  • In this study, 20 middle-aged women aged from 35 to 55 were studied from October 12, 2020 to November 15, 2020 to find out the effects of improvement of facial skin of Jinyeosoo Clean Mist. Among the 20 participants, 10 were divided into experimental group and 10 control group. The Janus facial skin scope system (PSI Co.) used on the skin to measure pore, wrinkles, elasticity, UV pigmentation, and skin tone observed depending the difference in light sources. The facial examination took place 10 minutes after cleansing to stabilize and a total of 4 examinations were carried out after every week of using Jinyeosoo Clean Mist for 4 weeks. For statistical processing, SPSS statistics program 21.0 was utilized to compare the mean averages of pre-experimental and post-experimental data from the above two groups - the experimental group that used Jinyeosoo Clean Mist (hydrogen ion mist) 1 and 2 and the control group that did not use the subject products - and the corresponding sample t-test was used. As a result of the analysis, the group that used Jinyeosoo Clean Mist showed difference in pores (t=3.280, p<.05), wrinkles (t=4.353, p<.01) and elasticity (t=3.003, p<.05), skin tone(t=3.280, p<.01) under the statistical significance level.

  • Skin, the complex membrane that holds the body together, also embraces the full spectrum of design today-from product to architecture, fashion, and media. Every object has a skin. thick or thin, smooth or rough, porous or impermeable, the skin is the line between a hidden interior and an exterior we experience. Skin: Surface, Substance and Design is a compendium of products, furniture, fashion, architecture and media that expand the limits of what we understand as surface. Reflecting the convergence of natural and artificial life, this provocative a thesis shows how enhanced and simulated skins appear everywhere in today's world.

  • Since 1990s the concern on essence and inside has transferred onto the surface and its style. The longing for plastic surgery and skin beauty might prove this fervent tendency. Furthermore the development of digital media and technology as well as high-tech material enabled this hope to be real in the realm of design. All these progresses and transitions toward the surface introduced more creative and novel phenomena of furniture design arena around its surface. The rising of surface has evolved through architecture, interior design and furniture. The surface of furniture can be easily transposed into the human skin. And it acquires the aspects of skin's metaphoric and symbolic meaning. The characteristics of skin effect in furniture design can be summarized as material aspects, relational aspects, and formal aspects. Material aspects shows skin's elasticity and smooth plane. Relational aspects express the reactive functions of skin. Formal aspects represent organic power through surface.

  • Background For patients with neuropathy, vasculopathy, and impairment of wound healing, treatment of a diabetic foot ulcer poses many challenges. A large number of dermal analogues have been invented in an effort to overcome these challenges. Matriderm, a dermal analogue, is made from bovine collagen and elastin. This study was conducted in order to evaluate the effectiveness of Matriderm for treatment of diabetic foot ulcers, in comparison with skin grafting. Methods Sixty patients with diabetic foot ulcer were included in this prospective study. The average age of the patients, who had type II diabetes mellitus, was 58 years old. The patients were allocated to an experimental or control group with their consents. The patients were selected with their consent for inclusion in an experimental group and a control group. Patients in the experimental group received a Matriderm appliance and a split-thickness skin graft, while those in the control group received only a split-thickness skin graft. Results A shorter hospitalization period (7.52 weeks) was observed in the experimental group than in the control group (9.22 weeks), and a shorter period of time (8.61 weeks) was required for complete healing, compared with the control group (12.94 weeks), with statistical significance (P<0.05). A higher elasticity ratio of the affected side to the non-affected side was observed in the experimental group, compared with the control group (P<0.01). Conclusions Matriderm enables effective healing and improves elasticity in treatment of patients with diabetic foot ulcer.

  • Background: Red ginseng contains components, including microelements, vitamins, essential oils, and fatty acids, that can be used in skincare to delay the aging process. We investigated the effects of red ginseng treatment on skin elasticity by assessing cellular stiffness and measuring collagen protein synthesis. Methods: Human dermal fibroblasts were treated with red ginseng, and the resulting changes in stiffness were investigated using atomic force microscopy. Cytoskeletal changes and mRNA expression of biomarkers of aging, including that of procollagens I and VII, elastin, and fibrillin-1, were investigated. Collagen in a human skin equivalent treated with red ginseng was visualized via hematoxylin and eosin staining, scanning electron microscopy, and atomic force microscopy. Results and conclusion: The stiffness of fibroblasts was significantly reduced by treatment with red ginseng concentrations of ≥ 0.8 mg/mL. The ratio of F-actin to G-actin decreased after treatment, which corresponded to a change in fibroblast stiffness. The storage modulus (G') and loss modulus (G'') of the skin equivalent were both lowered by red ginseng treatment. This result indicates that the viscoelasticity of the skin equivalent can be restored by red ginseng treatment.

  • Background Mastectomy in male transgender patients is an important (and often the first) step toward physical manhood. At our department, mastectomies in transgender patients have been performed for several decades. Methods Recorded data were collected and analyzed for all male transgender patients undergoing mastectomy over a period of 24 years at our department. Results In total, 268 gender-reassigning mastectomies were performed. Several different mastectomy techniques (areolar incision, n=172; sub-mammary incision, n=96) were used according to patients' habitus and breast features. Corresponding to algorithms presented in the current literature, certain breast qualities were matched with a particular mastectomy technique. Overall, small breasts with marginal ptosis and good skin elasticity allowed small areolar incisions as a method of access for glandular removal. In contrast, large breasts and those with heavy ptosis or poor skin elasticity often required larger incisions for breast amputation. The secondary correction rate (38%) was high for gender reassignment mastectomy, as is also reflected by data in the current literature. Secondary correction frequently involved revision of chest wall recontouring, suggesting inadequate removal of the mammary tissue, as well as scar revision, which may reflect intense traction during wound healing (36%). Secondary corrections were performed more often after using small areolar incision techniques (48%) than after using large sub-mammary incisions (21%). Conclusions Choosing the suitable mastectomy technique for each patient requires careful individual evaluation of breast features such as size, degree of ptosis, and skin elasticity in order to maximize patient satisfaction and minimize secondary revisions.

  • Skin properties are influenced by a variety of internal or external factors. This study was conducted to investigate and compare the skin characteristics in Asian women. We evaluated values of skin physical parameters, and then assessed the correlations among the parameters, and regional differences in 1,500 Asian subjects in seven countries (Malaysia, Indonesia, Vietnam, Thailand, India, China, and South Korea). The values of transepidermal water loss (TEWL), pH, skin hydration, sebum content, skin sensitivity, elasticity, crow's feet wrinkles, and skin brightness were measured. New Delhi's women were observed to have a lower level of hydration in stratum corneum, sebum content, stinging scores, and darker skin color than others. Furthermore, their skin surface pH on all sites is the highest among seven countries. Vietnamese had the lowest pH values in skin surface. Korean and Chinese had generally higher elasticity and fewer wrinkles. Both the skin hydration and TEWL had positive correlations with the stinging test, and there was a negative correlation between wrinkles and stinging test. These results represent that there was no clear trend related to the area or region. Skin physical parameters should be studied along with understanding of regional differences and various factors (skin care habits, lifestyle and personal sensitivity).

  • In this study, we measured the anti-oxidative activity of Cirsium setidens and investigated its effect on UVA-induced MMP-1 expression in human dermal fibroblats. And then we examined possible improvement in skin elasticity by topical treatment with fomular including Cirsium setidens extract. The ethanol extract of C. setidens showed free anion radical scavenging effect(87.47 % at 1 mg/mL) and superoxide anion radical scavenging effect(61.71 % at 1 mg/mL) in the xanthine/xanthine oxidase system, respectively. At the concentration of 100 ${\mu}g/mL$, C. setidens extract showed 95.54% inhibition on lipid peroxidation of linoleic acid. UVA-induced MMP-1 expression in human dermal fibroblasts was reduced to 54.69 % by treatment with 100 ${\mu}g/mL$ of C. setidens extract. A human clinical study, in which oil-in-water emulsion with C. setidens extract was topically applied, showed significant increase in skin elasticity. These results suggest that the C. setidens extract can be effective anti-aging ingredient for cosmetics applications.
