Factors that influence the appearance of the smell of old people:
Hormonal changes
Oxidation of fatty acids in the skin
Decrease in cell renewal
High-fat or low-antioxidant diet
Lack of ventilation in clothing or closed spaces
Main causes of old man odor
1. Production of 2-nonenal
It’s a substance generated when unsaturated lipids in the skin oxidize. This compound has an aroma similar to wet cardboard or rancid oil.
2. Decrease in natural oils
With age, the skin produces less sebum, which changes its pH and microbiome, facilitating more noticeable odors.
