Cumulative but with a repair mechanism. There's not necessarily "rollover exposure".

  There are temporary as well as permanent effects and the repair mechanism can be overwhelmed: photoaging, age spots, mutations.

    Right but there are common precautionary rule-of-thumb heuristics which lead normal people to believe that every sun exposure brings them a little closer to death. That's exaggerated. Or at least, the claims are widely contested.

      Lets be honest here, every additional sun exposre means you lived longer which directly leads you closer to death sooooo ;P
