No More Stinky Underboobs
I tried baby powder, deodorant, Lume — nothing lasted past lunch. For the first time in years I don't have stinky underboobs. The itching eased in a minute and the rash was gone in two weeks.

5 Years Of Prescriptions
I'd been treating this for almost five years with creams from my dermatologist. Two days on this and the red, rashy spots were calming down. By day 14 they were completely gone.

I Wore Shorts Again
My inner thighs were red, raw and itchy every summer, so I stopped wearing dresses and shorts. It doesn't sting, it isn't greasy, and this year I wore shorts.

My Folds Have Folds
My folds have folds, and the one under my stomach was always warm and smelled by lunch. Twice a day for two weeks — the redness is gone and so is the smell.

Back To Normal Skin
My underarms were dark red and burned after shaving. It feels calm again, and I didn't need a steroid cream.
The Problem
"I've Tried Powder, Deodorant & Diaper Cream.
Why Would This Be Any Different?"
Powder. Deodorant under your breasts. Diaper cream. A hair dryer after every shower. A paper towel, a folded pillowcase, even a coffee filter tucked under the fold in July. You've tried it all — and the rash is still there, because none of it
was made to treat an adult skin fold that stays hot, sweaty and rubbing 16 hours a day — especially after weight loss, a baby or menopause.
Here's what nobody tells you: that rash is often a fungus — and a fungus loves exactly what powder and diaper cream leave behind. A warm, sweaty fold. Cover it up and it just waits — and that yeasty smell comes right back.
Surface Only
Diaper Cream & Zinc Paste
The zinc helps — but it's thick, white, makes you smell like a baby and doesn't hold up in summer heat. And it isn't an antifungal.
Moisture Only
Baby Powder / Cornstarch
Dry for an hour — then it balls up into white globs in the fold and smells worse than the sweat. It doesn't treat a fungus.
Half The Job
Antifungal Powder Alone
Can help, but it cakes in a deep fold and doesn't soothe raw, rubbed skin.
Can Make It Worse
Steroid Creams
Calms the red for a day — but steroids can let a fungus grow. That's how a small rash turns into a summer-long one.
Off-Label Hack
Deodorant Under Your Breasts
Helps for a few hours — then it pills, and on raw skin in a fold it burns.
You wash your bra after one wear. You check your shirt before you leave the house. You stand a little further back in the elevator — just in case. It's not your hygiene. It's not your weight. It's sweat, rubbing and a fungus that loves a damp fold — and every week you wait, the smell gets worse and the skin it leaves behind gets darker.
That's exactly why we made Groundwork Antifungal Cream , a dry-down cream with an FDA-listed antifungal that treats the fungus, calms the itch, and leaves the fold dry — instead of just soaking up sweat.

How To Use
The 3-Step
Dry-Down System
Most women feel the itch ease within 60 seconds and the redness calm in 3–7 days —
keep going for the full 2 weeks, even after it feels better.
1
Clean & Dry
Wash the fold with mild soap and water. Lift and pat it completely dry — no moisture left in the crease.
2
Apply A Thin Layer
Apply a thin, even layer over the rash and the skin around it, all along the bra line.
3
Let It Dry Down
It dries into a silky, powder-like finish — no white paste, nothing on your bra. Use morning and night for 2 weeks.
Results Timeline
Relief In 60 Seconds.
Cleared In 14 Days.
Here is what to expect when you use it twice a day for 2 weeks.
No risk: try it for 30 days. Not better? We pay you back.
First Use
It goes on light and dries down. The itching eases within 60 seconds.
Day 1
The fold feels drier through the day — and that yeasty smell starts to go. Keep the area clean and dry.
Days 2–3
The itching usually calms down. This is where most women stop — and why it's back next month. Keep going.
Days 4–7
The redness fades as the fungus clears. Don't stop yet — the fungus leaves after the itch does.
Day 14
Finish the full 2 weeks. No risk: try it for 30 days — not better? We pay you back.

"Years of a red, itchy rash under my breasts — and the smell. My bras smelled like I'd been sweating out all my fears. Powder turned to paste and deodorant stung. This dries down, the itching eased in a minute, the smell went away, and now I don't think about it all day.
Margaret
Under-Breast
"After my baby, my boobs were always sweaty and stinky, and the fold under my belly stayed red and damp. It didn't sting on my raw skin, and it calmed down within the first week.
Jennifer
After Baby
"I lost 60 pounds and got a rash I'd never had — in folds I didn't have before. Powder turned to paste. I followed the 2 weeks and finally have normal skin again.
