Recently, the beauty industry has implemented personalized services based on skin big data. To increase competitiveness in the beauty industry, systematic data measurement and evaluation indicators are necessary to select data and obtain necessary knowledge. In response, this study sought to stably enhance the accuracy of skin diagnosis based on satisfaction and reliability. To this end, the research was conducted through focus group interviews (FGI), a case study of brands, and analysis of prior research results. In particular, as a result of analyzing keywords that classify skin types by brand, common survey items for skin types were oiliness and using moisturizer, cosmetic use and vascular of skin, external stimulus and blemish & freckles, facial wrinkle, outside activities, self-consciousness, and smoke. In additioin to the common questions of the preceding study and the brand survey items, the questions concerning complex skin types, seasonal change, facial color, wrinkles and elasticity were added, and the questions were presented in a total of 40 items. In particular, it suggested that skin measurement could be conducted by focusing on elasticity and pigmentation items by reflecting the results of prior research and the opinions of FGI, and based on this, a customized service with high satisfaction and high accuracy of beauty care based on this could be proposed. We hope that this study will facilitate active self-care by providing more satisfying skin stones and personalized cosmetics proposals, thus laying the foundation for the further development of the cosmetics industry.

Acerola is an excellent ingredient because of its high natural vitamin C content, but it is difficult to stabilize and has hardly been studied as a cosmetic material. Therefore, this study developed a mixed liposome preparation for stabilizing acerola extract. As a safety test, the skin irritation test was evaluated by BCOP assay and HET-CAM assay. We evaluated the inhibition of tyrosinase activity, the whitening effect of melanin production, and the wrinkle effect of prochloragentype-I C-peptide production, and confirmed the possibility of functional cosmetics. In addition, a cream of liposomes containing acerola extract mixture was developed to evaluate the clinical studies of skin wrinkles and whitening. BCOP assay, HET-CAM assay and human skin primary irritation test results of liposomes containing acerola extract mixture showed no irritation and were safe from skin and eye. The result of tyrosinase activity by 75.8% at 1,000 ㎍/mL. As a result of the melanogenesis inhibition test, liposome with acerola extract showed the melanin content by 46.2% at 1,000 ㎍/mL that does not effect the viability of the B16F10 cell line. The result of collagen production test using ELISA kit, liposomes containing acerola extract mixture showed collagen synthesis ability by 152.1% at 1,000 ㎍/mL that does not affect the viability of the HS68 cell line. But it did not showed any inhibition of collagenase (MMP-1) activity at all concentrations in the MMP-1 activity inhibition test in the HS68 cell line. We performed clinical studies for the whitening and skin-wrinkle activity of cream containing acerola extract mixes liposome, was showed that the melanin contents and wrinkle was statistically significant reduction. These results suggest that liposomes containing acerola extract mixture have safe natural material, and skin wrinkle, whitening effects allowing their application in cosmetics as a natural product.

UV irradiation causes skin-aging involving coarse wrinkles, thickening, dyspigmentation, and rough skin surface. These phenomena in complex skin tissue is controlled with receptor of cell surface growth factor and cytokine receptors. The activation of receptors induces multiple downstream signaling pathways including expression of MMPs (matrix metalloproteinases). This study was aimed to elucidate the mechanism for anti-wrinkle activity of Korean red ginseng, Torilis fructus and Corni fructus mixture (KTNG0345). In this animal study, we have investigated decreasing effects of Korean red ginseng mixture on MMP-3 synthesis through diminishing $TNF-{\alpha}$ signaling that express MMP-1, -3, and -9. c-Jun and c-fos as a component of transcription factor AP-1 (activator protein-1) were analyzed the expression level using real time PCR and western blotting. c-Jun was decreased dose dependent manner both gene and protein level where as cfos was not changed. In upstream, JNK and PAK was not changed, but p38 was decreased in down stream. MMP-3, final product in this pathway was significantly decreased in dose dependent manner. These results suggest that Korean red ginseng mixture have a anti-wrinkle activity through $TNF-{\alpha}$ mediated MMPs expression pathway.

Aging in humans is inexorable and inescapable. The progressive decrease of physiological capacity and the reduction of the ability to cope with environmental stresses lead to increased susceptibility and vulnerability to human disease. Recently, in the cosmetic industry, many researchers have paid considerable attention to delaying or improving the symptoms of skin aging. Since the early 1990`s, there have been various challenges in developing cosmeceutical products which have strong anti-aging effects, and this has been an important issue in the cosmetic industry. Meanwhile, development of anti-aging cosmetics supported by biochemical activities in the skin has been researched. Castanea crenata inner Shell solvent extracts were investigated for anti-wrinkle and whitening effects, in order to apply it as a functional ingredient for cosmetic products. For anti-wrinkle effect, elastase inhibition activity of Castanea crenata inner shell acetone extract (CA) was 51.0% at a concentration of 100 ug/ml. The collagenase inhibition activity of CA and Castanea crenata inner shell ethanol extract (CE) was 96.4%, 94.3% at a concentration of 50 ug/ml. The tyrosinase inhibitory effect, which is related to skin-whitening, was 47.2% and 45.8% in CA and CE at a concentration of 500 ug/ml. All these results suggest that Castanea crenata inner shell can be effectively used as a cosmeceutical ingredient for the prevention of wrinkles.

In this study, cosmeceutical activities of the co-cultures of both lactic acid bacteria isolated from the hands of women, Lactobacillus rhamnosus (L. rhamnosus) and Lactobacillus paracasei (L. paracasei) were first reported: For whitening and anti-wrinkle activities, the co-culture showed the highest tyrosinase inhibition of 20.68%, compared L. paracasei and L. rhamnosus. The co-culture also showed the highest inhibition of melanin synthesis as 63.7%. In observing the anti-wrinkle activities of the co-culture, it generated only 3726.3 pg/mL of matrixmetalloproteinase-1 (MMP-1) production when 13613.5 pg/mL and 13012.0 pg/mL of MMP-1 production were estimated from L. rhamnosus and L. paracasei. Besides these, the extract from the co-culture yielded higher collagen production as 380.7 ng/mL, compared to 323.4 ng/mL and 304.1 ng/mL from L. paracasei and L. rhamnosus. These results indicate that the co-culture of both lactic acid could improve its cosmetic activities. This hypothesis was also confirmed that the co-culture of both bacteria showed strong antioxidant activities of DPPH free radical scavenging while the extract of L. rhamnosus and L. paracasei.

Wood vinegar is well known as a softening agent affecting on the stratum corneum that is easy to penetrate into the skin. In this study, we prepared mixed ursolic acid hydrogel with wood vinegar(1, 2, 5%) as a penetration enhancer. The accumulation of ursolic acid in the skin from hydrogels was evaluated in vitro hairless mouse skin and skin moisturizing effect of them was evaluated using the corneometer and the tewermeter. And the role of stratum corneum as a protective barrier was evaluated as well. The hydrogels were retained about 40% of water retention capacity 2hrs and had better effect on the stripped skin than full-thickness skin. The accumulation of ursolic acid through stripped skin from hydrogels with wood vinegar was not change compared to normal skin, which indicated the action site of wood vinegar and the accumulation site of ursolic acid would be stratum corneum. From these result, we could find wood vinegar seems to be a good enhancer for active materials with anti-wrinkle and anti aging effect such as ursolic acid, and can be a developed topical delivery system maintaining excellent water retention capacity.

Fructose-1, 6-diphosphate (FOP), a glycolytic metabolite is reported to ameliorate inflammation and inhibit the nitric oxide production in murine macrophages stimulated with endotoxin. It is also reported that FOP has cytoprotective effects against hypoxia or ischemia/reperfusion injury in brain and heart. In this study, we examined whether FDP has protective effects on UV-induced oxidative damage in skin cell culture system and human skin in vivo. FDP had a protective role in UVB-induced LDH release and ROS accumulation in HaCaT although it did not show direct radical scavenging effect in the experiment using 1, 1-diphenyl-2-picrylhydrazyl (DPPH). FDP also preserved cellular GSH content after UV irradiation in HaCaT and normal human fibroblast culture system. Cellular oxidative stress induces multiple downstream signaling pathways that regulate expression of multiple gene including MMP-1 and collagen, we examined the effects of FDP on UV-induced alteration of these protein expression in fibroblast culture and human skin in vivo. The increased MMP-1 expression in fibroblast and human skin by UV irradiation was significantly decreased by FDP. FDP also prevented the UV-induced decrease of collagen expression in fibroblast and human skin. Moreover, the decreasing the intracellular levels of reducing equivalents in human fibroblast by glutathione (GSH) depletion lowered the UVA dose threshold for reduction of procollagen expression, indicating that the differences of glutathione contents define the susceptibility of fibroblasts towards UV-induced reduction of procollagen expression. FDP also preserved cellular GSH content after UV irradiation, indicating that FDP has protective effects on UV-induced reduction of procollagen expression, which are possibly through maintaining intracellular reducing equivalent. Based on these premises, we examined the effect of daily use of a moisturizer containing FDP on facial wrinkle in comparison with vehicle moisturizer lacking FDP. In the clinical study, FDP significantly decreased facial wrinkle compared with vehicle alone after 6 months of use. Our results suggest that FDP has anti-aging effects in skin by increasing cellular antioxidant system and preventing oxidative signal and inflammatory reaction. Therefore FDP may be useful anti-aging agent for cosmetic purpose.

Background: During the aging process, skin shows visible changes, characterized by a loss of elasticity and the appearance of wrinkles due to reduced collagen production and decreased elasticity of elastin fibers. Panax ginseng Meyer has been used as a traditional medicine for various diseases due to its wide range of biological activities including skin protective effects. Ginsenosides are the main components responsible for the biological activities of ginseng. However, the protective activities of an enzymatic preparation of red ginseng against human skin aging have not been investigated. Methods: The efficacy of an enzyme-treated powder complex of red ginseng (BG11001) in preventing human skin aging was evaluated by oral administration to 78 randomized individuals. All patients were requested to take three daily capsules containing either 750 mg of BG11001 or a placebo vehicle for 24 wk; at the end of the testing period, skin roughness, elasticity, and skin water content were measured. Results: BG11001 significantly reduced the average roughness of eye wrinkles and the Global Photo Damage Score compared with the placebo, although there were no significant differences in arithmetic roughness average between the groups. In addition, gross elasticity and net elasticity values increased, and transepidermal water loss level decreased, indicating improved skin elasticity and moisture content. Conclusion: In conclusion, enzyme-treated red ginseng extract significantly improved eye wrinkle roughness, skin elasticity, and moisture content. Moreover, enzyme-treated red ginseng extract would be useful substance as a bio-health skin care product.
