifungal, not a slab of paste. Re-dry it at every turn. That's the standard of care in hospitals and long-term care, and it works because it does both jobs at once: treat it, and keep it dry.
The problem was never the ingredients. Zinc oxide has protected skin for a century. It's in every hospital barrier cream and every grandmother's tin. The problem was the texture. Zinc oxide in petrolatum is a paste. A paste seals. And you can't keep a fold dry with something that seals it wet.
Intertrigo Relief Cream is that nursing practice, in one tube, in one step.
It goes on like a light cream. Then, in about 60 seconds, it dries down into an invisible, powder-soft barrier: the dryness of a powder, without the mess, the caking, or the white ring on a black dress. That barrier keeps the fold dry through a shift, a hot day, a night's sleep. And while it does, an FDA-recognized antifungal gets to work on the cause.
Two jobs. One cream. About a minute.
Get Dry and Clear: 30-Day Guarantee
What a wound-care nurse actually does: dry it, treat it thin, keep it dry.
The texture, in three frames
Two proven actives. One plant. Finally built for the fold.
Zinc Oxide
The same skin protectant nurses, hospitals, and a hundred years of nappy creams have trusted, but in a matrix that sets to a powder-soft finish instead of sitting there as a white paste. It shields raw skin from friction and keeps moisture from pooling in the fold, without a film, without residue, without staining your bra.
Undecylenic Acid
A fatty acid cracked from castor oil. It was first studied for fungal skin infections in the late 1930s and put to work in the 1940s, when fungal skin disease was sidelining troops in the heat and humidity of the Pacific, the closest thing to a skin fold the military ever fought. It has been recognized by the FDA as an over-the-counter antifungal for decades and has sat in athlete's-foot products ever since. It has never been built into a cream designed for women's skin folds. Until now.
Microencapsulated Tea Tree Oil and Witch Hazel
For soothing and freshness. We name them plainly because some women are sensitive to tea tree oil. If that's you, see the FAQ below before you order. The encapsulation is designed to release gently rather than hit raw skin all at once.
A charming footnote: the "zinc and castor oil cream" in the British formulary has treated nappy rash for a century. Two ingredients, one plant, finally together for grown women.
What you actually receive
One 50g / 1.76oz slim squeeze tube with a white flip-top cap, small enough for a purse, a scrub pocket, or a nightstand, in a matching sage-green box. Both read "Intertrigo Relief Cream." Neither says anything you'd be embarrassed to have on the bathroom counter or the porch.
From the dermatologist who stopped writing the steroid script
I wrote the script hundreds of times. Clotrimazole-betamethasone, "keep it dry, wear cotton," next patient. Then those women came back. The redness was gone, but the skin in the fold was shiny and thin. A few had escalated to cellulitis. Most simply stopped coming back and went to Reddit instead.
The turning point was my own mother. She was 71, in a care home after a hip fracture, and the aides "just put powder on it." I saw the fold under her breast on a Sunday visit and realized the medicine I'd trained in was written for the complications, not the daily misery before them.
The wound-care nurses on her floor were doing something no product in the drugstore did: dry it, treat it thin, keep it dry. In one step, in one tube, that product did not exist.
I found undecylenic acid in the old literature, an 80-year-old FDA-recognized antifungal that nobody had put in a cream for the fold. Then the real work started: eleven formulations before 15% zinc oxide would dry down instead of seal.
The first woman who used it told me: "I put my bra on and forgot about it." That sentence is the whole goal.
Dr. Richard Hayes
Three things Dr. Hayes wants you to know:
What happens in the first 60 seconds, and at 6 p.m.
A light, cooling cream. It spreads thin and doesn't drag on raw skin. No menthol tingle. No alcohol sting. This is the question women ask before any other, "will it burn?", and the formula was built around the answer.
It sets. Touch it: dry. Powder-soft. Invisible. Put your bra on.
The barrier stays put through sweat, movement, and friction. No pilling into little white balls. No paste on the band.
Dry skin, a clean band, and, for a lot of women, the first time in years, nothing to smell.
6 p.m. The bra comes off. Nothing to think about.
About that smell.
Most skin-fold rashes aren't one organism; they're yeast and bacteria together in a wet pocket, which is why an antifungal alone can clear the red and leave the odor behind. A fold that stays dry is a fold that can't host either. That's the difference between "treated" and "feeling clean."
A word on tea tree oil and witch hazel
Both are in this formula, both are named on the box, and both are encapsulated to release gently. Most women with raw skin feel cooling, not stinging. If you have a known tea tree sensitivity, this isn't the product for you, and we'd rather tell you now than have you find out later.
Built for every fold, not just one.
Under the breasts
The bra band sits exactly in the fold; sweat has nowhere to go; the rash smells by mid-afternoon
Keeps the band line dry; no paste on the bra
Under the belly and apron fold
Often can't see it, sometimes find it by smell; the deepest, wettest fold on the body
Sets thin enough to reach and stay
Groin and inner thighs
Chub rub that turns into a rash; summer dresses off the table by June
Dries fast; won't rub off on underwear or wear off by noon
Underarms
Shaving irritation plus deodorant plus sweat
Sheer layer, no interference with deodorant
Neck and other folds
Overlooked and constantly rubbing
Same thin barrier, same 60 seconds
For the women it was really built for
The nurse on a twelve. The new mom whose breasts suddenly sit on her ribs. The woman whose night sweats started this at 48. The woman who lost the weight on a GLP-1 and got folds no one warned her about. The daughter buying for her mother in care, whose aides "just put powder on it."
The only cream on the shelf doing both jobs.
The drawer of half-used remedies, and the one tube built for the fold.

An honest timeline.
Cooling on contact, dry to the touch in about a minute. The burning quiets because the fold is finally dry, not because anything has been numbed.
The raw, "on fire" feeling settles as skin stops rubbing wet-on-wet. The itch backs off. Keep applying twice a day, thin.
Redness fades as the antifungal does its work on a fold that's no longer feeding it. Many women notice the smell is gone before the color is.
Skin looks like skin again. Keep a thin layer on through the season. This is the part every other product skipped. Keeping the fold dry is what keeps it from starting over.
Individual results vary. If your rash is hot, spreading, streaky, or you have a fever, see a doctor. That can be a bacterial infection that needs treatment.
"The only thing that's worked for me."
Twelve-hour shifts in a sports bra and I'd tried Lotrimin, then Desitin on top of it. By lunch the band was wet and I was stuffing a paper towel in there again. This goes on before my shift, it's dry before I finish my coffee, and at 7 p.m. the band is clean and the skin is dry. First summer in years I haven't dreaded July.
I couldn't see the fold under my stomach. I found it by the smell, which is humiliating to type. Two weeks of a thin layer morning and night and the smell went first, then the red. Now I just do it after my shower and honestly forget about it.
Chub rub that turned into a rash every June and put my summer dresses away until September. The chafing stick melted in my purse and the powder turned to paste. This one dries fast and doesn't rub off on my underwear. Wore a dress to my niece's wedding in 105 degrees. Held all day.
The Gold Bond burned so badly I cried, and the steroid cream my doctor gave me made the skin shiny and thin. I was scared to put anything on raw skin. This went on cool. No sting at all. That was the whole reason I ordered a second tube.
Bought it for my mother in assisted living, where the aides were just putting powder on it. Her aide now puts a pea-sized amount on after her morning wash and it stays dry until evening. Mom says it's the first thing that hasn't stung her.
Lost 70 pounds on a GLP-1 and got folds nobody warned me about. The prescription tube worked for three days and then it came back angrier. Three weeks on this, twice a day, thin like the box says, and I'm back in leggings. No white ring on my black ones either.
Pick the size that matches your summer.
First, the number every woman asks for: one 50g tube, used as directed (a pea-sized amount, twice a day, spread thin), lasts about 6 to 7 weeks on one area, or 3 to 4 weeks on two. That's roughly 55 to 65 cents a day at the single-tube price, less on the bundles, and less again on Subscribe & Save. Less than the powder-plus-Lotrimin-plus-Desitin routine, and it doesn't cost you a $50 bra every month.

The questions women ask before they buy, answered straight.
Does it sting on raw, cracked, or weeping skin?
It was formulated not to. There's no menthol, no alcohol, no fragrance. It goes on cool and sets dry. If your skin is open and weeping, apply an even thinner layer the first day or two. The barrier does the work, not the amount.
It has tea tree oil. I've been burned by tea tree before.
Yes, it does, and we say so on the box. It's microencapsulated to release gently rather than all at once, and at this concentration most women feel cooling, not stinging. If you have a known tea tree allergy, please don't order, and if you're unsure, do a patch test on the inside of your wrist first. The guarantee covers you either way.
Is it a steroid? Will it thin my skin?
No, and no. There are no corticosteroids in it. That's the reason it exists.
I've tried everything. Why would this be different?
Because everything you've tried did one job. Antifungals treat and leave the fold wet. Pastes seal it wet. Powders cake. This one treats the cause and dries down to a barrier that keeps the fold dry, the two-job approach nurses use at the bedside. If your rash has been coming back for years, that's the pattern of a one-job product, not an unfixable fold.
Does it stain bras, shirts, or sheets?
No. It sets to an invisible, powder-soft finish in about a minute. Nothing transfers to the band, and there's no white ring under a black top.
Cream or powder? I hate powder mess. / I only trust powder.
Both of you get what you want. It goes on as a light cream, so there's no cloud of dust and nothing to sweep off the bathroom floor. Then it sets like a powder: dry, soft, matte, without ever turning to dough when you sweat.
How much do I use, and how often?
A pea-sized amount per area, spread to a sheer layer, twice a day: morning before you dress, and after your evening shower. Thin is the whole method.
How long does a tube last?
About 6 to 7 weeks on one area at twice a day; 3 to 4 weeks on two. The 50g tube is slim enough to keep one in your bag or scrub pocket and one at home.
Can I put my bra on right after?
Give it about 60 seconds to set. Then yes.
Can I use it every day, all summer? Or only during a flare?
Every day. Keeping the fold dry between flares is exactly what stops the next one from starting. It's designed for daily use on adult skin.
Can I wear it with deodorant or antiperspirant in the fold?
Yes. Apply the cream first, let it set, then anything else on top.
Does it help with the smell?
The odor comes from what's growing in a wet fold. A fold that's dry and being treated is a fold that stops smelling. Most women notice that before they notice the redness fading.
Does it work in real humidity, under a sports bra, through a 12-hour shift?
That's what it was built for. The barrier stays put through sweat and friction; that's the difference between it and the sticks that melt and the powders that cake.
Is it safe if I'm diabetic? For my elderly mother's thin skin? While breastfeeding?
It's steroid-free and formulated for daily adult use, but we're not going to give you medical advice on a sales page. If you're diabetic, pregnant or nursing, or buying for someone with fragile skin or a medical condition, read the full ingredient list on the box and check with your doctor or pharmacist. Keep it away from the nipple if you're nursing.
What is undecylenic acid? I've never heard of it.
An antifungal fatty acid derived from castor oil, studied since the 1930s and recognized by the FDA as an over-the-counter antifungal active for decades. It's been in athlete's-foot products for 80 years. You haven't heard of it because nobody ever put it in a product for you.
Which dermatologist?
Dr. Richard Hayes, MD, FAAD, board-certified dermatologist. His photo, credentials, and story are above.
Is this a subscription?
No. Everything on this page is a one-time purchase by default. Subscribe & Save is an optional toggle in the offer above: 30% off, delivered monthly, and you can cancel, pause, or adjust it at any time from your account or by emailing support.
Will the box say something embarrassing?
The box is sage green with leaf line-art and says "Intertrigo Relief Cream." It looks like skincare, because it is.
How does the guarantee actually work?
Email us any time within 30 days of delivery, however much of the tube you've used. We refund what you paid. You keep the tube. No forms.
The goal isn't "cured." The goal is the day you forget about it.
Not the day the rash is gone. The day you put your bra on at 6 a.m., work a full shift in July, take it off at 6 p.m., and realize you didn't think about it once. Didn't stuff a paper towel. Didn't duck into a bathroom. Didn't wonder if anyone could smell you.
You've spent years doing everything right with products built for babies, feet, and marathon runners. This one was built for the fold, by a dermatologist who got tired of writing the steroid script, around the two-job practice nurses already use, with an antifungal that's been trusted for 80 years and a barrier that finally learned how to dry.
One slim green tube. About 60 seconds. Thirty days to decide if it was worth it.
