The exact cause of Brandt’s death has not been revealed at this time. His publicist would only confirm to New York Post's Page Six that Brandt “suffered from an illness.” In an update, law enforcement sources told TMZ that Brandt's death was a suicide, but didn't confirm whether he killed himself by hanging.
Mixed reports have surfaced speculating whether the “Baron of Botox” died of natural causes, or if his sudden death was caused by depression/suicide.
A reporter exclusively told Daily Mail Online that sources close to Brandt say he was “devastated” by the comparison of Martin Short’s eccentric character on the hit show “Unbreakable Kimmy Schmidt” to him, and reportedly committed suicide by hanging. Another source has told People magazine that although Dr. Brandt had been upset about the comparisons to the character, the show did not cause his apparent suicide.
"Did the show upset him? Yes. It was a mean characterization. He was a human being, no one would like that. It was making fun of him for the way he looked and it was mean and it was bullying. It was an illness, he suffered from depression," the source close to Brandt told the magazine. "It wasn't the only thing troubling him, it was just one factor."
Dr. Brandt was best known for his high-end dermatology products called "Dr. Brandt," and was one of the early proponents of Botox, even admitting to testing new treatments on himself.
“I’ve been kind of a pioneer in pushing the limits to see how things work and what the look would be,” Fredric said in a New York Times profile piece. “Would I change anything I’ve done? I might not have used as much Botox, because you don’t want to look quite as frozen.”
