Optical Limits in Skin Reflectance Measurement: Quantifying Melanin-Dependent Constraints on Erythema Detection
Objective skin measurements are not automatically unbiased. Analysing 15,000+ reflectance spectra, we show that melanin progressively masks hemoglobin’s spectral signature, so visible-range erythema detection, whether by spectrophotometers, clinical cameras, or AI, loses sensitivity in the darkest skin, where data are also scarcest.
