研究概览
简要总结
The purpose of this study is to correlate subjective skin pigment measurements as reported by patient-responses to the Fitzpatrick Skin Type Scale versus objective classification of skin pigment utilizing Individual Typology Angle (ITA) measurements.
详细描述
The Fitzpatrick scale is a numerical classification for human skin color developed in 1975 as a way to estimate the response of different types of skin to UV light. It is used by dermatologists to classify skin tone and assess the risk of skin cancer.
The Fitzpatrick scale encompasses six gradings, from I to VI. However, this does not include all skin tones, as there are significantly more not encompassed within the scale. The aim of this study is to incorporate objective measurements when identifying a patient's Fitzpatrick skin type.

结局指标
主要结局
Skin colorimeter derived Individual Typology Angle value correlated against self-reported Fitzpatrick skin type
时间窗: One time - collected for up to 1 year for the entire study
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.
次要结局
- Sun protection habit use(One time - collected for up to 1 year for the entire study)
- Assess Fitzpatrick Skin type based on validated questionnaire(One time - collected for up to 1 year for the entire study)
