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
Study Arms (1)
General public
This survey and ITA measurements will be performed among the general public
Interventions
Survey administration for Fitzpatrick skin type
Measurement of ITA based on SkinColorCatch instrument
