The story when this beauty line was created was when Ha Ji Won was filming for Hwang Jini; she had a very hectic schedule, which prevented her from visiting her dermatologist regularly, which resulted to her skin being unhealthy. Due to this, she and her friend June You Gyeong who is an aromatherapist, decided to create natural beauty products that will help women like Ji-Won who couldn't visit a derma take care of their skin on their own.

At first, the beauty line named "The Queen's Beauty" originally started with green clay that serves as a scrub and moisturizer. However, the brand eventually expanded and became a full line that includes balms and skin oil.
