At its origins lies Dr. Sylvie Peres's awareness, starting in the 2000s, of the toxicity of endocrine disruptors. Deeply concerned by this public health issue, she became its spokesperson and brought together doctors in her region by creating the Association Coordination Santé Environnement du Pays Basque. Her research allowed her to confirm that pharmaceutical laboratory creams contain CMR (Carcinogenic, Mutagenic, and Reprotoxic) ingredients. Convinced of their toxicity, and concerned for her patients' health, she created her own magistral preparations in pharmacies, rich in natural active ingredients. Strongly influenced by the Paris Appeal of May 7, 2004, a historical declaration on the health dangers of chemical pollution, she relayed its message at medical conferences where she proposed natural alternatives. In an effort to prevent and improve scientific knowledge, she developed a charter that lists more than 60 dangerous ingredients. This classification work also highlights ingredients with beneficial properties for the skin.
