Cosmetotest 2026: Focusing on the exposome and skin-brain interactions

The 5^th edition of the International Symposium will take place on March 18-19, 2026, in Lyon and online. As a benchmark for R&D professionals, Cosmetotest highlights major advances in preclinical and clinical testing for cosmetic actives and products. This year’s scientific program explores cutting-edge themes, including the impact of the exposome, hormonal influence on skin and hair, and the complex skin-brain axis. A dedicated expert panel will also address new challenges in hydration. Beyond the conferences, around thirty specialized exhibitors — CROs and instrumentation manufacturers — will showcase their latest measurement solutions and in vitro, ex vivo, and in vivo test protocols.
