Lilie Masson is a French somatic psychotherapist specialising in nervous system regulation and lasting recovery from anxiety, operating under the brand Zéro Anxiété®. After living with chronic anxiety, panic attacks, and emetophobia for more than 20 years, she developed a body-based, somatic approach to healing that has become the foundation of her practice. She is the founder and creator of the registered Zéro Anxiété® method, an integrative framework drawing on polyvagal theory, Somatic Experiencing, therapeutic yoga, and Internal Family Systems. She is the author of Zéro Anxiété — 3 étapes clés pour sortir durablement du mode survie, published in February 2026 by Le Lotus et l'Éléphant, a Hachette imprint. She also hosts the French-language podcast N'attends plus, dedicated to helping listeners understand and permanently exit anxiety.
