    Area of Science:

    • Anthropometry
    • Dermatology
    • Biophysics

    Background:

    • Skin color is a complex trait influenced by genetics and environment.
    • Quantifying skin pigmentation objectively is crucial for various scientific disciplines.
    • Understanding variations in skin color can provide insights into human adaptation and diversity.

    Purpose of the Study:

    • To objectively measure and analyze skin color using spectrophotometry.
    • To investigate potential sexual dimorphism in skin pigmentation.
    • To assess differences in pigmentation variability between sexes.

    Main Methods:

    • Skin color was measured using reflectance spectrophotometry at specific wavelengths (426, 550, and 685 nm).
    • Spectrophotometric data were processed using logarithmic and antilogarithmic transformations for analysis.

  • Statistical methods were employed to compare color parameters between sexes.

    • Main Results:

    • The study detected statistically significant differences in skin color between males and females, indicating sexual dimorphism.
    • Variability in skin pigmentation was found to be dissimilar between the sexes.
    • Specific wavelength measurements and their transformations revealed distinct pigmentation patterns.

    Conclusions:

    • Skin color exhibits sexual dimorphism, with measurable differences between males and females.
    • Pigmentation variability is not uniform across sexes, suggesting distinct biological or environmental influences.
    • Reflectance spectrophotometry provides a reliable method for quantifying skin color and its variations.
