Tatcha appoints Diane Kim as new Chief Executive Officer
The move addresses recent management transitions and aims to provide stability amid Unilever’s portfolio strategy.
JAPAN – Tatcha, a Japanese-inspired skincare brand owned by Unilever, has appointed Diane Kim as its new CEO, effective February 9, 2026, following the departure of former CEO Mary Yee in October 2025.
Kim brings extensive experience in prestige beauty, having most recently served as an industry advisor at Advent International since 2024, with prior roles including global brand president for Laura Mercier, bareMinerals, and Buxom at Orveon Global, as well as senior marketing positions at The Estée Lauder Companies.
This leadership change comes after Tatcha’s acquisition by Unilever in 2019 for approximately USD 500 million, positioning the brand for continued growth in premium skincare.
Diane Kim’s career spans over two decades in luxury beauty and fashion, including global president roles at Eve Lom and Kevyn Aucoin under Space NK from 2017 to 2021.
Her expertise in scaling brands, digital engagement, and international expansion aligns with Tatcha’s ambitions.
This appointment emphasizes Tatcha’s push for global expansion, particularly in the UK, Europe, and Asia, leveraging Kim’s brand-building track record to drive international scale.
Industry observers view this as a step toward enhanced leadership continuity and market penetration in key regions.
Tatcha offers a curated range of luxury Japanese-inspired skincare products, including cleansers, moisturizers, serums, treatments, and body care, all centred on gentle, antioxidant-rich formulas.
Their bestsellers include The Dewy Skin Cream, The Silk Cream, The Essence, and The Rice Wash.
In a similar way, Syensqo recently confirmed that Mike Radossich has formally taken over as CEO and joined the company’s Board of Directors, with his appointment effective January 1, 2026.
He steps into the top role following the tenure of Dr Ilham Kadri, who will remain in a special advisory capacity to provide continuity and help manage a smooth handover of responsibilities.
The company characterizes Radossich as a long‑serving executive with deep familiarity with Syensqo’s global operations and extensive experience running businesses across the organization.
The company also noted that he is expected to steer the next phase of the speciality materials group’s development, emphasizing long‑term performance, sustainable growth and value creation for stakeholders.
