On July 24, 2016, Everipedia cofounder Mahbod Moghadam got a zit after about 6 months of no zits.  He was almost 34 years of age, which led him to believe he would stop getting zits, but this was not the case. At the time, he hadn't gotten a zit on his forehead for over a year, as more recent zits had been in the chin or neck area, which is standard as one begins to age. 
Moghadam believed the zit was the result of summer heat, as the previous weekend had seen record temperatures, and also from debris in the air from the Sand Fire, a fire that took place earlier that week. On the day before the zit sprouted, Moghadam had accidentally taken a 2-hour nap on his foam roller after getting back from the gym and sweating. [✔]
While one may deduce from the given description that this zit was a result of acne mechanica, it appeared to be a pustule pimple. 
The zit died on July 26, 2016.
