title: Color homogeneity and visual perception of age, health, and attractiveness of female facial skin.
abstract: BACKGROUND
  Evolutionary psychology suggests that skin signals aspects of mate value, yet only limited empirical evidence exists for this assertion.
  
  
  OBJECTIVE
  We sought to study the relationship between perception of skin condition and homogeneity of color/chromophore distribution.
  
  
  METHODS
  Cropped skin cheek images from 170 girls and women (11-76 years) were blind-rated for attractiveness, healthiness, youthfulness, and biological age by 353 participants. These skin images and corresponding melanin/hemoglobin concentration maps were analyzed objectively for homogeneity.
  
  
  RESULTS
  Homogeneity of unprocessed images correlated positively with perceived attractiveness, healthiness, and youthfulness (all r > 0.40; P < .001), but negatively with estimated age (r = -0.45; P < .001). Homogeneity of hemoglobin and melanin maps was positively correlated with that of unprocessed images (r = 0.92, 0.68; P < .001) and negatively correlated with estimated age (r = -0.32, -0.38; P < .001).
  
  
  CONCLUSIONS
  Female skin only was studied.
  
  
  CONCLUSIONS
  Skin color homogeneity, driven by melanin and hemoglobin distribution, influences perception of age, attractiveness, health, and youth.
