Abstract:	This study investigates the use of Resonant Raman (RR) spectroscopy as a non-invasive method to measure carotenoid levels in human skin, which are indicators of dietary richness in fruits and vegetables and overall antioxidant status. Traditional methods require invasive tissue removal, but RR spectroscopy offers a non-invasive alternative. The study compares two excitation wavelengths and incorporates a feedback system to adjust for laser power variations. It also examines the impact of water-filtered Infrared-A (wIRA) irradiation on carotenoid levels and background fluorescence in the skin, finding that wIRA decreases both, thereby improving the signal-to-background ratio.
