'Old Person Smell' Is Real, And Science Will Dictate Whether It Happens To You

Dermatologists tell HuffPost that a compound called 2-nonenal, an aldehyde, increases in human skin production after age 40 and becomes more pronounced in the 50s and beyond, producing the scent colloquially known as 'old person smell.' Experts attribute the change to declining antioxidant defenses, shifting sebum composition, and accumulated UV and environmental damage to skin over decades.

Multiple dermatologists quoted in the piece stress that the phenomenon affects people broadly regardless of sex, that intensity varies by genetics and lifestyle, and that the smell may register as neutral or even pleasant rather than unpleasant. The article also notes people producing the scent may not notice it themselves because of nasal habituation.
