  • Sasang Constitutional Medicine (SCM) suggests the concept of health condition which is owned of different properties by each Sasang Constitution. But SCM theory has concentrate to explaining different symptoms that distinguish health condition, not much concerned with practical methods like face features, pulse diagnosis, skin surface properties and voice features. Physical properties of practical diagnosis methods from literature finding have been researched. As a result, complexion and face moisture were described to be physical properties related to health State. In scope of pulse diagnosis, depth, rate, contour, width and pressure are related. Skin surfaces' elasticity, moisture, fraction properties were also suggested as factors of health State of Sasang Constitution. We assume that this study would contribute further studies for objectifying and quantifying diagnosis methods to evaluate health state grades of Sasang Constitution.

  • Some researchers suggested that tactile sensor system would be useful in evaluating masticatory muscles of TMD patients, but there were few studies on the effects of chewing with time. The aim of this study was to investigate the change of elasticity and stiffness for masseter and temporal muscles of normal subjects before, during and after gum chewing and to obtain the baseline data for further researches on the elasticity and stiffness for masticatory muscles of TMD patients. Stiffness and elasticity of their anterior temporalis and inferior masseter muscle were measured bilaterally by a tactile sensor system. Each subject was instructed to sit on a chair for evaluation of masticatory muscles. Before operating the sensor, the thickest skin area over anterior temporalis and inferior masseter muscles were selected as the points to be pressed by a tactile sensor, and marked with a pen. While the teeth of subjects were lightly contacted, the probe of the tactile sensor was placed perpendicularly over the marked point over the skin, followed by computer-controlled movement including gently pressing straight down on the muscle for a second and retracting. All subjects were instructed to chew gum (Excellent Breath, Taiyo Co., Japan) bilaterally with a velocity of 2 times per second for 40 minutes after the first measurement had been performed for the baseline data of all subjects. The measurements had been repeated during chewing with 10 minutes of interval and continued for 40 minutes with same interval after chewing. Resultantly, the decrease of elasticity and the increase of stiffness in masticatory muscles can be seen significantly within 10 minutes after chewing and those were maintained during chewing without significant change with chewing time. The elasticity of muscles was recovered within 10 minutes after stopping chewing, but the stiffness was recovered more lately than elasticity by about 10 minutes. Based on these results, it can be concluded that elasticity and stiffness of muscles would be good indicators to evaluate the masticatory muscles objectively, when more supported by further researches.

  • Background The elasticity of the back skin of the rat reduced the tension around wounds during the wound healing process in that region, and thus activates wound contraction. The authors proposed two skin fixation methods using readily available materials to decrease the influence of wound contraction on wound healing and designed an experiment to determine their effects. Methods The authors made 36 skin wounds on the backs of 18 rats, and they divided them into three groups. Each group was treated with three different kinds of dressing materials, each with different skin fixing characteristics. Group A was a control group. Group B and group C were dressed by the first and the second skin fixation method. We measured the areas of the wounds post-surgically and calculated the wound area reduction rates. Results The two skin fixation methods both reduced the effect of wound contraction compared to the control group. Each of the two methods had different outcomes in reducing wound contraction. Conclusions The experiment demonstrated significant differences among the wound areas and the wound area reduction rates of the three groups as a result of differences in the degree of wound contraction. To obtain accurate results from wound healing experiments, appropriate skin fixation methods must be adopted.

  • Background: In aged skin, degradation of collagen fibers, which occupy the majority of the extracellular matrix in the dermis, and changes of aquaporin 3 (AQP3) and skin constituents, such as hyaluronic acid and ceramide, cause wrinkles and decrease skin moisturization to contribute to dryness and lower elasticity skin. Red ginseng (RG) is used as a cosmetic and food material and is known to protect from UVB-induced cell death, increase skin hydration, prevent wrinkles, and have an antioxidative effect. But, in general, RG used as a material is the soluble liquid portion in the solvent, and the part that is not soluble in the solvent is discarded. Thus, we made the whole RG into microgranulation and dispersed in water to produce gel form for using entire RG, and it was named red ginseng NaturalGEL (RG NGEL). Methods: RG NGEL was investigated for matrix metalloproteinases inhibitory activity, induction of Type I collagen, AQP3, hyaluronan synthetase 2, serine palmitoyl transferase, ceramide synthase 3, and filaggrin expression and compared with RG water extract. Results: RG NGEL reduced the levels of UV-induced matrix metalloproteinases and increased Type I collagen in human fibroblast cells and upregulated AQP3, hyaluronan synthetase 2, serine palmitoyl transferase, ceramide synthase 3, and filaggrin expressions in human keratinocytes compared with RG water extract. Conclusion: RG NGEL has the potential as an effective reagent for antiaging cosmetics to improve wrinkle formation and skin hydration.

  • The purpose of this study was to investigate the effects that body composition, nutrient intake, and biochemical indices have on skin status, as well as their associations with skin health status, by assessing 44 female university students. The subjects were classified into 3 groups according to skin sensitivity: sensitive skin (n=11), slightly sensitive skin (n=24), and normal skin (n=9). The study included anthropometric measurements and body composition analyses, dietary intake evaluations, blood chemical analyses, and skin health status assessments. Based on % body fat, the results indicated the subjects were moderately obese (29.6%). Obesity indices were not different among the groups, but the sensitive skin group tended to have higher skinfold thickness. Dry skin was determined as the skin type of all subjects. In the sensitive skin groups, U-zone and T-zone sebum were significantly lower (p<0.05), and spots were significantly higher (p<0.05) than in the normal skin group. In terms of nutrient intakes, the sensitive skin groups consumed significantly lower amounts of P and vitamins A and E (p<0.05). There were no significant differences in serum lipid fractions or total antioxidant status among the groups. In correlation coefficients analysis, skin elasticity had significant negative correlations with subscapular and midaxillary skinfold thickness, body protein, and body minerals (p<0.05). Wrinkling had positive correlations with triceps and thigh skinfold thickness (p<0.05). Skin evenness had negative correlations with energy intake, vitamins A, $B_1,\;B_2$, C, E, niacin, and zinc (p<0.05), as well as folate and P (p<0.01) and vitamin $B_6$ (p<0.001). A similar correlation tendency was observed for spots and nutrient intake, showing negative correlations with vitamins A, $B_6$, and E, as well as folate, Fe, and P. U-zone sebum showed significant positive correlations with serum levels of total cholesterol and triglycerides. From these findings, skin health status appears to be affected by both nutrient intake and body composition. Therefore, having a proper balance between dietary intake and body composition may influence skin health status in females with sensitive skin.

  • The aim of this study was proceed for 6weeks to determine the effect of middle-aged women's upper lips ms by SUKI programs. A total of 20 subjects were tested, and the SUKI arbitration programs of Pattern T1, Pattern T2, Pattern T3, Pattern T4 were adopted three times a week in six weeks. The results were as this. It showed a significant difference in the EG, although some of the intra-group comparisons of the upper lip ms. Therefore, SUKI programs have been shown to help improve the elasticity of the upper lip ms(p<.05). In this study, the SUKI program was used based on the fact that although limited, the elasticity of the upper lip ms, located in the facial part of a middle-aged woman, causes various wrinkles around her mouth, making them lose confidence in their appearance. This also suggests that normal facial ms can affect the appearance of the female middle-aged woman, and it was intended to suggest some ways to manage the appearance by proper management of facial muscle according to the life cycle of the female middle-aged woman. In conclusion, we hope that in the future, various experiments will be used as new research data on how to prevent women's facial skin beauty and wrinkles and help improve elasticity of facial muscles around the mouth.

  • Essential oils aims to rejuvenate and beautify medical skin care the body through the use of essential oils, and generally to improve our outward appearance. Much of this section fouses on the different methods by which essential oils can be used to improve the complexion or to treat specific medical care skin conditions. Beauty, however, is not just skin-deep. The condition of the medical care express the overall health of an individual. A relaxed attitude, together with a well-balanced diet, enough exercise, and a daily intake of plenty of spring water or herbal teas, all help to keep the system in top condition. Essential oils is a healing art which has powerful effects on both mind and body. The vital element in essential oils is the pure oils which are extracted from various part of different plants. The key to medical aromatherapy care lies in its dual use of essential oils and medical care massage, thus masking full use of two of our most important senses-smell and touch. Medical aromatherapy care is holistic, working mainly on the nervous system and including the head and body as part of the same treatment. Using pressure points along the spine, Medical aromatherapy care on the autonomic nervous system and has an immediate effect of relexation. In directly it also acts on mood. Many of the medical massage movements help lymphatic drainage. Essential oils have many different qualities; they can be relaxing or invigorating and are generally antisepic and antibacterial. Medical aromatherapy care can have psychological benefits. The power of essences in healing has been recognized in the treatment of insect bites. Clove, thyme, sandalwood, and lavender are a few of the essences that have antiseptic. Essential oils effect the dry skin for small visual pores, dull matte finish, rough sandy feeling, tantskin. Essential oils effect the mature/sun damaged skin for some red or couperose areas, loose saggy skin, exposure to a lot of ultraviolet light. Essential oils effect the medical care nomal skin good elasticity, healthy color(good circulation), smooth terture.

  • The cosmetic effects of epicutaneous treatment with extracts of Panax ginseng C.A. Meyer have been poorly investigated. The little published data found in cosmetic literature emphasize the activating effects on sagging and wrinkled skin and some favorable activities on dry and/or greasy skin. Earlier observations have shown the excellent skin tolerability of some liposomal ginseng extract preparations. No moisturizing and seboregulatory effects were demonstrated. but eutrophic effects on subjects with aging skin have been observed. The present study concerned the preparation of a special extract derivative obtained by Physical-chemical interactions of ginseng saponins and some phospholipids. which we have called 'fitosoma.' These complexes have been characterized by NMR spectroscopy and electron microscopy. Furthermore, these complexes are new. stable. and water microdispersible, forming liposomal structures in water. The cosmetic activities of these compounds have been examined by means of corneometry and elastometry to study their influence on aging skin. on skin layer hydration. and to determine skin elasticity.
