Zac’s newest appearance, which saw him in a basic white t-shirt alongside co-stars Jeremy Allen White and Harris Dickinson, quickly went viral. Many people inquired, “What happened to his face?” and bombarded the internet with inquiries and remarks like, “His face is huge now,” “What happened to his jaw?” and “His face doesn’t even move now.”

Others quickly made comparisons and found similarities between Efron, David Hasselhoff, and Rob Lowe. Someone said, “Woah, he looks like the villain in Avengers: Endgame,” and another said, “I could see him being the Joker.” However, several admirers defended the actor, explaining that his jaw was damaged in a car accident and that he underwent surgeries to have it reconstructed, which is why he looks different now.

He just appears like he has gained weight. If this is accurate and the cause is the jaw accident, I feel bad for him. I hope he didn’t try to “fix” his already gorgeous looks and make things worse. I would say he is still a good-looking guy, but his tiny face was stunning.This is not the first time the 17 Again actor’s image has provoked online discussion.

People asked why the actor’s lower part of his face looked so different in April 2021, when he appeared in Facebook Watch’s “Earth Day Musical.”
When Efron appeared on the cover of Men’s Health magazine in October 2022, he finally stated why he underwent the metamorphosis. He told the magazine that he cracked his jaw while sprinting around his residence wearing socks. He slipped and smacked his chin against the hard corner of a stone fountain.

During his recovery, the High School Musical star said that some face muscles attempted to compensate for the injury. He collaborated with a physical therapist to assist with this. When he took a vacation from therapy, he discovered that his jaw muscles, known as masseters, were significantly larger.
