On December 27, Han Shu posted a post on her official Weibo promising that no human epidermal growth factor was added to any of Han Shu's products. Han Shu said in the article that recently, reports about the company's products “Han Shu Volumizing Firming Essence Mask” and “Han Shu Whitening and Brightening Mask” added human epidermal growth factors have raised concerns among some consumers. After the report occurred, the company immediately initiated a comprehensive self-inspection and traceability process. As early as November 2025, the inspection bureau of the Shanghai Drug Administration carried out on-site inspection and testing of this product, and carried out two-way testing based on objective impartiality. The results all showed that no human epidermal growth factor components were added to the samples sent for inspection.
