摘要Fitzpatrick皮肤分型是依据皮肤经一定剂量的日光照射后产生红斑还是色素及其程度,可分为6型.最小红斑量是评价皮肤分型的最重要的参数.理论上,根据光皮肤分型和最小红斑量的定义,随着光皮肤类型的增加,最小红斑量倾向于增加.然而,个体间自然光防护能力的差异,影响角质层厚度和黑素含量的基因方面因素,未曝光的部位肤色及测定最小红斑量的方法、部位等的不同,均使得两者的关系至今也尚不明确.概述近年来Fitzpatrick皮肤分型和最小红斑量的相关性研究进展.

abstractsFitzpatrick skin type is determined in accordance with the degree of erythema and/or pigmentation which develops in skin after regular doses of sun exposure.Skin is classified into six types by using this typing system.Minimal erythema dose (MED) is the most important parameter for the determination of Fitzpatrick skin type.Theoretically,MED tends to increase with the rise in Fitzpatrick skin type.However,the relation between MED and Fitzpatrick skin type remains unclear because of the differences in natural photoprotection capacity,color of unexposed skin,genetic factors affecting stratum corneum thickness and melanin content,methods and sites used for the determination of MED,etc.This review presents the advances in researches on the relationship between Fitzpatrick skin type and MED.
