Skin color evaluation contributes to assessment of an individual’s cutaneous phenotype. Skin color changes provide important clues to disease progression or treatment response. Skin color is also a predictor of skin cancer risk. Melanin pigment, blood flow, skin thickness, and photoaging contribute to skin color. Melanin, hemoglobin, bilirubin, and carotene are the primary chromophores of skin color. Their concentrations vary depending on the individual’s phenotype, anatomic location, external insults of chemical irritants and UVR, and physiological changes.
