Abstract

Skin phototype classification is very important to the dermatologist. It can be used for carrying out a risk assessment for some skin diseases and estimating the treatment parameters in phototherapy and laser. Mminimal erythema dose (MED) testing is generally accepted method for assessing skin phototypes; however, this procedure is very complicated and time consuming. Currently, Dermatologist usually assesses the pateint’s skin color by classification according to Fitzpatrick system. dermatologist and others, including (1) self-assessment using a Fitzpatrick Skin Score questionnaire and (2) constitutive and facultative skin color measures with the colorimeter. This cross-sectional descriptive study included 336 Thai patients. The patients were requested to complete the Fitzpatrick skin score questionnaire, then evaluate the skin phototype by the dermatologist and be measured their skin color in both sun exposed and unexposed area. Statistically significant correlations between self-assessment phototype and dermatologist-assessment phototype were found. Colorimetric values of constitutive and facultative skin color were also useful for phototype classification group especially the melanin index (M).
