The 23-year-old actress had the fat-reduction procedure called Lipoglaze to remove "a small area" on her stomach, reports the Daily Mail.
After having the non-surgical treatment, Harmer said: "I'm very fit and healthy and have a great diet, but there was a small area around my tummy which wouldn't shift. Like everyone on Strictly I want to look good and I loved using Lipoglaze."
"I'm less than the size of an average woman."
Harmer, who's partnered with professional dancer Vincent Simone on the series, added that it upsets her when people comment on her weight. She said: "Everyone looks bigger than they are on the telly."
