본 연구는 만 25세 이하의 여대생을 대상으로 스킨 도포 횟수에 따른 안면 피부의 수분함량 변화에 대한 연구를 하였다. 수분함량(moisture contents)은 피부 수분 측정기(피부 유수분측정기, PRC, 중국)를 이용하여 측 정하였다. 스킨은 I사의 블루베리 리밸런싱 스킨[대용량] 500ml를 임상실험재료로 사용하였다. 이마와 눈가, 볼, 턱 모두 도포 전 보다는 한 겹 도포 후가 수분함량이 더 높았으며, 한 겹 도포 후 보다는 열 겹 도포 후 수분함량이 더 높은 것을 알 수 있다. 이와 같은 결과로 세안 후 기초 제품을 도포할 때 가장 첫 번째 단계인 스킨의 횟수를 늘려 도포 한 후 로션과 수분크림 등 기초 제품을 바른다면 수분함량을 더욱 높일 수 있는 방법이다.

In this study, the moisture content of the face skin was changed according to the number of skin applications for female college students under 25 years of age. Moisture contents were measured using a skin moisture meter (skin oil and moisture meter, PRC, China). Skin used 500ml of Innisfree's blueberry rebalancing skin as a clinical trial material. Both the forehead, eyes, cheeks, and chin had a higher moisture content after one layer of application than before and after one layer of application, and after ten layers of application, it can be seen that the moisture content is higher. As a result, when applying basic products after washing your face, the first step is to increase the number of skins, and then apply basic products such as lotion and moisturizing cream to increase the moisture content.

When it comes to a skin treatment, most people usually apply a massage or a familiar type of pack onto the skin while some of them want to receive a special skin treatment program at a skin care shop. People tend to think of getting such skin treatments above only when they see some troubles on the skin which they would consider serious. People feel bad to see enlarged pores and rough skin due caused by a lack of moisture. The skin of such conditions did not take any make-up and wrinkles are increased as the skin does not feel relaxed and moist. People seem to be aware of positive effects of three skin treatments which are massage, a pack and some special skin treatment and yet, not a single study has been conducted to actually prove the effects of the skin treatments. Since how those treatments would work together has not been investigated so far, the author of this study conducted a research on the matter targeting an experimental group which was later given three different experimental assignments. According to the results, the massage, Vitamin C and the rubber pack applied with a skin counseling system device appeared to have multiple reactions to each other and this has improved the moisture level of the experimental group as decreasing the pores and the wrinkles. The group with the rubber pack was particularly determined to have a great change with the pores, and the massage and Vitamin C were found less effective for the pores. For the wrinkles, the study figured out that the massage and the pack would not come up with promising results only by themselves.

To examine the effect of a program to encourage fluid intake in institutionalized elderly people. A non-equivalent control group pre- and post-time series design was used. Data were analyzed with the SPSS program by t-test, chi-square test, and repeated measures ANOVA. Elderly people in the experimental group showed significantly better outcomes in terms of body weight reduction, skin moisture levels, and fluid intake and output compared with elderly people in the control group. Elderly people in the experimental group also showed significantly better outcomes in comparison with elderly people in the control group in relation to urinalysis including odor, pH, specific gravity, osmolality, color, white blood cell count, and bacteriuria. A hydration management program could be one of the most effective nursing strategies to ultimately enhance the quality of life and health of institutionalized elderly people.

A glycolic acid peel is the typical one of chemical peels used to improve and smooth the texture of the facial skin using a chemical solution such as natural fruit acids. Glycolic acid is one of alpha hydroxy acids(AHAs) to remove old, dead, and sun-damaged surface skin cells, and promote healthier and softer skin. This study was conducted to evaluation the improvement effects in skin moisture, sebum(oiliness) and elasticity for dry and oily skin types after glycolic acid treatment. The 20 young ladies of 21.0±5.2 years old were assigned to two group according to their dry or oily skin types. And then skin moisture, sebum and elasticity in T-zone(forehead) and U-zone(cheek) using a non-invasive measuring method were measured after a glycolic acid peel treatment a week for 4 weeks. The results were as follows： 1. The sebum content of T- and U-zone in dry skin group showed a significant increase with increasing glycolic acid peel treatments, while in oily skin group it was significantly decreased (p<0.05). 2. The moisture content of T- and U-zone in dry skin and of U-zone in oily skin group was increased with increasing glycolic acid peel treatments. But the moisture content of T-zone did not show significant difference according to repeated chemical peel treatments (p>0.05). 3. The elasticity content of T-zone and U-zone in dry skin group and of T-zone in oily skin group was significantly increased according to repeated chemical peel treatments. But the elasticity content of U-zone in oily skin group did not show according to repeated chemical peel treatments (p>0.05).

본 연구는 비침습적 방법을 이용하여 유아기, 아동기, 청소년기의 피부상태를 측정하였다. 성장시기에 따른 피부표면의 수분, 탄력, 거칠기 측정값 간에 상관관계를 확인하였으며, 피부표면은 아라모티에스(ARAMO-TS) 기기를 이용하여 평균기온 27.57±3.19℃, 상대습도 39.27±10.82%의 실내에서 측정하였다. 수분값의 측정은 동일 세안제로 세안하고 1시간 안정 후 이마 중앙, 눈 밑, 볼 중앙부위를 차례로 측정하였고, 탄력값과 거칠기 측정은 양쪽 볼 중앙과 양쪽 눈 밑을 측정하였다. 측정 결과 남자가 여자에 비해 수분값과 탄력값이 높았으며, 그 중 수분값에서는 청소년기, 유아기, 아동기 순으로 감소하였고(p<0.001), 탄력 값에서는 청소년기, 아동기, 유아기 순으로 감소하는 경향을 확인할 수 있었다(p<0.001). 피부표면의 거칠기 값은 아동기, 유아기, 청소년기 순으로 감소하였고(p<0.001), 연령과 성별에 따른 수분과 탄력값에서 유의한 상관성을 보였으나 거칠기 값에서는 상관성이 없는 것으로 나타났다. 따라서 본 연구는 유아기, 아동기, 청소년기를 대상으로 성장시기에 따른 화장품 및 피부 관리 프로그램 개발에 유용한 기초 자료로 활용될 수 있다고 판단된다.

In this study, we compared the skin condition of young people in a babyhood, childhood, and adolescent period using a non-invasive method. The conditions to compare the skin of the young people include moisture, roughness, and elasticity. The skin measurement was performed using an ARAMO-TS instrument in a room at 27.57±3.19℃, under 39.27±10.82%% of relative humidity. After face washing with a cleansing foam, the moisture was evaluated at the center of the forehead and the cheeks, and the below eyes, respectively. The elasticity and roughness data were obtained from the center of the cheeks and the below eyes, respectively. The skin moisture and elasticity of the man were more excellent than those of the woman (p<0.01). The skin moisture value decreased in the order of adolescent period, babyhood, and childhood. As older from an infant to an adolescent, the elasticity was better (p<0.01). Moreover, the surface of the skin was more smooth in order of an adolescent period, babyhood, and childhood (p<0.01). The moisture and elasticity showed the correlation between the age and sex. In contrast, there was no the correlation for the skin roughness. In conclusion, we anticipate that these results can be extensively used as a basic information to develop cosmetics and skin care programs for the growing people.

The purpose of this study is to estimate about emollient effect of avocado oil on human heels and elbows which are in dry condition. The number of study participants were 34, including 16 study group and 18 control group. The study was performed under nonequivalent control-group pretest quasi experimental research design. The subjects in study group applied avocado oil mist on their heels and elbows twice a day in the morning and evening for 7 days. The ones in control group applied the mist without avocado oil in same methods. After completion of experiment, the emollient effect of avocado oil was estimated by the moisture measuring instrument in both groups. There is significant emollient effect of avocado oil on elbows but non- significant on heels. The subjects felt moisture and emollient sense on their elbows and heels themselves. Conclusively, the emollient effect of avocado oil was different in quantity between the elbows and heels. Because heels is thicker and drier than elbow, much longer application of avocado oil and supportive method such as scrubbing is required to get emollient effect on heels.

The purpose of this study is to examine the effect of oils derived from natural plants such as red ginseng, jojoba, avocado on skin of female group with poor healthy conditions. The mist containing oils from natural plants were treated to the 48 female with old and poor healthy conditions in 3 hospitals at C, K and P cities. The subjects were divided into 4 groups; control(10 individuals), red-ginseng oil(16 individuals), jojoba oil (13 individuals), and avocado oil(9 individuals) treated-groups. Before experiment, survey a questionnaire and measurement of moisture level on target skin were made. Mists contained 3 types of oil and 1 type of oil free were applied to same skin areas, both elbows and heels, at 2 times, in the morning and evening for 2 weeks. Only the moisture level on target skin areas was measured at day 7 after experiment. However, survey of a questionnaire about satisfaction was made after use of oil contained mists and moisture level of same skin areas was measured together at day 14 after experiment. The results showed that the moisture level of both elbows got significant increase statistically at 1 week later of experiment, but it had same result on both heels at 2 weeks later. After experiment, the level of satisfaction on their own skin was statistically significant increased about improvement of dry skin, being functionality, and helping on skin troubles. Conclusively oils derived from natural plants had improving effect on dry skin. Further, study would be considered with old women in healthy conditions.

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).

Recently, there has been a strong demand for healthy skin and good looking. However, the incorrect perception of skin conditions can cause side effects at selection of cosmetics and during skin management. Therefore, this study has measured and analyzed skin conditions (sebum, moisture, pH, melanin and erythema) by the perceived sebum and moisture conditions on the face against college women. According to analysis on perceived sebum and skin conditions, there was difference between a group with more-than-average sebum contents and a group with a lack of sebum in terms of sebum levels. In the forehead and around the eyes, the sebum level was high in the group with more-than-average sebum contents. According to skin analysis by the perceived moisture level, melanin was significantly high in a group with more-than-average moisture in the chin only. In case of skin analysis values, no significant difference was found between the two groups in which moisture was perceived. Therefore, it’s been confirmed that there is no difference in skin conditions by the facial region. Even though the perception of sebum conditions was matched with sebum levels, the perception of moisture conditions was not matched with skin conditions. Therefore, it appears that it is necessary to select cosmetics and manage skin through scientific analysis instead of depending on the subjective perception of skin conditions.
