Scientists say a natural age-related scent exists, often called “old person smell,” though the term isn’t very kind. It comes from a compound called 2-nonenal, which forms as skin produces more fatty acids and antioxidant levels drop with age. This scent can linger on skin and clothing even after washing.
Factors like tight spaces, dirty laundry, dehydration, illness, or medications can make the odor stronger. Regular exercise, clean clothes, good hydration, and a diet rich in antioxidants can help reduce it. Some countries, like Japan, even sell products designed to neutralize 2-nonenal.
Aging is normal, and these changes are too—what matters most is treating older people with care and respect.
