what happened to zac efrons face

Zac Efrons face looked visibly different in a Facebook Watch video for an Earth Day special with scientist Bill Nye in 2021, which led to speculation about whether or not he had plastic surgery or botox. However, in September 2022, Zac finally put the rumors to rest and explained that changes in his jaw happened after he suffered an accident at his home. He was running through his house, slipped, and badly hurt his chin, which caused changes in his jaw. Zac called the rumors of plastic surgery "funny" and explained that his different-looking face was due to a jaw injury in 2013, not surgery.
