I went to Dr. Topper for Botox. It did not work. I had to go back two more times for "touch-ups". It still did not work. Dr. Topper then told me I must be Botox resistant. She did not give me my money back. Meanwhile, I went to my original plastic surgeon who has always done my Botox. I told him what she said about being Botox resistant. He told me there is no such thing and that she probably diluted the Botox or did not use enough. He injected me with Botox and it worked so now I know that it is not true that I am Botox resistant.
