Brief Summary:
Investigators plan to perform a pilot study that aims to characterize the microbiome of human vitiligo patients with both active and stable disease and compare this to the microbiome of age and sex matched controls. The investigators aim to answer the question whether the gut and skin microbiome of patients with vitiligo differs from the general population.

Primary Outcome Measures :
  1. Microbiome composition [ Time Frame: 12 months ]
    Diversity analysis of microbiome samples in control subjects versus vitiligo subjects (measured by number of bacteria species/sample)

  2. Disease Progression [ Time Frame: 12 months ]
    Disease progression in control subjects versus vitiligo subjects (measured by VASI score (0-100)).


Secondary Outcome Measures :
  1. Diet History Food Frequencies [ Time Frame: 12 months ]
    Scoring from diet history food frequency questionnaires (measured by average daily food frequency scores).
