Purpose: The purpose of this study is to show that Meibometer® is a useful analysis technique for the measurement and evaluation of the sebum content on the scalp by comparing the test analysis results of the scalp sebum content using Meibometer® and Sebumeter®. Methods: In this study, Meibometer® and Sebumeter® were used for quantitative measurements of the sebum content on the scalp of the test volunteers, and the measurement results were analyzed using the paired t-test and Pearson’s correlation coefficient. Results: The scalp sebum content was analyzed using Meibometer® and Sebumeter®, and according to the results, both measuring devices exhibited a reduction in the scalp sebum content, compared to before the testing product was applied (p <0.001). The Meibometer® and Sebumeter® measurements showed a significant positive correlation (r=0.411) in the second measurement. Conclusion: These results showed that the measuring results of both Meibometer® and Sebumeter® had a high correlation and they were appropriate for measurement. However, it is suggested that for reducing the interference of the adjacent hair with sebum and quantitatively evaluating the sebum content on the scalp only, Meibometer® can be a relatively useful analysis technique, and it is expected that further test analysis and studies using Meibometer® will be actively conducted in the future.

目的: 通过比较使用Meibometer®和Sebumeter®两种仪器对头皮皮脂含量的测试分析结果，表明Meibometer® 是一种有用的分析技术，可用于测量和评估头皮上的皮脂含量。方法: 本研究使用Meibometer®和Sebumeter® 对测试志愿者头皮上的皮脂含量进行定量测量，并使用配对t检验和Pearson相关系数对测量结果进行分析。结 果: 使用 Meibometer®和Sebumeter®分析头皮皮脂含量，根据结果，与使用测试产品前相比，两种测量设备 的头皮皮脂含量均有所降低(p <0.001）。Meibometer®和Sebumeter®测量结果在第二次测量中显示出显着的 正相关(r=0.411)。结论: 这些结果表明Meibometer®和Sebumeter®的测量结果具有高度相关性，适合测量。但 是，建议为了减少相邻头发对皮脂的干扰，仅定量评估头皮上的皮脂含量，Meibometer®可能是一种相对有用 的分析技术，预计使用Meibometer®进行进一步的测试分析和研究今后将积极开展。

This study is intended to look into how effective cosmetics containing 1.5% allantoin and 5% calendula extracts could be in relieving facial porphyrin sebum. To achieve this, a randomized double study was conducted on 16 21-year-old women living in Seoul and Gyeonggi area through January 16 to February 29, 2016. They were divided into a control group (allantoin- and calendula extracts-free) of 8 women, and a allantoin- and calendula extracts group (containing 1.5% allantoin and 5% calendula extracts) of 8 women. The control group, allantoin- and calendula extracts group spent 3 hours at a time to apply each group's toner and cream, and continued for 3 hours after applying the distributed make-up base and grease paint foundation to adhere to their face. They washed their face with cleansing cream provided after 3-hour make-up, and then their facial skin was measured after 20 minutes. The results were as follows. The use of grease paint foundation for 3 hours at a time showed that the control group has a tendency towards a decrease in normal sebum, porphyrin sebum. The moisture content decreased (p<.05). The 1.5% allantoin and 5% calendula group has a tendency towards a decrease in normal sebum. The porphyrin sebum content decreased (p<.05). The moisture content tended to increase. As for the findings stated above, cosmetics containing 1.5% allantoin and 5% calendula extracts help you relieve the skin irritation of stage make-up. Consequently, they reduce porphyrin effectively. Especially, as the oxidized sebum, porphyrin is one of factors that cause trouble by stage make-up, the use of cosmetics suitable for the skin type to reduce porphyrin effectively can minimize facial skin irritation of many people who make-up.

This study is about our effort to find and figure out the improvement of acne symptom and antibiotic effect after applying nutrient liquid of stem cell to the people of having acne. Our study was implemented by the experiment to determine the superiority between before and after the self-control. In the methodology of designation of comparison groups, there appears the apparent difference between the patients by the age, constitution, life style and the degree of symptom of acne and this brings inevitably a big influence to the homogeneity between groups. Thus, we decided to execute our study by selecting the patients who took the medical treatment to control such differences. The number of patient was 15 as those whose conditions are proper to the purpose of our study and in random base, we compared the faces of each individual as of the clinic object, regarding and taking one side of their faces for comparing and the other side of their faces for experiment. The experiment period was for 6 weeks and the experiment was practiced 1 time in a week. We measured and counted the quantity of secretion of Sebum, skin P, number of acne, number of virus permanently staying on skin before the experiment, after the experiment, 2 weeks after the experiment, 4 weeks after the experiment and 6 weeks after the experiment. On the area of experiment, we put the needle by using tiny needle on the center of acne and daubed this area with 10% of the culture fluid of stem cell 2 times in a day in the morning and in the evening, and we practiced the acne treatment 1 time in a week for 6 weeks. During the period of our experiment, we used the same home-care product on the comparison area and experiment area. According to our study, in respect of improvement of acne symptom, it turned out as the quantity of secretion of Sebum is remarkably dropped on the cheek 1(p=.0079), cheek 2(p=.0041), forehead 2(p=.0007), chin 1(p=.0001) and chin 2 ( p=.0021). It also showed a dropping on the area of nose(p=.0521) and forehead 1(p=.0651) but it did not show a statistical change. In the change of the number of P. acne, the statistical change appeared on the area of experiment such as nose(p=.0163), forehead 1(p=.0477) and chin 2(p=.0013) and the number was reduced on the areas of cheek 1, cheek 2, forehead 1 and chin 1 but it did not show a notable change. In general, in the area of comparison, the number of acne was not remarkably reduced in all areas of comparison. As we explained here above, in our experiment we applied the program of improving acne symptom by utilizing the culture fluid of stem cell and we could find this is effective to the improvement of acne symptom and anti-biotic effect. Our try for improvement of acne symptom by applying the culture fluid of stem cell has the meaning that this study proved the effect of the culture fluid of stem cell as we approached in respect of the contents of acne, and we hope the result of our study shall be utilized in parallel with existing medical treatment.

The present study aimed to find out the effects of different approaches of Swedish massage on sebum, moisture and facial skin condition changes in 24 middle-aged women (back and face massage group: 12, back massage group: 12). For the purpose of analyzing differences between groups and depending on timing, the paired t-test was used. To sum up, the analysis found the following. In terms of the changes in the sebum U-zone, the sebum decreased by 49.09% in the back and face massage group, whilst it increased by 76.53% in the back massage group after the massage treatment. In the sebum T zone, the sebum decreased by 9.89% in the back and face massage group whereas it increased by 19.84% in the back massage group after the massage treatment. There were differences in mean values in both groups after the massage treatment for the sebum U-zone and T-zone with no statistical significance (p>.05). As for the changes in the moisture U zone, the moisture increased by 2.47% in the back and face massage group after the massage treatment with no statistical significance (p>.05), whereas it increased by 6.07% in the back massage group, which was statistically significant. The moisture in the moisture T- zone increased by 2.64% in the back and face massage group after the massage treatment, which was not statistically significant (p<.05), whereas it increased by 10.17% in the back massage group, which was statistically significant. In respect of changes in skin condition after the massage treatment, the back and face massage group showed decreases in hair follicles (2.45%), roughness (42.37%), keratin (52.48%), wrinkles (0.92%), pigmentation (25.06%) and skin elasticity (12.87%). Notably, nothing but changes in roughness and pigmentation was statistically significant (p<.05). In the back massage group, the massage treatment decreased hair follicles (1.12%), roughness (12.68%), keratin (52.70%), wrinkles (3.37%) and pigmentation (16.23%), while increasing the skin elasticity by 12.64%, which was not statistically significant (p>.05).

In this study, we evaluated the effects of essence-formed cosmetic ingredients containing the galactomyces ferment filtrate on human skin improvements in keratinization, pores, sebum excretion, brightness and acne. For analyzing the effects, twenty volunteers were participated and each results was determined by treating the essence containing 97% of galactomyces ferment filtrate on their faces in three times. The results showed that the number of the large opened pores and blackhead pores on faces were significantly reduced more than 15.66 and 21.84% by treating the essence as compared to the number of pores on untreated control faces. Also the amount of sebum and keratin in faces were meaningfully reduced by 64.17 and 16.47%, respectively. In addition, we further demonstrated that the levels of the skin brightness were improved after treatment of the reagent by 2.49% respectively. Moreover, the number of acne were decreased 9.59%. Survey analysis showed that the volunteers had highly satisfaction on the reagents. Collectively, the results indicated that the 97% of galactomyces containing essence-formed cosmetics have an improved effect on facial skin.

This study aimed to understand how a shampoo and a mist personally designed by the study would affect the conditions of the seborrheic oily scalp. In order to observe any positive change in the scalp, the study measured both the conditions and the oil-moisture level of the scalp. The study expected that the participants in the clinical test will help it to know how the shampoo and the mist would improve the conditions of the scalps, which was, in other words, the benefits of the two scalp improvement agents. Regarding the research methods, the study applied the scalp improvement shampoo and Q31 (a mist for the oily scalp) that the study had personally created to these five research participants who have been suffering from the oily scalp. In terms of the measuring process, using Digital Scope, the study looked into how the scalp had improved and in order to measure the rate of change in terms of the oil-moisture level, the study used on COSMOMED (Germany), Sebumeter. According to the findings from the investigation, the amount of moisture improved while the oiliness significantly decreased. The study also learned that how efficiently the scalp had been exfoliated. In addition, it appeared that the scalp improvement agents remove impurities around the pores. In the light of what has been learned so far, the study confirmed that both the shampoo and the mist for the oil scalp invented by the study make positive changes in the conditions of the scalp.

This research is intended to clarify influence of the produced scalp improving agent on seborrheic or dry scalp. For achieving this intention, there was implementation to measure the scalp condition, oil·moisture status. Effect as a product of the scalp improving agent was explored through improvement effect on clinical subjects was examined. As for research method, we spreaded the scalp improving shampoo and Q33 (mist for dry skin) on 5 subjects whose scalp were dry type. As for measurement tools, we did apply the Digital Scope, which allowed the examination to be conducted under magnification radiography of 300 times, into investigating improvement situation on scalp, and apply the COSMOMED (Germany), Sebumeter into measuring moisture variation rate on scalp. Taking a close look at the research result, there could be found to be significant reduction of oil, alleviation of dead skin cell, washing around pore. It could be regarded as evidences of "cleaning effect". As confirmed by the result, it proves that the produced scalp improving agent and mist for dry skin have improvement effect on scalp.

It is a comparative research on scalp condition of the middle-aged women in 40~50’s according to intake of red ginseng which was famous for enhancement of immunity level, anti-oxidative activity, promotion of blood circulation. The experimental groups are total 44 women objects in 40-50’s which is divided into each intake group of 3g/day of red ginseng, and 6g/day of red ginseng. It was observed the change of sebum output, microbial quantity, keratin quantity, pH of scalp for 12 weeks. the microbial quantity was resulted that Cont. group increased 0.6% G3 group decreased 15.56%, and G6 group decreased 16.61% and then the keratin quantity was resulted that Cont. group decreased 0.27%, G3 group decreased 70.12%, and G6 group decreased 76.94% before and after the experiment. And the sebum output was resulted that Cont. group decreased 0.27%, G3 group decreased 70.12%, and G6 group decreased 76.94% and the pH was resulted that Cont. group increased 0.001%, G3 and G6 group decreased 0.002% before and after the experiment, these showed no significant difference.

This study has attempted to investigate changes in skin conditions (sebum, moisture and elasticity levels) aftergiving a skincare lesson to 10 elderly women 6 times in total for two (2) weeks and having them take care of their skin on their own twice a week for eight (8) weeks and find out how their self-Respect and life satisfaction have changed. In terms of analysis of skin conditions, Hydration (Corneometer, CM825), sebum (Sebumeter, SM815) and elasticity (Cutometer) were measured using the multi-process of MPA9 (C+K electronic GmbH, Cologne, Germany). Using a questionnaire tool, self-Respect and life satisfaction were examined. Then, the following results were obtained: The Hydration, sebum and elasticity levels increased in four (4) and eight (8) weeks after self skincare, but no statistical significance was observed. In terms of self- Respect and life satisfaction, self-Respect increased from 31.90± 3.44 to 36.20±4.07 while life satisfaction increased from 66.80±8.71 to 71.10±7.49 in eight (8) weeks (p<.001).

It is a comparative research on facial skin condition of women in 30’ s according to intake of red ginseng which was famous for enhancement of immunity level, anti-oxidative activity, promotion of blood circulation. The experimental groups are total 21 women objects in 30’s which is divided into 7 persons for each intake group of 3 g of red ginseng, and 6 g of red ginseng, and they intake the daily amount of red ginseng in the morning before having breakfast once a day. It was observed the change of sebum, moisture, melanin, erythema, and skin color of each part such as forehead, left eye, right eye, left cheek, right cheek, and chin for 12 weeks. When observed the change of skin condition by averaged each part in face, since the sebum was resulted that G3 group increased 45% compared to Cont. group, and G6 group increased 51% compared to Cont. group, the difference between experimental groups are not significant. The moisture was resulted that G3 group increased 9% compared to Cont. group, and G6 group increased 13% compared to Cont. group, and then G3 group showed effect of second-thirds of moisture increase of G6 group. Also, melanin index change was resulted that G3 group decreased 11% compared to Cont. group, and G6 group decreased 13% compared to Cont. group, and then the difference between experiment groups was not significant. Erythema index change was resulted that G3 group inhibited 6% compared to Cont. group, and G6 group inhibited 9% compared to Cont. group, and then G3 group showed the effect of second- thirds level of erythema generation inhibition of G6 group. Like this, while it is indicated that red ginseng intake changed to measurement value of face skin positively, the increase of sebum and melanin generation inhibition was more economical in 3 g intake, and increase of moisture and erythema generation inhibition was indicated that 3 g intake effected of second-thirds compared to 6 g intake.

In this study, the effect of Semen cuscutae Extracts on the acne of 20’s students were studied. 18 Volunteers were selected twenties age group on acne skin. Toner, essence and pack which were made with or without of Semen cuscutae Extracts were applied to their faces. Also instructions were provided three times to them for the self skin care (face cleansing, moisturizing, and protection) through the survey and skin measurement. Clinical tests were conducted a total of 12 times for the duration of six weeks. Based on the korean acne grading system, skin microorganism, skin keratin, sebum contents, erythema index and melanin index, all factors were measured before the test, after three weeks and six weeks after the test. The control group not treated with Semen cuscutae did not show any statistically significant difference after six weeks, while the group treated with Semen cuscutae showed statistically significant difference. In addition, there was a significant improvement in acne skin in both objective and subjective parameters after treatment with Semen cuscutae group compared with control group.
