“…This topography includes several sizes of undulation [11]. Among these, microrelief, representing a certain size of undulation that consists of sulci cutis (or skin furrows) and cristae cutis (or skin ridges), is often utilized in evaluations of skin condition [6,[12][13][14]. From the perspective of appearance, microrelief is a fine structure so that each furrow and ridge can barely be recognized at the level of an individual structure.…”

“…For example, the primary lines deepen and broaden while the secondary lines distort or even disappear [5]. To establish an objective and quantitative assessment of these skin surface variations, skin surface parameters (Std, Entropy, MA, and NI) related to skin image primitive features are mainly investigated in this paper.…”

“…Although the replica analysis had advantages, they had many disadvantages which limit these methods for skin assessment. For example, this method was an indirect measure of the skin surface topography [4], which preparation of skin replicas was complicated and time-consuming, and the devices (e.g., laser profilometry) are usually expensive [5]. Therefore, a direct and flexible method without replicas for measuring skin surface topography was critically needed in skin aging research.…”

Abstract. This paper presents a model of detection age which quantifies the appearance changes of human skin at different stages of aging without traditional skeleton. We provide a novel method to extract age-related primitive features from skin surface images obtained by a digital camera, including skin surface heterogeneity parameters of the standard deviation of gray (Std) and the information entropy (Entropy) of skin images, the skin surface texture variations parameters of the mean area of the grids (MA) and the number of intersections (NI). Skin surface images of 97 individuals have been analyzed by our image processing program. The results show that the four parameters were statistically correlated with age, indicating their potential for the routine evaluation of skin aging.

“…Since the water content of the superfi cial portion and barrier function constitute the vital functional characteristics of the SC that covers the skin surface, these measurements are generally performed in combination. Recently, for evaluating skin surface morphology, or skin texture, imaging analysis using replicas has also been utilized (10).…”

Skin roughness is a term commonly used in Japan to describe a poor skin condition related to a rough and dry skin surface that develops as a result of various damaging effects from the environment or skin inflammation. Recovery from skin roughness requires skin care for a long period, thus it is important to prevent development of such skin changes. PROTECT X2 contains agents used for a protective covering of the skin from frequent hand washing or use of alcohol-based disinfectants. These unique components are also thought to be effective to treat skin roughness of the dorsa of the hands and heels. In the present study, we evaluated the effectiveness of PROTECT X2 to increase skin surface hydration state, as well as enhance the barrier function of the stratum corneum of the dorsa of the hands and heels in elderly individuals. A total of 8 elderly subjects and their caretakers without any skin diseases participated in the study. They applied PROTECT X2 by themselves to the dorsum area of 1 hand and heel 3 to 5 times daily for 1 month, while the opposite sides were left untreated. We measured stratum corneum (SC) hydration and transepidermal water loss (TEWL) before beginning treatment, then 1 week and 1 month after the start of treatment to compare between the treated and untreated skin. SC hydration state after applications of PROTECT X2 was 1.5-to 3.0-fold higher than that of the untreated skin in the dorsa of both hands and heels, indicating that the moisturizing ingredients accompanied by water were replenished in those areas where the cream was applied. Also, TEWL in the dorsum of the hands was 17.0-27.9% lower on the treated side, indicating improvement in SC barrier function. On the basis of these findings, we concluded that PROTECT X2 enhances waterholding in the SC and aids the barrier function of the skin in the dorsum of the hands. In addition, we consider that this formulation is useful for not only protecting the hands from the effects of such agents as detergents and alcohol-based disinfectants, but also for protecting heel skin covered by a thick SC from dry and cold conditions such as those encountered in winter. However, since the SC in that area is much thicker than that of the hands, the barrier function was not significantly improved within 1 month of daily treatments.
