What CausesΒ Older Adult Smell?

Sebaceous glands in skin releaseΒ sebum, an oily combination of lipids that helps retain moisture. The sebum produced is broken down by bacteria on the surface of the skin, which contributes toΒ body odorΒ and can be exacerbated by hormonal changes and stress. In younger people, skinβs natural antioxidant defenses work to prevent these fatty acid breakdown products from beingΒ oxidized by the airΒ and turned into other chemicals. Older skin has fewer antioxidants. That, coupled with hormonal shifts that increase lipid production by sebaceous glands, means that more of those free fatty acids will undergo oxidation. The results is an accumulation of oxidized substances including the particularly odiferous nonenal.
Because theyβre not water soluble, the lipids that give rise to nonenal donβt wash off easily with regular soap. The company that Dr. Brannon works for, a Japanese skincare brand called Mirai, makesΒ a body wash that specifically targets nonenalΒ with persimmon extract. The tannins in the extract absorb up to 97 percent of the compound on the skin, according to Miraiβs clinical trials.

The older we get, the more nonenal we produce. And, because nonenal is a small, volatile compound, it can be found in the air around skin, and absorbed into clothing, pillows and sofa cushions. All the while, our sense of smell deteriorates, making us less aware that itβs happening. So if someone gives you a gift certificate to Mirai for your birthday, take the hint.
