METHODS: This study included 198 Korean volunteers (126 females and 72 males) with Fitzpatrick skin types II, III, or IV. Fourteen different anatomical areas on the face were divided into facial erythema units. Each unit was scored from one (least erythematous) to five (most erythematous) according to the observed level of erythema on the red images implemented as hemoglobin content. We also evaluated the presence of facial telangiectatic macules.
RESULTS: On average, the perinasal, nasal, and cheek units were the most hypervascular regions. In contrast, the degree of facial erythema was lowest in the labial (perioral), neck, and temporal regions. The average value of erythema was higher in males than in females. Additionally, the severity of erythema tended to increase with age. In both males and females, the number of telangiectatic macules increased with age.
CONCLUSIONS: We analyzed the clinical characteristics of erythema in healthy subjects with Fitzpatrick skin types II, III, or IV in the Korean population. This study is expected to be used to identify the neurovascular pathogenesis of the most common regions of facial dermatosis in the future.
方法:这项研究包括198名韩国志愿者(126名女性和72名男性)的FitzpatrickII型皮肤,III,或者IV.将面部的14个不同解剖区域分为面部红斑单位。根据在实施为血红蛋白含量的红色图像上观察到的红斑水平,从一个(最少红斑)到五个(最多红斑)对每个单位进行评分。我们还评估了面部毛细血管扩张斑的存在。
结果:平均而言,perinasal,鼻部,脸颊单位是血管最多的区域。相比之下,面部红斑的程度在唇(口周)最低,脖子,和时间区域。男性红斑的平均值高于女性。此外,红斑的严重程度随着年龄的增长而增加。在男性和女性中,毛细血管扩张斑的数量随年龄增加而增加。
结论:我们分析了患有II型Fitzpatrick皮肤的健康受试者红斑的临床特征,III,或IV在韩国人口中。这项研究有望用于确定面部皮肤病最常见区域的神经血管发病机制。
