What is Cuir Vitessence?
Cuir Vitessence is a fragrance base developed by Symrise, meaning it is a aroma chemicals designed to deliver a consistent, nuanced leather-suede impression. Unlike single-molecule ingredients, a base functions as a ready-to-use building block, offering reliability, ease of use, and strong performance across formulas.
