2065438+September 2009, some netizens broke the news in Weibo that Qiwei was suspected of endorsing a slimming paste, but the slimming paste was actually an unapproved drug. Later, because the ingredients of the slimming cream were unknown and there were potential safety hazards, it was sealed up and removed by the state drug regulatory authorities. Qiwei himself later issued a statement on the Weibo, saying that he had never endorsed any slimming products or drugs, and said that he would actively cooperate with the investigation of relevant departments to safeguard his legitimate rights and interests. However, according to online rumors and related media reports, the weight loss stickers endorsed by Qiwei are fake.

Endorsement of slimming products has been one of the profit models between stars and mass enterprises for many years. However, when celebrities and enterprises endorse weight-loss products, they need to abide by relevant laws and regulations to ensure the safety and effectiveness of the products.
