The infamous “old person smell” – that distinctive scent we often associate with aging skin. But is it just a myth, or is there actually science behind it? Researchers have identified the culprit as an organic compound called 2-nonenal (noh-neh-nahl), which increases in production after age 40.
As our skin ages, antioxidants decline, sebum composition changes, and UV exposure causes oxidative damage. This creates an environment where 2-nonenal can thrive. The intensity of the smell varies from person to person, depending on genetics, lifestyle, and environmental factors. While some may notice it more than others, experts say it’s a normal age-related phenomenon.
Despite its prevalence, finding a surefire way to eliminate “old person smell” remains elusive. However, using antioxidant-based cleansers and products containing tannins might help reduce odor persistence. Recent studies suggest that eggplant extract or white button mushroom extract may also have potential in reducing oxidative stress, but more research is needed.
Aging skin changes are a natural part of life, and it’s essential to focus on promoting health and well-being rather than fighting individual changes like body odor. By recognizing the wisdom and resilience that come with age, we can learn to appreciate this unique scent as a sign of aging skin, just like wrinkles or dryness.
