"Facial time ;)," the German-born star captioned the candid snap.
On Christmas Day, Heidi posted a picture of herself wearing Christmas tree glasses and a Santa hat, posing in front of her Christmas tree.
Heidi revealed ahead of the festive period that she was planning a low-key Christmas at her home in Los Angeles and that she starts buying gifts for her loved ones several months before.
"I start in the summer!" she said. "I started everything early. I'm a planner. You have to be organised. I have lists, pages and pages of lists."
She also revealed that she prefers to receive things from her children that they have made themselves. "I want my kids to make something for me," she said. "I have a whole wall that's dedicated to all the things they've made for me."
