The board currently includes four family members, Aerin Lauder, William Lauder who serves as executive chairman of the group, chairman emeritus Leonard Lauder and Aerin's sister Jane, who works as global president of Clinique, another skincare line launched under the brand.
The chief executive of the group is non-family member Fabrizio Freda who succeeded William Lauder in 2009, having previously worked as the group's chief operating officer.
"I am still so involved with Estee Lauder and right now we're between Aerin and I feel… my plate is full, but I will always, always have a place for Estee Lauder in my heart," said Lauder, speaking to Tania Bryer for CNBC Meets.

Lauder's cousin William said three of the four Lauders of his generation have chosen to work for the family business and each member has different authorities and expertise.
"Aerin's sister Jane is also working in our business and she's very successful. There's only four of us in our generation. Three of us -- myself, Aerin and Jane -- are involved in our business, my brother has chosen to take a different path and he's successful in what he's doing. The three of us each have our own lanes of authority and expertise and what Aerin is doing is something that we're all extraordinarily proud of," he said.
