But from now on, Porcaro said, they won't be taking any chances.
"We've already instituted a policy. If someone doesn't leave a photo identification at the time they register, they won't be seen. Plain and simple. No license or photo ID, they're not seen, period."
But Porcaro wished it didn't have to be this way. He said his staff usually takes the patients who come in at "face value." But perhaps that is not the best way to deal with people looking to change their faces.
"It's unfortunate that we have to resort to these kind of measures," Porcaro said. "It's supposed to be a fun process for the patient and for me."
While injecting small doses of the cosmetic form of botulinum toxin into patients' faces might not be everybody's idea of fun, Porcaro said it's his passion.
"I love to see patients come back after treatment I've given them," he said. "It's not just a question of cosmetic improvement, it improves the quality of their life, it improves their self-esteem, it improves how they react to family and friends, and how they see themselves. It's a reincarnation."
