BACKGROUND/PURPOSE: Skin microrelief has been studied using various methods and devices. However, the long duration of time needed to process one sample or the expensive equipment hampered the use of those systems for routine diagnosis. Today, the emergence of new software and hardware technologies may allow this issue to be resolved.
To characterize objectively the skin surface, we introduced a new parameter SPm, namely, the area mean of superficial skin texture block formed by primary and secondary lines crossing each other. Based on the skin detector produced by the Boseview Technology Company, we developed a software for acquiring automatically skin images and calculating SPm. The relationship between SPm and age was studied on the dorsal and ventral midway of the forearm (sun-exposed and sun-protected areas) of 94 healthy volunteers without a history of smoking.
The skin surface topography can be conveniently quantified with the new parameter SPm. The value of SPm of both sites increases with age, independent of sex, with the site more exposed to light being more affected.
With the software developed, the details of the skin surface can be observed. SPm appears to be a new valid parameter for characterizing the property of the skin surface. Our method, alone or in combination with other technologies of skin topography analysis may be applied in routine diagnosis for a quantified evaluation of skin aging.
背景/目的：皮肤微地形已通过各种方法和设备进行了研究。然而，由于处理一个样本所需的时间长，或者设备昂贵，这些系统无法用于常规诊断。如今，新的软件和硬件技术的出现可能解决这个问题。
为了客观地表征皮肤表面，我们引入了一个新的参数 SPm，即由初级和次级线相互交叉形成的浅表皮肤纹理块的面积平均值。基于 Boseview 技术公司生产的皮肤检测仪，我们开发了一种自动获取皮肤图像和计算 SPm 的软件。在 94 名无吸烟史的健康志愿者的前臂（暴露和非暴露部位）的背侧和腹侧中间部位，我们研究了 SPm 与年龄之间的关系。
新参数 SPm 可以方便地定量皮肤表面形貌。两个部位的 SPm 值随年龄增长而增加，与性别无关，光照暴露部位的影响更大。
通过开发的软件，可以观察到皮肤表面的细节。SPm 似乎是一个新的有效参数，可用于描述皮肤表面的特性。我们的方法，无论是单独使用还是与其他皮肤地形分析技术结合使用，都可以应用于常规诊断，对皮肤老化进行量化评估。
