Kaley Cuoco learned a valuable lesson the hard way: never experiment with Botox right before filming a sitcom.
During a recent podcast appearance, the Big Bang Theory star revealed that her first-ever Botox treatment left her unable to move her face during an episode that required exaggerated expressions.
“I was literally doing jokes and nothing moved,” Cuoco said, recalling the moment. “My forehead was frozen. It looked terrible.”
The timing couldn’t have been worse. Cuoco explained that she had just gotten the injections the same week she was shooting, leaving her struggling through scenes while pretending everything was fine.
Looking back, she called it a wake-up call that made her rethink how much cosmetic work she was doing.
“That’s when I thought, ‘Okay, let’s rein it in,’” she said.
While she still embraces Botox in moderation, Cuoco now avoids her forehead altogether — a decision shaped by one very memorable on-set experience.
