Skin type is generally classified by lipid moisture content of skin, and health condition of skin is highly affected by individual living conditions. Hence, this study tried to check the facial lipid moisture values of male and female high school students with using non-invasive skin bioengineering, and also tried to understand the relationship between the subjective lipid moisture condition and skin problem. As a result, a case that the subjects take cognizance of being enough about all the subjective lipid moisture condition takes high rates as 71 people(39.9%), 56 people(31.5%). Futhermore, as subjective skin problems, acne is the highest problem for 152 people(85.4%), and in order of rates, there are the sensitive, wrinkle, pigmentation, and telangiectasis. According to the non-invasive method, the facial lipid value is measured as 41.54±28.56 ㎍/㎠ at the forehead, and the moisture value is measured as 61.29±13.97 ㎍/㎠at the forehead. Therefore, the study show that the value at the forehead is higher than at the cheek in the objective facial lipid moisture condition. According to the sex, the subjective facial lipid condition of the male students is higher than of the female students in the subjective skin condition. In addition, while, in case of subjective skin problem, female students complain about their extension of the capillary vessel and their sensitivity more than the male students, in case of wrinkle, male students complain more than female students. In the relationship between the lipid moisture measurement according to the sex, the lipid value in the male`s cheek takes 37.24±26.05 ㎍/㎠and the moisture value in the male`s forehead takes 63.15±15.11 AU, and both of the results are higher than the female students. Hence, the study shows that secretion of the sebum and the degree of moisture content is different between the male and the female students.

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.

Tea Tree Essential Oil이 피부상태에 미치는 영향에 관한 연구 -청소년피부를 중심으로-

김보람 ( Bo Ram Kim ),윤천성 ( Chun Sung Youn ) 한국미용학회 2008 한국미용학회지 Vol.14 No.3

With the standard of living being elevated, people have an increasing interest in health and beauty. In particular, natural and eco-friendly beauty products, rather than products made of artificial chemicals, are gaining popularity as ways to enhance people`s skin conditions. In this regard, this paper studies the effect of Tea Tree essential oil, one of the natural products in the limelight, and also considers the oil`s potential to be used as natural antibiotics. The subject of this study is a group of 58 male and female middle school students in Daejeon and the group is divided into two groups of 29. The sample group is given cosmetics containing Tee Tree essential oil and the control group is given cosmetics without it. All of them are required to apply the cosmetics twice a day, once in the morning and once in the evening, for 4 weeks. The skin conditions of the two groups are measured by cornemeter, sebumeter and skin pH meter three times from the beginning of the test at two-week intervals over the four weeks` test period for comparison. The followings are the results that this study presents. The first hypothesis that “Tea Tree essential oil will have a positive effect on the level of moisture within the skin.” was denied. Skin condition is highly influenced by seasonal change. And as the study was conducted during the seasonal transition from late summer to autumn, reduction in skin`s moisture was detected in all subjects regardless of which group they belong to. The dry weather also caused dry skin making it difficult for us to precisely grasp how effective Tea Tree essential oil was on the subjects` skin. The second hypothesis that “Tea Tree essential oil will have a positive effect on the level of oil within the skin.” was supported. Tea Tree essential oil was found to balance the level of oil within skin by helping reduce oil in an excessively oily skin and by providing and maintaining a certain degree of oil in an oil-deprived dry skin. In short, Tea Tree essential oil has proved to have a certain function as a sebum controller. The third hypothesis that “Tea Tree essential oil will have a positive effect on the changes in skin pH.” was denied. Since not only the sample group but also the control group showed some changes in their skin pH levels, there was no evidence that Tea Tree essential oil had a direct impact on the pH level changes. Since it proves to improve the oil balance within people`s skin, Tea Tree essential oil is considered to strengthen skin`s resistance to external factors, sterilizing power and elasticity while preventing dry skin. For adults, Tea Tree essential oil is thought to help keep youthful skin by forming a protective film over it. And given the positive effects it has on the conditions of skin surface, there seems to be high possibility for Tea Tree essential oil to be used for the development of natural antibiotics and various medical cosmetics.

This study aims to analyze the differences in skin conditions and care methods according to skin types in middle-aged women, and to propose effective care methods to promote the formation of proper skincare habits. The study was conducted through a survey of 249 women aged 40-60 from April 29 to May 3, 2024. The results showed that middle-aged women with dry skin had prominent issues with moisture deficiency and wrinkles, those with oily skin experienced excess sebum and breakouts, and those with sensitive skin exhibited high sensitivity. Therefore, personalized care tailored to each skin type is necessary, with an emphasis on exfoliation for dry skin. The findings indicate that personalized approaches considering the specific characteristics of skin conditions are essential for middle-aged women’s skincare. Skin elasticity and pigmentation emerged as significant factors. Ultimately, proper skincare education is crucial for improving skin health. Future research should include a comprehensive skincare guide encompassing various skin conditions and care methods.
