Yoona has been called a "CF Queen" due to her several television commercial films, and has been a spokesperson for various brands. 

Having appeared in CFs even before her Girls' Generation debut, the success of Yoona's music and acting careers have led her to individually endorsing almost 40 brands internationally, notably long-time collaborator Innisfree, including ten in 2019 alone.

CNN credited her as "one of the household names in the Asia-Pacific region" which has helped Korean beauty brands become popular in China.  

In 2012, she appeared in at least 20 commercials and was ranked fifth among celebrities with the most commercial appearances by TVCF, South Korea's largest advertisement information site.
