Nonetheless, Japanese companies have set out to rid the world of it. Another line of Japanese anti-aging odor products, Mirai Clinical , uses persimmon extract as a natural deodorizer against it. The tannin in the fruit dissolves Nonenal in a similar way lemon juice knocks out a fishy smell.
Mirai Clinical sells body washes and soap designed to eliminate the problem. And as skin matures, its natural antioxidant protection decreases, resulting in greater oxidation of lipid acid. When lipid acid is oxidized, the chemical compound Nonenal is produced. Maybe not. That said, they may forebear other changes that do warrant attention. Instead, it may just be the result of interactions between skin gland secretions and bacteria living on your skin.
The type of bacteria that live on your skin are different in various life stages. Likewise, the chemicals and compounds in your body can change with time, too.
But experts believe evolution is part of the picture. Infants, teenagers, young adults, and middle-aged adults each tend to have slightly different body odors. Experts believe these specific scents help keep the human species alive and well. For example, that fresh baby smell may be more appealing to mothers, which helps with bonding.
Since the discovery of 2-noneal, several companies have started developing personal care products designed to mask the scent of older people, particularly in Japan. In fact, that study found that participants rated the odors of older individuals as less unpleasant and less intense than the odors of some younger groups.
For the study, 44 men and women were divided into three different age categories: 20 to 30, 45 to 55, and 75 to They were asked to sleep in a shirt specially fitted with underarm pads that could absorb odor for five consecutive days. These included foods containing a lot of spices.
At the end of the five days, the underarm pads were collected and cut into quarters. Each piece was placed in a glass jar. The testers had a hard time detecting differences in scent between young and middle-aged people — they smelled too similar. Any scented product you enjoy will help mask the smell. Alternatively, consider wearing your new scent as a badge of honor.
