A major turning point came during the Islamic Golden Age, when the Persian physician Ibn Sina (Avicenna) refined the steam distillation process for extracting essential oils, particularly from roses. His technique, developed around the 10th century, remains a foundation of perfume production today.
In 16th-century France, tanners in the town of Grasse began perfuming leather gloves to mask the odor of their trade. When Catherine de Medici popularized scented gloves at the French court, Grasse gradually shifted from leather production to fragrance cultivation. Its ideal climate for growing jasmine, rose, and lavender helped it become the world's perfume capital, a status UNESCO formally recognized in 2018 by inscribing the region's perfumery skills on its Intangible Cultural Heritage list.
