Vichy
At the start of the 20th century, Doctor Haller became the leader of the Vichy Thermal Center and discovered the therapeutic benefits of the volcanic water from Vichy. He utilized this rare water in cosmetic products, creating the renowned Vichy brand. Additionally, he pioneered new skincare routines by analyzing skin types, introduced the first serum in pharmacies, and developed beauty advice guides specifically for women, all thanks to his medical background.
