XEXYMIX appointed Ko Yoon-jung as its brand model on the 4th of last month. The sales figures are based on the eight products Ko Yoon-jung wore in the campaign.

XEXYMIX attributes this sales growth to the “Ko Yoon-jung effect.” The brand notes that Ko Yoon-jung’s sophisticated image naturally aligns with its stylish athleisure aesthetic. The company also believes that the campaign’s focus on the functionality of her outfits—which are well-suited for outdoor activities—has helped drive demand.

A company representative stated, “Ko Yoon-jung’s unique, bright, and healthy charm effectively conveys the stylish athleisure look that XEXYMIX pursues, leading to increased sales of key items.” The representative added, “Given the high level of interest and positive reactions every time campaign content is released on our official social media channels, we plan to continue showcasing XEXYMIX’s distinctive, functional, and sophisticated style in a variety of ways alongside Ko Yoon-jung.”
