How do I know if I have Nonenal?

Nonenal, a natural compound that's created when skin oils oxidize, is characterized by a greasy or musty smell. This usually happens after 40 when a decline in our skin's antioxidants occurs due to aging.

What if it doesn’t work for me?

Persimmon Tannins vs. Persimmon Juice

Test tube comparison: Mirai soap shows persimmon tannins in amber liquid, while fake soap shows clear liquid with no tannins

Persimmon Tannins vs. Persimmon Juice

Having “persimmon” on the label doesn’t mean every formula is the same. Mirai Clinical uses concentrated Japanese Persimmon Tannins specifically formulated for deodorizing not simply persimmon juice. We don’t just source the formula. We are the lab behind it.

What is Nonenal? The Cause of 'Old People Smell™'

What is Nonenal? The Cause of 'Old People Smell™'

As we age, natural oils on the skin oxidize more easily, creating Nonenal® (green molecule), an aging odor compound that can cling to the skin.

Clinically Tested to Reduce Nonenal® by Up to 97%

Bar chart comparing odor reduction: Mirai removes 97% of Nonenal vs 35% for others, plus higher reduction of five other odors

Clinically Tested to Reduce Nonenal® by Up to 97%

Ordinary soap can wash away sweat and everyday odor, but Nonenal® is different. Mirai Clinical’s formula was clinically tested to reduce Nonenal® by up to 97%, targeting the stubborn odor associated with aging.

Where Nonenal Occurs

Unscented - Mirai_Clinical_5_steps

Nonenal builds up behind the ears and back of the neck. Oil glands are dense there, hair traps warmth, and it's easy to miss when you wash.
