Outcome Measures

Primary Outcomes (1)

  • Skin colorimeter derived Individual Typology Angle value correlated against self-reported Fitzpatrick skin type

    Correlation of ITA by the use of SkinColorCatch (Delfin) compared to the Fitzpatrick skin scale as determined by the patients' responses to validated questionnaire. The higher the ITA, the lighter the skin. ITA skin color types are classified into six groups, from Very Light to Dark skin.

    One time - collected for up to 1 year for the entire study

Secondary Outcomes (2)

  • Assess Fitzpatrick Skin type based on validated questionnaire

    One time - collected for up to 1 year for the entire study

  • Sun protection habit use

    One time - collected for up to 1 year for the entire study
