I don't think, for example, Arai fiberglass-based shells degrade. Not sure about older (and maybe current) generation polycarbonate shells though.
The other thing to consider are the rubber-based components like seals, and the vinyl wraps around the straps and mouth guard area, if applicable. I had the vinyl strap wraps crack and crumble with bits of black clinging to my mug. Again, another helmet area heavily exposed to skin protein and uric acid excretion.
