I like this soap in conjunction with deodorants that do not contain an anti-perspirant component such as those containing magnesium or alpha or beta hydroxyacids. Overall its ingredients combine well and have a significant amount of research to show its affects on the noneal compound.

A lot of people notice changes in body odor as they get older or go through hormonal shifts. Unfortunately, regular soap doesn't always help with this. Sumu has strong combined the best ingredients to form a deodorizing soap with delicate and aging skin in mind.

"I'm 67 and don't think I have the smell yet but I vividly remember it from my grandmother's house and her couch. I started using Sumu as a precaution. My daughter says I smell wonderful, and I have total peace of mind now."
"My husband showers every single day, but he was starting to smell like an old man. I didn't know how to tell him. I just quietly switched his soap to Swarva. The smell is completely gone and he says his skin feels better than it has in years!"
"I care for my 82-year-old mother and was desperate to find something for that lingering smell. I didn't know it was a chemical change.. I thought she just needed more showers. Swarva worked within days. She smells fresh and feels dignified."
"I'm 71 and kept noticing a faint smell that a fresh shower couldn't fix. Even with Hibiclens. I was skeptical but desperate. After one use of Sumu, the difference was remarkable. The odor is gone and stays gone. Wish I'd found this sooner."

Most conventional soaps only wash away surface sweat and dirt but cannot properly address nonenal, the oil-based compound associated with aging odor. Our formula uses persimmon extract rich in natural tannins that help neutralize these odor molecules directly at the source instead of simply masking them.
Our Persimmon Soap eliminates Nonenal (by 97% compared to only 35% by conventional soaps), the source of aging body odor referred to as “old person smell”. Unlike other persimmon soaps that use persimmon juice (0.1% tannins), our formula uses a concentrated persimmon tannin extract that is clinically proven to eliminate all types of body odor. (in)
No, it has a light, natural scent derived from its ingredients, offering freshness without synthetic fragrances.
For best results, use the soap daily in the shower or bath.
