LOS ANGELES, July 1: Zac Efron, renowned for his roles in "High School Musical" and "Baywatch," has been at the center of speculation regarding his physical appearance, particularly his jawline. Fans first took notice during an April 2021 Facebook Watch video with Bill Nye, sparking ongoing discussions about changes in his facial structure.

It wasn't until 2022 that Efron directly addressed these speculations, clarifying that his altered jawline was not the result of cosmetic surgery but rather a consequence of a serious injury sustained several years ago. In a candid interview with Men’s Health, Efron revealed the details of the incident, which occurred when he slipped in his home and collided with a granite fountain. The impact was severe, leaving his chin bone "hanging off" his face and necessitating extensive medical intervention and physical therapy.

The recovery process, interrupted during his filming of the Netflix series "Down to Earth with Zac Efron" in Australia, led to noticeable changes in his facial muscles. Specifically, his masseter muscles, crucial for chewing and jaw movement, became enlarged as they compensated for the injury. This unintended physical transformation has been a topic of fascination among fans and on social media platforms like TikTok, where before-and-after comparisons of Efron's jawline have circulated widely.

Beyond his jaw, Efron has recently undergone significant physical changes for his acting roles. His latest projects include the Netflix romantic comedy "A Family Affair" and the Max streaming release "Iron Claw," where he portrayed famed pro-wrestler Kevin Von Erich. For the latter role, Efron undertook a rigorous regimen of weight gain and muscle-building, attaining a physique reminiscent of professional wrestlers from decades past.

Reflecting on his physical transformations, Efron emphasized the dedication required for such roles, describing months of intense training and lifestyle adjustments. Despite the challenges, he remains committed to balancing physical preparation with overall health, a lesson learned from previous experiences like his role in "Baywatch."

As Efron continues to navigate public interest in his personal and professional life, his openness about his physical journey serves as a testament to resilience and commitment in the face of both adversity and artistic pursuit.
