Matt Hancock has denied travelling to Turkey to get a hair transplant and veneers over the Christmas.
The MP for West Suffolk made the remarks after being spotted in Istanbul - which is popular destination for Brits seeking cheaper veneers and hair transplants than in the UK.
Hancock's TikTok is the latest attempt by the MP to rebrand and expand his presence on social media after appearing in I'm A Celebrity... Get Me Out of Here! in December.
On Monday, Abdul Al-Kadiri, 29, a journalist and filmmaker, posted a video of Hancock in the city on TikTok with the caption: "Matt Hancock is deffo getting a hair transplant".
"I couldn't believe it when I saw him," Al-Kadiri told the Mirror. "I was looking at him for about two minutes before I realised it actually was him.
"It was so random. He's either there for a hair transplant or to get his teeth done. You don't go to Turkey for a holiday. Especially at the moment - it's freezing."

Responding to the claims, Hancock said the story "has no teeth" and denied he was there for cosmetic surgery.
“I just got back to the office to find a journalist has called to ask if I went to Istanbul at the weekend to have a hair transplants and veneers,” he said in his own TikTok clip.
“No, I did go to Istanbul at the weekend, but this story has no teeth. It’s hair today, gone tomorrow.”
According to the Mirror, a spokesman for Hancock also said he did not buy any knock-off Calvin Kleins.
Hancock was accused of abandoning his constituents for appearing on the show, and had the Tory party whip removed - with Rishi Sunak saying "it's incumbent on politicians to earn people's respect and trust".
His own local Conservative association also asked the party not to restore his parliamentary whip after he had it removed for participating in the programme.
Weeks after, Hancock announced his intention to stand down as an MP at the next election.
"For my part, I want to do things differently," he said in a letter to the prime minister.
"I have discovered a whole new world of possibilities which I am excited to explore - new ways for me to communicate with people of all ages and from all backgrounds.
"I look forward to championing issues that are dear to my heart, including better support for dyslexic children who get a raw deal from the education system."
The former health secretary is also set to appear in Channel 4's SAS Who Dares Wins, and has announced he is releasing a book titled "Pandemic" on his his time at the department of health and social care during the pandemic.
