Christine Hamilton said she hoped to look 21 again as she underwent cosmetic surgery live on TV.
She had "filling injections" on her face during Gloria Hunniford's Channel 5 daytime show.
The injections are non-toxic and are designed to remove unwanted lines on her top lip.
The wife of former Tory MP Neil Hamilton said before the surgery she had high expectations.
She said: "I expect the world. I want everything. I hope to look about 21."
Later, she described the experience as "amazing".
Mrs Hamilton said she might get hooked on the treatment if she was not careful.
She said: "It's amazing. It feels very peculiar, because it feels like I've had an anaesthetic."
"Well, the lines have gone. I'm gonna get hooked on this."
