Park Eun-hye entered the entertainment industry in 1998, but she only rose to fame in 2003 with a supporting role in hit MBC TV series Dae Jang Geum (also known as Jewel in the Palace), which enjoyed tremendous popularity throughout Asia.

After a secondary lead role in 18 vs. 29, Park further solidified her status as a major Korean Wave star with the success of another period drama Yi San (2007) and her Taiwanese series Silence opposite heartthrob Vic Zhou (2006).

Park decided to star in Hong Sang-soo’s 2008 art film Night and Day even without a salary, and her performance received a Best New Actress award from the prestigious Busan Film Critics Association, her first award in ten years of acting. The next year she returned to television playing a femme fatale in daily drama Pink Lipstick.

In 2012 Park began co-hosting on cable the variety shows Queen of Beauty on KBS Drama, and Sold Out on tvN.

Park is more popular in China than in her native South Korea, as the sales of the Chinese brands she models for—Hana Cosmetics and Yonseng Tangerine Chocolates (they latter named after her character in Dae Jang Geum) — went over 25 million dollars in the year 2009.
