  • "Eating cosmetic" market comes to prominence worldwide. Inner Beauty has established itself as the top trend nowadays and is leading the health functional food market. Another noticeable trend other than beauty-from-within is that products using "plant-based" natural botanical raw material are increasing. Based on these trends above, we have developed a plant extract named Agatri® for skin health using Agastache rugosa. By ingesting Agatri®, it is expected that the formation of skin wrinkles is suppressed, and skin elasticity is increased by suppressing the decrease in collagen content caused by ultraviolet rays. At the same time, it is possible to prevent skin aging by improving skin hydration and trans-epidermal water loss (TEWL). The studies show that it significantly increased production of hyaluronic acid and collagen, and decreased production of matrix metalloproteinases (MMPs). And Agatri® has been approved as an "Individually recognized functional ingredient for skin health by the Ministry of Food and Drug Safety, Korea in 2020. As a result, Agatri® is a good solution for those who are in need of skin protection from exposure to UV and aging.

  • Objectives The purpose of this study is to confirm the effect of alleviating inflammation through creating skin fat barrier from Scutellaria baicalensis extract. Methods Four-week-old Balb/C mice were divided into four groups: control group (Ctrl), lipid barrier eliminated group (LBEG), dexamethasone (DM) treated group after lipid barrier elimination (DMTG), and Scutellaria baicalensis (SB) treated group after lipid barrier elimination (SBTG). Scutellaria baicalensis extract were administered for 5 days after removal of the fat barrier. Changes in skin condition, improvement of the fat barrier, and relief of inflammation were observed in each group. Results Compared to LBEG and DMTG, pathological skin damage and tissue changes were less in SBTG, and transepidermal water loss (TEWL) and pH were also significantly reduced. Filaggrin was also significantly increased in SBTG. KLK7, PAR-2, and TSLP in SBTG also showed significant reduction compared to the LBEG and DMTG. Conclusions Scutellaria baicalensis extract restores skin barrier and relieves inflammation through the creation of skin fat barrier. This means that the Scutellaria baicalensis extract can regulate Th2 differentiation through the creation of the epithelial fat barrier.

  • Objectives : HRHDT has been known as a useful prescription with antibiotic, anti-inflammatory, antioxidative and immunosuppressive activity. To evaluate anti-inflammatory effect of HRHDT, we treated HRHDT-skin in Balb/c mice model induced contact hypersensitivity. Methods : Contact hypersensitivity, a local inflammatory respinse of skin, was induced by spreading the back skin of Balb/c mice with 1% DNCB. HRHDT-skin was prepared by dissolving 3% 1,3-butylene glycol extract of HRHDT in solution and treated 2 weeks on the back skin. Results: HRHDT-skin significantly reduced TEWL and erythema by 0.4-1% of DNCB treatment compared with control group. HRHDT-skin reduced IgE on serum obtained from blood of DNCB-treated Balb/c mice. Histopathological examination showed that thickening of the epidermis, hyperkeratosis and the infiltration of inflammatory cells were found in Balb/c mice under conventional circumstances. Conclusions : These results showed that HRHDT-skin could be used as a pharmaceutical material with antiinflammatory effects by reducing IgE in contact hypersensitivity dermatitis Balb/c mice by DNCB.

  • Objectives: To investigate the characteristics of topical agents including natural products using for atopic dermatitis treatment via a review on the cases and clinical trials. Methods: Through a search on Pubmed, EMBASE, Cochrane library, DBPIA, NDSL, and OASIS, we selected papers that applied natural products externally for atopic dermatitis and analyzed them. Results: Finally, Seventeen papers were selected. As the primary outcome, changes in the SCORAD and EASI, were the most used. The most frequent type of external formulation was cream. In terms of the frequency of use, it was used at least twice a day in all studies. When evaluated based on SCORAD, EASI, SH and TEWL, the improvement effect on atopic dermatitis was highest when the ointment formulation and the moisturizer formulation were used. A few side effects of topical agents including natural products were observed, but most were mild symptoms and no serious side effects occurred. Conclusion: This study is meaningful in that it has drawn a significant trend for studies that have been published in the last 5 years that contain a single intervention for topical agents including natural products, and that it presents the direction and evidence for the application of external therapy to increase the therapeutic effect of atopic dermatitis.

  • Naturally derived diosmetin and its glycoside diosmin are known to be effective in treating inflammatory disease. This study was performed to determine whether diosmin and diosmetin have the effect of improving atopic dermatitis in a 2,4-dinitrochlorobenzen (DNCB)-induced atopic dermatitis (AD) model. DNCB was used to establish AD model in hairless mice. Skin moisture, serum immunoglobulin E (IgE), interleukin 4 (IL-4), and histological analysis were performed to measure the effectiveness of diosmin and diosmetine to improve AD. IL-4 levels were also measured in RBL-2H3 cells. Administration of diosmetin or diosmin orally inhibited the progress of DNCB-induced AD-like lesions in murine models by inhibiting transdermal water loss (TEWL) and increasing skin hydration. Diosmetin or diosmin treatment also reduced IgE and IL-4 levels in AD-induced hairless mouse serum samples. However, in the in vitro assay, only diosmetin, not diosmin, reduced the expression level of IL-4 mRNA in RBL-2H3 cells. Diosmin and diosmetine alleviated the altered epidermal thickness and immune cell infiltration in AD. Diosmin is considered effective in the cure of AD and skin inflammatory diseases by being converted into diosmetin in the body by pharmacokinetic metabolism. Thus, oral administration of diosmetin and diosmin might be a useful agent for the treatment of AD and cutaneous inflammatory diseases.

  • Objectives: In order to accurately measure skin moisture and accumulate normal skin moisture data, analyzing the uncertainty of the skin moisture measurement and establishing standard reference data is essential. It helps to evaluate the skin's condition and has great significance in diagnosis and treatment. In this study, the traceability of the equipment and the uncertainty of the results were analyzed for their potential use in the field of Korean medicine. The data was collected measuring skin moisture on the sole of the foot. Methods: One professional measured the moisture of the adult male's foot 10 times following a determined protocol. The standard uncertainty of repeated measurements was calculated from the mean value of 10 repeated measurements. Ten trainee participants also measured the adult male's foot following a determined protocol. The standard uncertainty by tester was calculated from the value of repeated measurements. Results: As a result of analyzing the difference between the mean and standard uncertainties in both the expert and trainees, it was confirmed that the variance in this study did not satisfy the normal distribution. In addition, the Mann-Whitney U-test was carried out, and it was found that there was no significant difference in the measured values of the two groups. The authorized uncertainty of measurements and traceability of all the equipment was not confirmed. Conclusions: This paper establishes the basis for later measurement-equipment research to provide the objective indicators to approach the dryness of plantar skin from dehydration, the Korean medicine perspective.

  • The aim of our study was to evaluate the potential benefits of an oral supplement containing porcine placenta extract (PPE) on skin parameters related to cutaneous physiology and aging. PPEs were administered orally to hairless mice for 12 wk. The effects of oral PPE administration on skin water-holding capacity and Transepidermal Water Loss (TEWL) were similar to those of oral collagen (HYCPU2) administered as a positive control. Magnified photographs and replica images showed a reduction in UVB-induced wrinkle formation after collagen and PPE treatments. PPE treatments ameliorated the thicker skin surface that results from UVB exposure, based on a histological examination of skin tissue. The groups that were orally administered PPE (0.05%, OL; 0.1%, OH group) showed significantly reduced Matrix Metaloproteinase-2 (MMP-2) mRNA expression levels compared with the UVB control (Con), by 33.5% and 35.2%, respectively. The mRNA expression of another collagen-degrading protein, MMP-9, was also significantly lower in the groups that received oral administration of PPE (especially in the OH group) than in the control group. Additionally, oral administration of PPE significantly upregulated tissue inhibitor of metalloproteinase-1 (TIMP-1) and -2 mRNA expression levels compared with expression levels in the control group (p<0.05). This indicates that orally administered PPE activated the expression of Timp-1 and -2, inhibitors of MMP, which is responsible for collagen degradation in skin. Taken together, we propose that long-term oral administration of PPE might have a beneficial effect with respect to skin photo-aging.

  • Objective : Skin barrier protects skin against harmful environment. Its function includes antimicrobial barrier as well as physical barrier. But there are few studies about skin barrier function about men and women who don't have skin disease. The aim of this study is to investigate skin barrier function healthy men and women show. Method : There are many ways to measure skin barrier function, but lately transepidermal water loss is mainly used to know skin barrier function. Transepidermal water loss was measured over eight four the Korean twenties and thirties who don't have skin disease from March 14th, 2007 to March 16th 2007. We surveyed cubital fossa and cheek beside nose to measure transepidermal water loss and used vapometer. Result : After analyzed data, we concluded that cheek showed higher transepidermal water loss than cuital fossa. At cheek, the thirties had higher transepidermal water loss than the twenties. The male got higher transepidermal water loss than the female at cheek and in the average. And temperature and humidity effected on transepidermal water loss. Conclusion: In our study, it was observed that temperature and humidity effected on transepidermal water loss. In traditional korean medicine, the inbalance of cold(寒), heat(熱), dryness(燥), wetness(濕) makes many diseases and the inbalance of them induces dameum(痰飮) and the disorder of blood flow. Dameum(痰飮) and the disorder of blood flow make skin diseases made by abnormal skin barrier function in many ways. So we need to study dameum(痰飮) and the disorder of blood flow to take care of patients who have abnormal skin barrier function.
