Old person smell is defined as the characteristic odor of elderly humans. Human odor undergoes distinct stages based on chemical changes initiated through the aging process. Research suggests that this enables humans to determine the suitability of potential partners based on age, in addition to other factors.
"In Japan, many believe the increased Westernization of their diet has caused additional problems with body odors."
Japanese culture places value on personal hygiene. In recent years, the Japanese have been dismayed to encounter what they call karei-shu - a type of body odor that increases with age, sometimes called "old person smell."
2-nonenal is believed to be the primary cause of karei-shu:
2-nonenal is a substance formed when fatty acid is secreted from glands and oxidizes on skin. The effects of nonenal are further exacerbated by matured skin's decreased natural antioxidant protection. This smell typically evades the cleansing effects of ordinary soaps. As people age, the odor becomes more difficult to mask. For women, karei-shu becomes more distinct after menopause and beyond.
Americans often speak of "old person smell" in homes of the elderly or nursing homes. Many have used a variety of products, including Febreeze, which helps remove the odor from some materials. Eliminating the odor from skin is an issue for many.In Japan, many believe the increased Westernization of their diet has caused additional problems with body odors. Reducing animal fat intake may help reduce karei-shu. Additionally, certain products are associated with ridding the nonenal-produced odor - from the outrageous including odor-eating suits and odor-masking gum to the practical persimmon extract like Mirai Clinical's persimmon soap bar, which eliminates the odor caused by nonenal.
Mirai Clinical (miraiclinical.com) produces and distributes cosmetics that fuse traditional Japanese ingredients with advanced science to provide personal care products in the USA. Persimmon extract has been used in Japan for centuries for its deodorizing and disinfecting benefits. Mirai Clinical's persimmon bar is handcrafted at a family-owned soap mill in Osaka. This artisanal soap requires time-consuming kneading by hand, months for the drying period and individual brushing to protect the sensitive ingredients.
Persimmon deodorant is clinically proven to eliminate odors originating from the armpit, groin, feet and nonenal. Aging odor doesn't come from poor hygiene but from deteriorated anti-oxidating defenses. Mirai Clinical is on a mission to teach westerners a successful approach to treat changing body odor that cannot be washed off with regular soaps.
Mirai Clinical's mission is to develop the most naturally safe and exceptionally effective products for body care and skin health, and is founded on the holistic Japanese practice of "less is more": the fewer products you use, the healthier your skin.
