Does aging affect body odor

As people age, their skin naturally produces a chemical called 2-nonenal, which causes a distinct odor often referred to as "old person smell." This change results from the oxidation of skin oils and occurs gradually, starting around middle age, though everyone experiences it differently. Experts emphasize that this odor is a normal part of aging and not related to poor hygiene, with studies indicating it is less unpleasant than commonly perceived. While there’s no way to prevent 2-nonenal formation, maintaining good skin health and a healthy lifestyle can manage its presence, and there is no reason for individuals to feel self-conscious about these natural changes.
