  • Purpose : Wellness tourism is defined as travel for the purpose of promoting health and well-being through physical, psychological, or spiritual activities. The development and verification of a comprehensive wellness program for health care for workers is needed. The purpose of this study is to investigate the wellness and skin health effects of skin health programs in order to develop high-value health care services. Methods : The subjects were 15 middle-aged women who understood the research and volunteered and participated in the two-day skin health wellness program. Participants were measured to determine their wellness index and skin health twice: before and after participating in the program. Wellness index measures include comprehensive wellness, physical wellness, mental wellness, emotional wellness, social/cultural wellness, financial wellness, and environmental wellness. Skin health measurement items consisted of skin oil, skin water, skin pore, skin elasticity, skin wrinkle, and skin pigment. The skin wellness program included aerobic exercise, endurance exercise, functional food, cosmetics, herbal tea, massages, spa treatments, meditation, and marine leisure sports. The t-test analysis was used to compare the difference between wellness index and skin health measurement items before and after the program. Results : Among the wellness index items, the comprehensive wellness index (p<.05), mental wellness index (p<.05) and environmental wellness index (p<.05) showed statistically significant differences. Among skin health items, skin oil (p<.05), skin elasticity (p<.01) and skin wrinkle (p<.01) all showed statistically significant differences. There was no statistically significant difference in physical wellness, emotional wellness, social/cultural wellness, financial wellness, skin water, skin pore and skin pigment. Conclusion : This study confirmed that the two-day complex wellness program is an effective program for some items of wellness index and skin health.

  • The fairly recent standard of equipping mobile devices with advanced imaging sensors has opened the possibility of conveniently diagnosing skin conditions, anywhere, anytime. For this application, we attempted to estimate skin conditions from a skin image taken by a mobile handheld camera. To estimate the skin conditions, we specifically identified three skin features (pigmentation, pores, and roughness) that can be measured quantitatively from a skin image. The experimental data indicate that the existing thresholding methods are inappropriate for extracting the pigmentation and pore skin features. Thus, we propose a new line-fitting based thresholding method for skin feature detection. We thoroughly evaluated our proposed skin condition estimation method using our skin image database. The experimental results show that our proposed thresholding method can better determine the threshold leading to the most visually plausible detection, when compared to existing methods. We also confirmed that skin conditions can be feasibly estimated using a common mobile handheld camera (for example, a smartphone).

  • The skin permeation study has two meanings in cosmetics. One is how to promote the skin permeation of active meterials for improving their bioavailabilities and the other is how to decrease it of irritants for reducing their skin side effects. In this study, we selected methyl paraben, one of the preservatives, as a model irritant and tried to reduce the skin irritation by the decrease of skin permeation. Furthermore, the relationship between skin permeation and skin primary irritation was discussed. For in vitro skin permeation experiments, Franz type diffusion cells and the excised skin of female hairless mouse from 8 weeks old were used. The donor compartment was charged with oil only or O/W emulsion containing 0.3% MP. We selected 19 oils, including esters, triglycerides, plant oils, hydrocarbons, and alchols, which are broadly used in cosmetics. We evaluated with female guinea pig. The skin permeahility of MP from the oils showed following order: ester oils > triglycerides > plant oils > hydrocarbons > alcohols. We considered that this result was based on the different effect of each oil on the barrier function of stratum corneum. In O/W emulsion containing each oil, the skin permeability of MP decreased as the oil/water partition coefficient of MP increased. The skin primary irritation increased as the skin permeability of MP increased. In conclusion, we suggest that the skin irritation could be reduced by the decrease of skin permeability of MP, which may be obtained by the good selection of oils in cosmetic preparations.

  • In order to detect the skin color area from input images, many prior researches have divided an image into the pixels having a skin color and the other pixels. In a still image or videos, it is very difficult to exactly extract the skin pixels because lighting condition and makeup generate a various variations of skin color. In this thesis, we propose a method that improves its performance using hierarchical merging of 3D skin color model and context informations for the images having various difficulties. We first make 3D color histogram distributions using skin color pixels from many YCbCr color images and then divide the color space into 3 layers including skin color region(Skin), non-skin color region(Non-skin), skin color candidate region (Skinness). When we segment the skin color region from an image, skin color pixel and non-skin color pixels are determined to skin region and non-skin region respectively. If a pixel is belong to Skinness color region, the pixels are divided into skin region or non-skin region according to the context information of its neighbors. Our proposed method can help to efficiently segment the skin color regions from images having many distorted skin colors and similar skin colors.

  • Background: Kinetin is a plant hormone that regulates growth and differentiation. Keratinocytes, the basic building blocks of the epidermis, function in maintaining the skin barrier. Objective: We examined whether kinetin induces skin barrier functions in vitro and in vivo. Methods: To evaluate the efficacy of kinetin at the cellular level, expression of keratinocyte differentiation markers was assessed. Moreover, we examined the clinical efficacy of kinetin by evaluating skin moisture, transepidermal water loss (TEWL), and skin surface roughness in patients who used kinetin-containing cream. We performed quantitative real-time polymerase chain reaction to measure the expression of keratinocyte differentiation markers in HaCaT cells following treatment. A clinical trial was performed to assess skin moisture, TEWL, and evenness of skin texture in subjects who used kinetin-containing cream for 4 weeks. Results: Kinetin increased involucrin, and keratin 1 mRNA in HaCaT cells. Moreover, use of a kinetin-containing cream improved skin moisture and TEWL while decreasing roughness of skin texture. Conclusion: Kinetin induced the expression of keratinocyte differentiation markers, suggesting that it may affect differentiation to improve skin moisture content, TEWL, and other signs of skin aging. Therefore, kinetin is a potential new component for use in cosmetics as an anti-aging agent that improves the barrier function of skin.

  • The correct detection of skin color is an important preliminary process in fields of face detection and human motion analysis. It is generally performed by three steps: transforming the pixel color to a non-RGB color space, dropping the illuminance component of skin color, and classifying the pixels by the skin color distribution model. Skin detection depends on by various factors such as color space, presence of the illumination, skin modeling method. In this paper we propose a 3d skin color model that can segment pixels with several ethnic skin color from images with various illumination condition and complicated backgrounds. This proposed skin color model are formed with each components(Y, Cb, Cr) which transform pixel color to YCbCr color space. In order to segment the skin color of several ethnic groups together, we first create the skin color model of each ethnic group, and then merge the skin color model using its skin color probability. Further, proposed model makes several steps of skin color areas that can help to classify proper skin color areas using small training data.

The score distributions of skin health behavior were as follows; 8.7% of examniees got 20-40 points, 51.6% got 41-60 points, 36.7% got 61-80 points, 0.4% got 81-100 points. The maximum score was 100 points; the lowest score was 22 points and the highest score was 97 points, the average score was 56.9 points. 2. The general characters were as follows; the older subjects were and the higher subjects income levels were : the higher their scores of skin health behavior were. Scores of skin health behavior of students who temporarily stay out of school were higher than those who were enrolled full time. Scores of skin health behavior of university women attending women's universities were higher than those of university women attending co-educational universities. The greater subjects were satisfied with their appearances, the better their health states were, the more subjects were concerned about health problems, the higher their health states were, the more subjects were concerned about health problems, the higher their scores of skin health behavior were. 3. Characters related to skin were as follows; the better subjects skin conditions were, the higher their scores of skin health behavior were. Scores of skin health behavior of university women whose skin types were 'sensitive' were higher than those of university women whose skin was "not sensitive". Scores of skin health behavior of university women who worry about their skin wrinkles or skin color were higher than those of university women who have different kinds of skin troubles. Scores of skin health behavior of university women who get skin-relate information through dermatology clinics or beauty salonspecialists in this area were higher than those of university women who get the information through other sources. Scores of skin health behavior of university women who have experienced adverse effects of beauty products were higher than those of university women who have not experienced adverse effects of beauty products. 4. The relationships between variables related with skin health and skin health behavior were as follow; Skin states, health status and health concerns all had statistically significant correlation with skin health behavior.
