Cortisol Biomarker Testing Validates Stress-Relief Claims
Dermatology research linking measurable cortisol levels to visible skin symptoms, including inflammation and barrier disruption, has given the category a scientific foundation it lacked just a few years ago. That research has pushed formulators to move away from vague aromatherapy marketing language toward specific, testable stress-relief claims backed by clinical biomarker data. Regulatory bodies in several major markets are now scrutinizing these claims more closely than before, rewarding suppliers who invested early in substantiation studies. The shift has effectively split the supplier base into those who can prove their claims and those still relying on marketing language alone.
