Park Ji-yoon recently revealed through her personal SNS that she often hears people say her skin has improved. She posted a video herself, saying, "Lately, I've been hearing a lot that my skin has gotten better," and mentioned that she also feels the change. However, she is not sure about the cause of the change and added, "I will experiment a bit more and let you know once I have a definite answer."

Park Ji-yoon mentioned two reasons for her skin improvement. She has been drinking freshly blended fruit juices recently, and as another secret, she cited tuna for dieters. Although she feels she gained weight after her trip to Fukuoka, she also said her body feels lighter.

Ahead of the Lunar New Year holiday, she succeeded in losing weight and revealed, "The first digit has changed," mentioning that she recorded her lowest body weight.

Park Ji-yoon married Choi Dong-seok, a fellow KBS announcer from the 30th class in 2004, in 2009. The couple filed for divorce mediation in October 2023 after 14 years of marriage, and it was later revealed that they also filed counter-lawsuits against each other.
