The science 🔬 behind fungus that keeps coming back
(explained like you're 5)
Professor Sage from the Sawumi lab had one mission: find out why itchy feet and skin folds keep flaring up, even after the cream. Here is what he found, in 6 simple steps.
The problem: fungus builds a shield
Fungus loves warm, damp places. Socks, gym kit and skin folds trap sweat all day, so feet, the groin and folds are its favourite homes.
Once it settles in, fungus builds a sticky shield around itself, called a biofilm. Think of it like a tiny umbrella.
Creams hit the umbrella and slide off. The fungus underneath stays dry and safe. That is why it clears for a week, then comes back.

Problem #2: a cream only covers one spot
A dab of cream goes on one small patch. But fungus does not stay put.
The same fungus can travel from the feet to other warm spots through socks, towels and clothing: between the toes, the groin, the folds.
So while one spot gets treated, the rest of the neighbourhood keeps the party going.

Invention #1: the shield breakers
Professor Sage put three helpers in one bar, and they work in the right order:
1. Tea tree oil (2%) and bentonite clay go after the shield.
2. Piroctone olamine (0.5%), the active trusted in anti-dandruff shampoos, gets to work on the fungus underneath.
3. Bentonite clay soaks up the sweat and moisture fungus needs to come back. Shea butter keeps skin comfortable.

Invention #2: a bar for the whole area, every day
Then he made it a soap, not a cream. A soap reaches every warm spot at once, every single day, in the shower you already take.
Lather on wet skin. Leave it 30 to 60 seconds. Rinse. Then dry completely, because fungus needs moisture. Take it away.

Tested by real people
Then the bar went out to real people: gym regulars, workers in boots all day, people who had tried every cream. One rule: swap the normal soap for this one, every day.

Frequently asked questions
Where can I use it?
Anywhere fungus likes warm, damp skin: feet and toes, groin, underarms, skin folds, back and chest.
How do I use it?
Use daily in the shower. Lather on wet skin, work it into feet, folds and other problem areas, leave 30 to 60 seconds, rinse, then dry the area completely.
Why a soap and not a cream?
A cream covers one spot. A soap washes every warm spot at once, every day, without adding a step to your routine.
Is it gentle enough for every day?
Yes. It is a cold-process bar on olive, coconut, shea and castor oils. No SLS, no parabens, no perfume.
Does it work for women too?
Yes. It is made for feet, folds and skin under the chest too. See how it works for under-breast itch.
What if it does nothing for me?
Use it every day for 30 days. If you can't see or feel the difference, email hello@sawumi.com and we refund every cent. Keep the bar.
How does the subscription work?
Bundles ship a refill every 4 weeks at our lowest price, with the free gifts. Skip, pause or cancel anytime in one click, no fees.
Is Professor Sage a real person?
No. Professor Sage is a cartoon we made to explain the science simply. The soap is real, made in small batches by Keiko Sawumi in Japan.
