Purpose: The purpose of this study was to verify the correlation analysis between fluid intake on skin hydration and pH of college students. Methods: The subjects were 129 female nursing students in D city. Data were collected by a self-administered questionnaire, using a skin moisture checker and skin pH meter on faces, hands, and feet. The collected data were analyzed by descriptive statistics, t-test, ANOVA, and Pearson correlation analysis, using SPSS WIN, 20. Results: The daily fluid intake was composed of 57% pure water, 21% caffeinated beverages, 22% non-caffeinated beverages. There were significant differences in average skin hydration on the three body parts according to pure water, caffeinated beverages, and non-caffeinated beverages; however, there was no significant difference measured by fluid intake. There was a significant positive correlation between fluid intake and skin hydration: between pure water and skin hydration. There was significant negative correlation between caffeinated beverages and skin hydration: between non-caffeinated beverages and skin hydration. Conclusion: The results suggest that fluid intake, pure water, caffeinated beverages, and non-caffeinated beverages have an effect on skin hydration and pH. Therefore, it is good to increase the amount of fluid intake but, it is recommended to increase the amount of intake of pure water rather than beverages to improve skin status.

피부질환에는 보조 치료로 다양한 치료용 샴푸가 빈번하게 적용되고 있으나 이들 샴푸의 피부수분에 미치는 영향은 일반적으로 평가되지 않고 있는 실정이다. 따라서 치료용 샴푸의 정확한 처방을 위해서는 피부의 수분을 측정하기 위한 측정법이 필요하다. 본 연구는 여러 종류의 치료용 샴푸의 피부 수분에 대한 영향을 알아보기 위해 Corneometer를 이용하여 피부에 샴푸를 적용후 수분을 측정하였다. 5두의 건강한 개를 대상으로 7가지 샴푸로 Humilac, Sebocalm, Sebolytics, Etiderm, Benzoyl peroxide, HyLyt, Zn-7 Derm를 선정하여 적용하였다. Humilac의 경우 통계학적으로 유의한 피부수분의 증가는 적용 후 17분(p<0.05), 77분(p<0.01)에 나타났으며, Benzoyl peroxide의 경우 적용 후 77분(p<0.05)에 피부의 수분이 유의하게 감소되었다. 다른 샴푸의 경우 통계학적으로 유의하지 않았으나 전반적으로 감소하는 경향을 보였으며 적용 후 77분에 최초 적용 수치에 근접하게 감소하였다. 어떤 샴푸도 피부에 부작용을 유발하지 않았다. Corneometer는 실제 임상에서 피부의 수분을 평가하는데 간단하고 유용한 측정방법을 사료된다.

We have produced, characterized and compared different colloidal vehicles based on nanoemulsions. We also have investigated morphology and droplet distribution by means of electron microscope and photon correlation spectroscopy. Nanoemulsion systems characterized by different method on formulations have been obtained. Hydration power has been studied by means of a corneometer, measuring the skin electrical capacitance before and after the application of various type of skin lotions. It has been demonstrated that nanoemulsion with oil or fatty alcohol displayed a pronounced hydration power with respect to the solubilization system. In order to compare the smoothness of the skin after using skin lotion, we have measured the friction force. The skin lotions produced by nanoemulsion technique show improved smoothness of an atopic skin.

This study was performed to analyze the relationship among sebum hydration content of the skin and nutritional intake, serum antioxidant minerals and antioxidant enzymes, and lipid peroxide concentration in 50 female subjects in their 20s. The skin type was divided into Dry Skin, Mixed Skin, and Oily Skin, and the dry skin group was 14%, the mixed skin group was 56%, and the oily skin group was 30% of all subjects. The average age of the subjects was $20.54{\pm}1.43$ years and BMI was 20.66. The average sebum content in each group was in the order of T-zone>forehead>chin>cheek. In case of the T-zone, a significant difference between the dry skin group and the oily skin group was observed, suggesting that the area is most sensitive to sebum content by skin type. Significant differences were not observed in energy and nutrient intakes by skin type. Serum concentrations of antioxidant minerals such as copper, manganese, zinc and selenium were not significantly different among the groups, but the dry skin group tended to be higher than the oily skin group. Serum catalase was significantly higher in the oily skin group (P < 0.05), and MDA was significantly higher in the mixed skin group (P < 0.05). The hydration of the cheek and serum zinc showed a negative correlation, and the sebum content of the cheek and GPx showed a significant negative correlation. The hydration of the forehead and serum copper showed a significant negative correlation, and the hydration of the forehead and GPx showed a significant positive correlation. The hydration of the chin and serum SOD showed a significant positive correlation. With these results, it is considered that the basic condition of nutritional status can affect the skin health.

Purpose: The purpose of this study was to examine the effects of aroma massage on pruritus, skin pH, skin hydration and sleep in elders in long-term care hospitals. Methods: The participants were elders over 65 years old admitted to long-term care. They were assigned to the experimental group (26) or control group (28). Data were collected from May to August, 2012. Visual Analogue Scale and Verran and Snyder-Halpern Sleep scale were used to identify levels of pruritus and sleep. A skin-pH meter and moisture checker were used to measure skin pH and skin hydration. Aroma massage was performed three times a week for 4 weeks for elders in the experimental group. The data were analyzed using the SPSS Win 17.0 program. Results: There were significant differences in pruritus, skin pH and skin hydration between the two groups. However there was no significant difference in sleep. Conclusion: The results indicate that aroma massage is effective in reducing pruritus, skin pH and increasing skin hydration in elders. Therefore, this intervention can be utilized in clinical practice as an effective nursing intervention to reduce pruritus in elders in long-term care hospitals.

Purpose: The study was conducted to investigate the skin hydration level in various body sites and identify the influencing factors in neonates. Methods: An exploratory comparison study was designed to measure the stratum corneum hydration, using a National DM-R2 on the forehead, abdomen, buttocks, and the back of the hands and feet of 198 neonates including 92 premature infants. Results: The results showed 32.7%-36.5% of stratum corneum hydration for all sites. Premature infants revealed a higher hydration level on the peripheral sites (dorsal hand and feet) than those of the full-term infants, possibly resulting from therapeutic regimens including an incubator or radiant warmer. Infants in an incubator showed a higher hydration level than those in radiant warmers, suggesting more attention to fluid management for infants in the open environment. In addition, all stratum corneum hydration measurements except one, from the forehead, showed a positive correlation with postnatal age in full-term infants while showing no relation to any measurements in premature infants. Conclusion: The study demonstrated the very low skin hydration levels in hospitalized neonates, particularly in premature neonates with more susceptible skin hydration instability despite therapeutic interventions for fluid balance. More vigilant fluid management is imperative in neonates, particularly those in the open environment.

This study investigated the effects of wearing latex gloves with inner gloves on the skin hydration of the hands. Fifteen young males participated in the following three conditions: bare hand (BH), latex glove (LG), and latex glove with inner glove condition (LGIG) at an air temperature of $28^{\circ}C$ with 50%RH. Subjects typed a book for 120 min. The results were as follows. Skin hydration was greater for LG and LGIG than BH (p<.001), but no difference was found between LG and LGIG. Skin hydration showed greater values on the thenar and dorsum compared to the palm for both LG and LGIG (p<.05). Skin hydration on the thenar increased during the typing for LG and LGIG, but on the dorsum, palm and finger maintained after 40 min typing. There were positive relationships between hand skin hydration and hand temperature (p<.05). Subjects indicated 'much warmer' and 'more humid' for the LG and LGIG compared to the BH (p<.001), but no differences were found between LG and LGIG. In conclusion, wearing inner gloves inside latex gloves did not induce a reduction of skin hydration and hand temperature; however, significant differences were found in all measurements between bare hands and gloved hands.

피부의 최외곽층인 각질층에 대한 수분량을 측정하는 것은 피부장벽기능과 생물리학적 특성에 대한 피부 건강함, 유연함, 부드러움 등의 중요한 정보를 제공한다. 그러나, 평가자와 피험자와의 개인적인 차이와 측정환경의 변화에 따라 재현성과 반복성에 있어서 각질층의 수분량을 측정하는 데에는 많은 어려움이 있다. 본 연구의 목적은 피부 각질층에 여러 종류의 제품을 사용 전후에 객관적으로 수분량을 측정하는 데에 있다. 40명의 건강한 자발적 피험자의 하박 내측을 피부의 전기용량 특성을 이용하여 수화정도를 측정하였다. 피부 수분량은 시험제품 도포 후, 3 h, 6 h 뒤에 측정하였다. 무도포 부위의 편차를 보정하기 위해 수분증가율을 이용하였고, 5반복 측정을 통하여 분석하였다. 수분량 측정에 가장 효과를 보이는 대표적 폴리올 종류인 글리세롤과 부틸렌 글라이콜을 이용하여 연구를 수행하였다. 대부분의 폴리올 종류는 피부 수분량 변화에 영향을 미치기 때문에 연구에 참여한 피험자에게 0 ~ 20%의 글리세롤을 표준제품으로 사용하여 보정하였다. 피부 수분량은 낮은 농도의 글리세롤 범위에서 직선의 상관관계를 갖기 때문에, 글리세롤의 농도에 따라 피부 수분량에 대한 피험자 각각의 표준화된 곡선을 얻었다. 이렇게 얻어진 피부 수분량에 대응하는 글리세롤 농도 값은 통계학적으로 재현성과 반복성을 보였다. 게다가 이렇게 얻어진 표준화 곡선은 피험자 개인의 피부특성으로 활용할 수 있었다. 이러한 연구 결과는 화장품과 같은 피부외용제품에 대한 미세한 피부 상태의 변화와 외부환경 변화에도 불구하고, 같은 결과를 보였다. 향후 이러한 결과를 토대로, 계면활성제와 지질, 수용성 물질에 대한 제품 원료에 대한 피부 측정에 필요한 비침습적 방법과 병행해서 사용할 수 있을 것으로 사료된다.
