Body wash
Why women lean in
Regular body wash only cleans the surface of your skin. Beneath it, trapped 2-nonenal oils oxidize and turn sour. Layering cologne on top creates a heavy funk within two hours that drives women away. Kojiderm's Japanese persimmon tannins dissolve those trapped oils, so your natural persimmon-clean skin scent draws her in.
See why ordinary grooming fails while Japanese persimmon keeps her close.

JAPAN ENGINEEREDThe Japanese persimmon heritage
Japanese soap makers perfected persimmon tannin extract to solve the stubborn, oil-based compound that regular cleansers miss. By purifying trapped oils beneath the surface, Kojiderm reveals a clean persimmon-fresh skin scent that draws people closer without synthetic fragrance or greasy buildup.
Lead Formulator
"Most men think they need stronger cologne. They don't. The smell comes from oils trapped under the skin that regular soap never touches. When we built Kojiderm around persimmon tannin, the goal was simple: wash that out at the source, so a man just smells clean — like himself, only better."

Verified customer ratings
Men say it's the first soap that actually gets rid of the smell — not just covers it.
"I'm 41 and I've always used a lot of cologne. Switched to this bar three weeks ago and stopped spraying. Now my girlfriend keeps putting her face in my neck and asking what I'm wearing. It's just the soap. Crazy."
"I lift five days a week and my shirts used to smell sour even after a shower. Two weeks with Kojiderm and that old musk is gone. Feels clean all day, not perfumed."
"I'm 56 and my wife said my pillow had a smell. Nothing worked. One month with this bar and she told me the pillowcase smells fresh now. Wish I found it years ago."
"Hot summer train every morning. Before, I'd get to the office feeling gross. Now I wash my neck and chest with this and I stay fresh through lunch. Light scent, no heavy stuff."
"My skin gets dry and itchy with most bars. This one leaves it soft. The persimmon smell is subtle and clean. Ordered the 5 pack."
"First date in a long time. Showered with Kojiderm, no cologne. She leaned in at dinner and literally said 'why do you smell so good?' That's all I need to say."
