Skin Pigment
Conditions
Brief summary
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.
Detailed description
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.

Inclusion criteria
* Male and females that are 18 years of age and older * Subjects with all Fitzpatrick skin types I-VI One-third of subjects will be Fitzpatrick I or II skin types, one-third of subjects will be III or IV, and one-third will have V and VI.
Exclusion criteria

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Skin colorimeter derived Individual Typology Angle value correlated against self-reported Fitzpatrick skin type | 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. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Assess Fitzpatrick Skin type based on validated questionnaire | One time - collected for up to 1 year for the entire study | Questionnaire about sun sensitivity and tanning will be administered to calculate the Fitzpatrick skin types |
| Sun protection habit use | One time - collected for up to 1 year for the entire study | Quantification of sun protection habits based on survey question asking their typical use of sun protection |
