Post anything about the rash under the breasts, and the tips pour in. Cornstarch. Deodorant. Diaper cream. A hair dryer on cool. Vicks. The salve farmers put on cows.
“100 posts, 100 suggested cures, each working for one person, none working for all.”
A woman left that line under one of our posts.
I read those comments too. Hundreds of them. Almost every tip does something real. The trouble is, each one does one thing. A fold with a rash needs three things done at once.
Here are the 7 tips women share most, what each one gets right, and why each one stops working.
Reason 1
Every tip works for someone. That’s the problem.
These are real comments, word for word, from under our posts. Every woman who wrote one meant it. It worked for her, at least for a while.
But a skin fold rash isn’t one problem. It’s three. The fold stays wet. Skin rubs on skin. And yeast grows in the wet.
Under the breasts, under the belly, between the thighs. Wherever skin folds over skin, the same three problems show up together.
A tip that fixes one of them helps for a few days. Then the other two bring the rash back.
Reason 2
The four tips we see the most.

Cornstarch

Deodorant

Diaper cream

Hair dryer
In one month of comments under our posts, these came up again and again:
Four good ideas. Each one fixes one piece. So the rash keeps coming back.
Reason 3
Cornstarch and powder: dry for an hour, paste by lunch.
Powder is the oldest tip of all. Grandma said cornstarch. The drugstore says Gold Bond.
Even the women who love it say what happens next. One wrote: “Yeah it cakes up at first from the moisture it’s absorbing.”
Powder soaks up sweat until it can’t hold any more. Then it turns to paste, and the paste holds the heat and the wet right against the skin.
And powder has nothing in it for the yeast. It dries the fold for a while, but the yeast is still there.
Reason 4
Diaper cream: good for sore skin, no help with yeast.
Desitin, Butt Paste, Triple Paste. Plenty of women swear by them.
Diaper cream is zinc oxide in a thick paste. Zinc is good for sore skin. But that thick paste sits in the fold and holds the heat in. One woman called Desitin “extremely messy to use.”
And there’s nothing in it to kill yeast. Diaper cream was made for a baby’s bottom, not for a fold that stays wet all day.
Reason 5
The doctor’s tips: a foot cream, and a fan.
Some tips come from doctors. “My primary dr suggested something for athletes foot,” one woman wrote. Another: “Doctor told me to lie down naked on a bed with the fan on me.”
Both are half right. The rash is usually yeast, which is a fungus, and a foot cream kills fungus. A fan dries the fold.
But a foot cream was made for feet, and feet get air. In a fold that’s shut all day, the cream just sits there wet. The yeast grows back in a few days. And nobody can lie under a fan all day.
The doctor isn’t wrong about what it is. The tools just weren’t made for a fold.
Reason 6
Line the tips up, and you can see the gap.

Moisture

Friction

Yeast
Here’s what each tip handles, and what it leaves behind:
Problem
Tips that handle it
What they leave behind
Moisture
Cornstarch, powder, deodorant, hair dryer
The yeast. And the wet is back by lunch
Friction
Diaper cream, a sock or washcloth under the bra
Trapped heat and trapped wet
Yeast
Foot cream, Nystatin, dandruff shampoo
A wet fold, so it grows right back
Every tip is in this table somewhere. Not one of them is in all three rows.
That’s why the rash keeps coming back. You need one thing that does all three at once.
Reason 7
The one thing that does all three.
Healora Intertrigo Relief Cream was made for skin folds. It has a real antifungal for the yeast. It has drying ingredients for the wet. And it leaves a barrier, so skin stops rubbing skin. You smooth it on like a cream. It kills the fungus, then dries down to a powder, and you get dressed.
Phase 1 - It takes on the wet
(the first few minutes)
Witch hazel pulls moisture out of the fold. Silica and tapioca starch keep soaking up sweat through the day, without caking. It goes on like a cream, then dries down to a powder, so the fold stays dry.
Phase 2 - It kills the yeast
(days 1-5)
Undecylenic acid (10%) kills the yeast, the part powder and diaper cream never touch. Tea tree oil, held in tiny capsules, helps with the smell. Most women feel no sting, even on sore skin.
Phase 3 - It keeps it away
(after that)
Zinc oxide (15%) leaves a breathable barrier between the two sides of the fold. Skin stops rubbing skin. A thin layer after the shower keeps it that way.
A pea-sized amount covers the whole crease. No steroids. No artificial fragrance. In Healora’s customer survey, 96% said their rash healed within 24 hours, and half of them said overnight.
One tube in place of the whole drawer.

"Before using Healora I constantly suffered from severe redness, irritation, and pain. Nothing worked except Desitin, which is extremely messy to use. Your product was a lifesaver and unlike Desitin I don't have to constantly reapply it."

"I've tried everything. I used to tuck washcloths under my bra to absorb moisture. Frequent showers. Powders just caked goopy. Ointments meant for athletes foot and jock itch just made everything wet with temporary relief."

"The assorted baby powders to apply to folds underneath breast area and under armpits, just created a cakey mess due to perspiration. ... Then comes healora which was soothing on the skin as I applied to my problem areas without any type of powder and the areas eventually cleared up."

"I have used prescription cream, and gold bond powder that has worked for a day and then I'm back to the same situation. However with Healora the infection is gone and doesn't come back."
