  • The effects of Lactic acid bacteria have been investigated on anti-tumor. cholesterol reduction in blood. promotion of immune and skin-beauty. We are focused on cosmeceutical activity of Lactic acid bacteria (LAB). Ml, which is found in Korean traditional food. Kimchi The LAB.Ml has been identified as Lactobacillus plantarum Ml and individually cultured with Soybean soup and Soybean-Curd whey, until the total acidity has been reached the highest. After then, cell-free extracts from Ml have been used for the following studies. We assessed the effect of Lactobacillus plantarum Ml on the depigmentation of B16FlO melanoma cell. The melanin content of cells was decreased with 1-3% of cultured extracts. The tyrosinase activity was reduced by cell-free extracts of Lactobacillus plantarum Ml. Anti-aging and anti-oxidative activity of Ml cultured extract was also studied in NIH-3T3 human fibroblast cells. It showed that induction of cell proliferation. collagen synthesis and free radical scavenging activity. Additional studies for anti-fungal and anti-acne activity were also detected on Staphylococcus aureus and Propionibacterium acnes, respectively. These results suggest that cultured extract of Lactobacillun plantarum Ml would be used for cosmeceutical ingredients through multifunctional reaction on skin such as whitening, anti-wrinkle. anti-oxidation and anti-acnes.

  • Wrinkle formation and dryness are the most well-known symptoms of skin aging. This study investigated skin anti-aging and moisturizing effects of Mugunghwa (Hibiscus syriacus L.), the national flower of Korea. The effect of H. syriacus L. flower extract was examined in skin cells originating from humans in vitro and in hairless mice exposed to UVB in vivo. The in vivo study results showed that skin hydration-related factors such as involucrin, filaggrin, HAS1, HYAL1, and matrix metalloproteinase-I (a primary skin photoaging factor) were regulated by H. syriacus L. Additionally, epidermal thickness and collagen disruption, which resulted in wrinkle formation and skin dryness, were ameliorated by oral administration of H. syriacus L. These results indicate that H. syriacus L. flowers can play important roles in preventing aging and promoting skin moisturizing.

  • Recently, the importance of individual skin characteristic is emphasized for customized beauty products. There are many studies on the concept of the syndrome differentiation, related to individual cosmetics in Korean Medicine. However, skin characteristic according to Yin deficiency syndrome (YDS), which is associated with aging, are yet to be clarified. The objective of this study was to evaluate the skin characteristic and questionnaire of female with YDS compare to with non-YDS. 218 healthy females between 40 and 59 years of age were assessed for the skin hydration, elasticity, brightness (L* value), redness (a* value), pore, pigmentation, wrinkle, and sebum by Corneometerr®, Cutometerr®, and Janus lll. Independent t-test showed lower hydration, lower elasticity, and higher redness in the YDS group compared to the non-YDS group (all p < 0.05). There was significant difference on the facial fever, insomnia, decreased amount of urine, and skin sensitive checklist. These results suggested that using the questionnaire associated with YDS and skin characteristic could separate skin types and apply to customized beauty products.

  • Recent studies have revealed that collagen peptide (CP) plays a protective role in skin by improving the activity of antioxidants and acts as an inducer of skin regeneration by positive feedback. In this study, we focused on the beneficial effect of reinforcing the CP skin barrier. To evaluate the skin barrier, hairless mice were exposed to UVB irradiation and acetone-treatment, with or without oral administration of CP. The effects on skin appearance, trans-epidermal water loss, epidermal thickness, and cytokine content were measured using bioengineering and histochemical methods. In the CP treated group, the skin had better appearance and less damage than that of the control. Furthermore, in HaCaT cells, the amount of serinepalmytoyl transferase (SPT) mRNA increased by about 1.6-fold after treatment (CP, 100 mg/L), reflecting that CP can induce SPT expression and reinforce the recovery of skin barrier function. These results suggest that CP is not only an anti-wrinkling agent but also a potent candidate as an epidermal moisturizer.

  • Skin basement membrane (BM) is a specialized structure that binds dermis and epidermis of the skin and plays an important role in maintaining skin structure. Structural change and destruction of BM is reported to appear due to UV exposure and aging, which may contribute to skin aging including wrinkle formation and a decrease in elasticity of the skin. One of the key components of the BM is laminin-332 (LN-332), and is a major contributor to epidermal-dermal attachment. In this study, we elucidated the effects of Meladrium firmum hexane fraction (MFHF) on LN-332 expression in HaCaT, a human keratinocyte cell line. Quantitative real-time PCR (RT-PCR) and immunoblot analysis revealed that MFHF induced upregulation of LN-332 gene and protein expression. Next, cells were treated with p38 MAPK inhibitor (SB202190) prior to MFHF treatment to analyze the signaling pathway contributing to LN-332 expression. The mRNA and protein levels of LN-332 expression were suppressed completely by pretreatment with p38 MAPK inhibitor. Furthermore, MFHF also increased the mRNA level of collagen type VII and integrin ${\alpha}6$ of skin BM component. These results collectively suggest that MFHF may have potential as an effective agent to stimulate the synthesis of BM components, and could be used to improve phenomenon of skin aging ascribed to the structural and functional impairments of BM in aged human skin.

  • In this study, we report the results of a study on the clinical evaluation of wrinkle improvement by developing a method for liposome of high-purity Centella asiatica extract used in pharmaceuticals and cosmetics, and a cream using the same. In order to make Centellasome-10EX stabilizing centella asiatica extract in liposome lamella vesicle, it could be completed using 5% hydrogenated lecithin and 2% sucrose distearate. The appearance of Centellasome-10EX was a creamy form of low viscosity, the color was pale yellow, and the odor had the inherent odor of the raw material. The pH was about 6.12, the specific gravity was 1.09, and the acid value was about 0.35. The content of the main constituents of centella asiatica extract contained in the liposome vesicle contains 10,800 ppm of asiatic acid, 10,900 ppm of asiaticoside, 6,000 ppm of madecasic acid, and 1,600 ppm of madecassoside, and long-term storage. There was no discoloration even at the time, and it was found that the main component remained stable thermodynamically. To mechanistically analyze the structure of the liposome vesicle of Centellasome-10EX, as a result of observation with a transmission electron microscope (Cryo-TEM), the multilayer vesicles are formed and filled with moisture, and there are 10 to 60 multilayers around it. It was confirmed that the liposome lamella vesicle was formed. As a clinical trial (in-vivo) test, the moisturizing effect of centellasome cream after application for 5 weeks was 28.3%, which was significantly increased compared to placebo. The skin elasticity effect was 13.6%, which significantly increased the moisturizing power than the placebo. The effect of improving fine wrinkles around the eyes was improved by 23.52% compared to placebo cream. Through the results of this study, it was possible to study the formulation and manufacturing method for encapsulation and stabilization of the developed Centellasome-10EX in the liposome vesicle. It is expected that the results obtained through clinical research on the wrinkle improvement effect of the cream using this can be widely used to study skin science in the cosmetic industry and to develop high-quality cosmetics with high efficacy.

  • As a result of measuring the polyphenol content of Humulus japonicus (HJ) extract according to the collection time and extraction solvent, bothhot water extract and 70% ethanol extract were collected and extracted in June, and the polyphenol content was high. When the harvesting time was the same, the polyphenol content of the ethanol extract was higher than that of the hot water extract. As a result of measuring the antioxidant activity of HJ extract by measuring electron-donating ability, SOD-like activity, and ABTS radical scavenging ability, HJ6E, which has the highest polyphenol content, showed the highest activity. In addition, in the case of the extract collected in August, the polyphenol content was similar. However, the antioxidant activity of the ethanol extract was high, sothe antioxidant activity remained high when extracted with 70% ethanol. As a result of measuring tyrosinase inhibitory activity for evaluating skin whitening activity, HJ6W did not show any activity. The activity at the highest concentration was 16.18% for HJ8W, 8.07% for HJ6E, and 14.7% for HJ8E. Therefore, the content of ingredients showing skin whitening activity was higher in August than in June. In the elastase inhibitory activity for evaluating the anti-wrinkle activityof the skin, the ethanol extract showed very little activity, and the hot water extract did not. In addition, since all extracts do not show astringent activity, it is judged that it is not appropriate to use HJ as a functional ingredient for preventing wrinkle formation. As a result of measuring the cell viability of HJ6E, which showed the highest polyphenol content and antioxidant activity, it showed a cell proliferation effect at low concentrationsbut strong cytotoxicity at concentrations above 50 ㎍/mL. In the case of the NO production inhibitory ability, as the concentration increased, the NO production of Raw 264.7 was suppressed. Theamount of NO production at 1,000 ㎍/mL decreased to 40.7%. However, whether these results are due to cytotoxicity or the extract's efficacy is a part that requires further research.

  • The aim of this study is to evaluate the effect of cosmetic products containing concentrated ginseng using novel methods based on Traditional Korean medicine (TKM). In TKM, inspection of facial skin was an important method to diagnose symptoms and body condition of patients. Doctors in oriental medicine examined a patient as observing symptoms on the face and skin related to inner organs. This was called "mang-jin. In this study, eleven female, who have been using the cosmetic products containing concentrated ginseng for the last 5 years, and eleven healthy controls, who have never used the same product, were recruited. Three doctors in oriental medicine evaluated 17 inspection factors on facial skin. And 7 non-invasive skin bioengineering factors were assessed by various instruments at the same time. In results, 7 factors of the inspection were better in using the product than in controls. And sebum, roughness, pigmentation and wrinkle depth were significantly lower in using the product than in controls. So, this results propose that the cosmetic product containing concentrated ginseng has a good anti-aging effect on skin. And it is suggested that the novel evaluation method combined, Traditional Korean medicine and modern bioengineering technique, has to be developed for holistic concept of Hanbang cosmetics.

  • Antioxidant, antibacterial, and skin penetration tests were conducted to investigate the skin absorption of Pyrus serotina var leaf extracts using polymer micelles and their applicability to cosmetic ingredients. Total polyphenol content was found to be $118.83{\pm}9.39mg/g$ in Pyrus serotina var leaf ethanol extract and $106.89{\pm}4.45mg/g$ in Pyrus serotina var leaf hydrothermal extract. The DPPH radical scavenging activity was found to be the highest radical scavenging activity of $74.39{\pm}7.48%$ of the Pyrus serotina var leaf ethanol extract at the concentration of 500 mg/L. The SOD-like activity was $91.62{\pm}0.43%$, the highest value at the concentration of 1,000 mg/L in the hydrothermal extract. After the experiment, antioxidation, wrinkle improvement and whitening activity were confirmed, and the Pyrus serotina var leaf extract was highly likely to be realized as antioxidant and antibacterial material. In the skin penetration experiment with the Pyrus serotina var leaf ethanol extract, the permeation amount of total accumulated tannic acid was found to be Formulation 2 ($55.45{\mu}g/cm^2$), Formulation 1 ($46.43{\mu}g/cm^2$), Formulation 0 ($34.36{\mu}g/cm^2$). In the liposome's skin penetration experiment containing pear leaf hydrothemal extract, the total amount of accumulated tannic acid permeation was found to be Formulation 5 ($75.01{\mu}g/cm^2$), Formulation 4 ($64.01{\mu}g/cm^2$) and Formulation 3 ($36.60{\mu}g/cm^2$). Through this study, we confirmed the possibility of antioxidant and wrinkle effects of Pyrus serotina var leaf extract. In addition, as a result of skin penetration through the production of polymer micelles and liposome containing Pyrus serotina var leaf extract, It will be more usable in cosmetic industry.
