The BBC Breakfast sports presenter has had a chin-reduction procedure called a Strawberry Lift to “tidy any flabby loose skin”.
The non-surgical procedure uses a pain-free treatment to reduce fat cells and form new collagen, aiming to lift and tighten the neck and facial jowls.
Mike told MailOnline of his decision to undergo the treatment: “I think it’s just with Strictly and losing weight I wanted to tidy any flabby loose skin. And I was intrigued by this natural process.
“I was intrigued to use the Strawberry Lift and not undergo invasive surgery on my chin line.
“And I wanted to look after my appearance as I approached 54.”
Mike lost a stone and a half during his time on Strictly, where he was partnered with professional dancer Katya Jones and described competing on the BBC show as “an absolute honour and a joy”.
“I have had the most amazing nine or 10 weeks since we started training,” he said during his time on the show. “I have lost a stone and half. I’m a guy in his 50s, I’m mentally sharper, I feel able to deal with pressured situations - thanks to the dance-offs!
“It has changed me completely and honestly I’m not going to stop dancing.”
Mike will be back in the ballroom this weekend as the current series of Strictly reaches its climax.
Strictly Come Dancing concludes on Saturday at 7.05pm on BBC One.
