The 39-year-old dancer - who returned to the judging panel on the BBC show this weekend after two weeks quarantining - said while it was good that the BLM movement had sparked conversation, what matters most is continuing that long-term.
Mabuse told Woman and Home magazine: "It’s good that people are having the Black Lives Matter conversation. It’s important this is not just a trend. Being Black is not a hashtag.
"I want to see sustainable and long-term change, not just talk."
The South African star currently lives in Germany where she has a dance school and has appeared as a judge on the German versions of Strictly and Britain’s Got Talent.
Mabuse - whose younger sister Oti Mabuse is a professional dancer on Strictly - said she does not underestimate the importance of being a Black person on primetime television.
She added: "I am one of the very few Black people in Germany on TV, and on the BBC. I understand my responsibility of representing Black people and I don’t take it for granted."
Mabuse was absent from Strictly for two weeks to enable her to self-isolate for an urgent trip home to Germany.
She revealed on Instagram that there had been an attempted break-in at the dance school she runs with her husband Evgenij Voznyuk, and so she returned to the country to help with police enquiries.
Strictly pro dancer Anton du Beke - who has long been tipped for a judging role on the show - stood in for Mabuse in her absence.

His celebrity partner former Labour home secretary Jacqui Smith was the first person to be sent home this year.
Du Beke said: “Thank goodness they gave me that job. My ego was around my ankles after getting booted off first this year.”
