Understanding the persistence and perception of sensoryactive compounds on skin is critical for evaluating the performance of cosmetic products. Conventional sampling approaches, such as solvent swabbing, glass beads, solid Phase microextraction (SPME), and sorbent tubes, have drawbacks. They can be invasive, challenging to implement, and/or insensitive to the volatiles that drive perception. Thin film-solid phase microextraction (TF-SPME) provides a direct approach to sampling fragrance behavior on the skin surface. The flexible, high-capacity film easily conforms to the skin surface, enabling collection under real-world conditions without solvents or Skin disruption. The results reveal how formulation composition and skin interaction influence the presence and perception of volatile compounds over time. These findings offer valuable insights into product development, enabling formulators to optimize fragrance profiles and enhance consumer experience.
