Combination of Nicotinamide and Agastache rugosa Extract: A Potent Strategy for Protecting Hs68 Cells from UVB-Induced Photoaging.

This study investigated the protective effects of nicotinamide (NAM) and Agastache rugosa extract (AR) against ultraviolet B (UVB)-induced photoaging in Hs68 cells. The results demonstrated that NAM and AR, alone or in combination, exhibited concentration-dependent protective effects against UVB radiation. The highest synergistic effect was observed at a NAM:AR ratio of 6:4. This combination exhibited a synergistic protective effect against UVB-induced photoaging. The sample concentration required for 80% cell survival was 9.70 μM and 131.16 ppm for NAM and AR, respectively. However, when combined, they exhibited strong synergistic effects with concentrations as low as 0.11 μM and 17.50 ppm. Moreover, 5.26 μM of NAM and 1,082.13 ppm of AR were required to inhibit 30% of reactive oxygen species, but the combination treatment required 0.62 μM and 95.49 ppm, respectively. This combination significantly reduced the production of matrix metalloproteinase and increased collagen production. These findings highlight the potential of combining NAM and AR as functional cosmetic materials to protect against UVB-induced photoaging. The synergistic effects observed in this study provide valuable information for developing novel strategies for cosmetic combinations that target UVB-mediated skin damage.

Results: Anti-oxidant activity of the TCE was 85.6%, and of TCW was 88.4% at 500 μg/mL. The size of the clear zone was confirmed using Cutibacterium acnes (18 mm), <i>Staphylococcus epidermis</i> (<i>S. epidermis</i> ) (4 mm), and <i>Staphylococcus aureus</i> (<i>S. aureus</i> ) (16 mm). No antifungal activity against <i>Candida albicans</i> was observed. RAW264.7 macrophages showed a survival rate of >90% at <250 μg/mL of extract. Additionally, a concentration-dependent inhibition of NO production was observed. Conclusion: Tart-cherry extracts possessed high anti-oxidant activity and anti-inflammatory efficacy. In addition to the antibacterial activity against the skin-residing bacteria, <i>S. aureus</i> and <i>S. epidermis</i>, high activity against the acne-causing strain <i>C. acnes</i> suggests a sufficient potential of Tart-cherry extracts as a raw material for the preparation of cosmetics and bioproducts.

Development of a Semi-Dry Method for Measuring Drug Permeation into Skin Using an Electric Facial Care Device and Iontophoresis

Introduction: Percutaneous drug delivery systems are attractive not only as a therapeutic strategy but also for cosmetic treatment. Iontophoresis is a well-recognized method for promoting transdermal absorption of ionized compounds. Franz cells are generally used to estimate drug permeation of skin by iontophoresis. However, methods using Franz cells are less versatile; for instance, the method is unsuited for use with a portable electric facial care device having a working probe of a certain size and weight. In this study, we constructed a semi-dry apparatus for use with an electric facial care device. Methods: The apparatus has a multilayer structure consisting of mouse skin and 3 filter papers, modeled after the Franz cell. The skin permeation of the drug edaravone (3-methyl-1-phenyl-2-pyrazolin-5-one) was then measured using this apparatus. Results: Edaravone permeation depended on working time, drug concentration, and ionization ratio of edaravone when iontophoresis was carried out with an electric facial care device. Furthermore, glycyrrhizic acid, α-tocopheryl phosphate, retinoic acid, and ascorbyl palmitate, which are recognized as functional cosmetic materials, also permeated the skin by applying iontophoresis with the device. Conclusion: These results suggest that the developed measuring apparatus is applicable for use with a portable electric facial care device and that iontophoresis using a portable electric facial care device is potentially useful in the cosmetic field.

In order to prepare basic data for examining the development of longbean (Vigna unguiculata ssp. sesquipedalis) as a possible natural material for functional cosmetics, the study investigated the yield, total polyphenol content, antioxidant, and the NO production inhibitory effects of an ethanol-produced extract of longbean soybean parts. As a result, the yield of the longbean ethanol extract was found to be 14.93% and the total polyphenol content was confirmed to be 4.36±0.473 mg/g. When the antioxidant effect was measured by the electron donating ability and the ABTS radical scavenging activity, the electron donating ability tended to increase as the concentration increased, and showed a high scavenging ability of 92.32% at a concentration of 1,000 μg/mL. And the ABTS radical scavenging activity showed a scavenging effect of 99.81% at a concentration of 100 μg/ml, and the scavenging effect was equivalent to that of vitamin C. As a result of measuring the antioxidant activity, the ABTS radical scavenging ability showed a higher scavenging effect than the electron donating ability. The cell viability of RAW 264.7 cells was 99.82-100.28% up to the concentration of 500 μg/ml, and cytotoxicity was not observed up to 500 μg/ml. The NO production inhibitory activity showed a significant decrease to 81.84% at a concentration of 500 μg/ml. Therefore, it is considered that the long bean ethanol extract can be used as a natural material for cosmetics. In future studies, it is necessary to demonstrate the physiological activity, such as anti-inflammatory mechanisms, whitening, and wrinkle improvement through component analysis.

Effect of Electron-Beam Irradiation on Functional Compounds and Biological Activities in Peanut Shells.

Peanut shells, rich in antioxidants, remain underutilized due to limited research. The present study investigated the changes in the functional compound content and skin aging-related enzyme inhibitory activities of peanut shells by electron-beam treatment with different sample states and irradiation doses. In addition, phenolic compounds in the peanut shells were identified and quantified using ultra-performance liquid chromatography with ion mobility mass spectrometry-quadrupole time-of-flight and high-performance liquid chromatography with a photodiode array detector, respectively. Total phenolic compound content in solid treatment gradually increased from 110.31 to 189.03 mg gallic acid equivalent/g as the irradiation dose increased. Additionally, electron-beam irradiation significantly increased 5,7-dihydroxychrome, eriodictyol, and luteolin content in the solid treatment compared to the control. However, liquid treatment was less effective in terms of functional compound content compared to the solid treatment. The enhanced functional compound content in the solid treatment clearly augmented the antioxidant activity of the peanut shells irradiated with an electron-beam. Similarly, electron-beam irradiation substantially increased collagenase and elastase inhibitory activities in the solid treatment. Mutagenicity assay confirmed the stability of toxicity associated with the electron-beam irradiation. In conclusion, electron-beam-irradiated peanut shells could serve as an important by-product with potential applications in functional cosmetic materials.

To develop functional cosmetic material using <i>Rhodiola rosea</i>, the biological activities such as anti-oxidant, anti-inflammatory, astringent, anti-tyrosinase, and anti-elastase activity were investigated with methanol, <i>n</i>-hexane, chloroform, ethyl acetate, n-butanol, and water fractions of <i>R. rosea</i> Root. DPPH and ABTS radical scavenging activities of ethyl acetate fraction were increased in a dosedependent manner; the activities were higher than other fractions. The total phenolic content of ethyl acetate fraction also showed a relatively high value of 500.485±4.848 mgGAE/g. The ethyl acetate fraction also significantly decreased LPS-induced NO production and IL-6 secretion compared with untreated control cells at above 5-100 μg/mL concentrations. The astringent activity of ethyl acetate fraction was 94.31% at a concentration of 500 μg/mL, and the activity of ethyl acetate fraction was similar to that of tannic acid. The mushroom tyrosinase inhibition abilities of hexane, ethyl acetate, and butanol were 10.44%, 17.53%, and 14.55%, respectively, at 100 μg/mL. Furthermore, an elastase inhibition rate showed a relatively high effect at 100 μg/mL, 45.46% of inhibition rate in the ethyl acetate and 45.07% of inhibition rate in the butanol fraction. These results indicate that R. rosea Root would be used as a natural material in the functional cosmetic and beauty-food industries.

Ethyl Gallate Isolated from Castanopsis cuspidata var. sieboldii Branches Inhibits Melanogenesis and Promotes Autophagy in B16F10 Cells

The Castanopsis cuspidata var. sieboldii (CCS) plant grows predominantly in temperate regions of Asian countries, such as South Korea. Research on CCS has so far concentrated on the nutritional analysis, antioxidant activity, and anti-inflammation properties of its branches. However, the isolation of compounds and structural elucidation of effective single molecules remain unexplored, necessitating further exploration of CCS branches. Therefore, this study demonstrates the antioxidant and antimelanogenic activity of a single substance of ethyl gallate (EG) isolated from CCS branch extracts. Notably, the antimelanogenic (whitening) activity of EG extracted from CCS branches remains unexplored. Tyrosinase inhibition, kinetic enzyme assays, and molecular docking studies were conducted using mushroom tyrosinase in order to examine the antioxidant mechanism and antimelanin activity of EG in B16F10 melanoma cells. Nontoxic EG concentrations were found to be below 5 µg/mL. While EG significantly reduced the levels of whitening-associated proteins, p-CREB, and p-PKA, it dose-dependently inhibited the expression of TYR, TRP-1, TRP-2, and transcription factor (MITF). In addition, EG downregulated melanogenetic gene expression and activated autophagy signals. Therefore, EG extracted from CCS branches could serve as a novel functional cosmetic material with antimelanogenic and autophagy-enhancing activity.

Fermented Angelicae tenussimae with Aspergillus oryzae Improves Skin Barrier Properties, Moisturizing, and Anti-Inflammatory Responses.

Angelicae tenussimae root has been used as a traditional medicine in Asia. Recently, anti-melanogenic and anti-photogenic effects of fermented A. tenuissima root (FAT) were identified. However, information about the anti-atopic dermatitis action of FAT is limited. Thus, the purpose of this study is to determine the applicability of FAT to AD by identifying the efficacy of FAT on the skin barrier and inflammatory response, which are the main pathogenesis of AD. Expression levels of skin barrier components and the production of inflammatory mediators in human keratinocyte and mouse macrophage cells were measured by quantitative RT-PCR or ELISA. FAT upregulated the expression of skin barrier components (filaggrin, involucrin, loricurin, SPTLC1) and inhibited the secretion of an inflammatory chemokine TARC in HaCaT cells. Furthermore, it suppressed pro-inflammatory cytokines (IL-6, TNF-α) and nitric oxide production in LPS-induced RAW264.7 cells. In addition, ligustilide increased filaggrin and SPTLC1, and also lowered pro-inflammatory mediators that increased in atopic environments, such as in FAT results. This means that ligustilide, one of the active ingredients derived from FAT, can ameliorate AD, at least in part, by promoting skin barrier formation and downregulating inflammatory mediators. These results suggest that FAT is a potential functional cosmetic material for the care and management of AD.

잇꽃 에탄올 및 열수 추출물의 항노화 기반 항주름효과 비교

Background: The safflower flower (Carthamus tinctorius) contains many bioactive substances and natural pigments. This study aimed to develop a safe and effective functional cosmetic material by comparing the antioxidant and anti-wrinkle effects of C. tinctorius flower ethanol extract (CTE) and hot water extract (CTW).BRMethods and Results: First, the content of hydroxysafflor yellow A in CTE and CTW was determined. Subsequently, a cell-free system was used to examine the 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity of CTE and CTW. Furthermore, the effects of CTE and CTW on elastase and matrix metalloproteinase-1 (MMP-1) were determined through enzymatic analysis or real-time quantitative reverse transcription polymerase chain reaction (qRT-PCR) in human dermal fibroblast (HDF) cells. The wound closure effect of CTW was also measured using the scratching assay in keratinocyte HaCaT cells. The DPPH scavenging activity of CTE was slightly higher than that of CTW. Regarding wrinkle formation, CTE unexpectedly increased MMP-1 and had no effect on elastase activity except at 1,000 ㎍/㎖ of CTE. In contrast, CTW inhibited both elastase activity and MMP-1 expression. CTW also showed a considerable increase in wound closure rate in the scratching assay.BRConclusions: In conclusion, CTW containing the natural pigment hydroxysafflor yellow A is an effective substance for wrinkle treatment and wound healing for skin aging.

The procedures and methods of these experiments are summarized in the following article. In this study, we found that the Bahera, Phyllanthus emblica, Triphala, and Carica papaya extracts had significant effects on whitening and wrinkle improvement, and that the effects of using ethanol-based extracts as the co-solvent were even greater. In other words, extracts of Bahera, Phyllanthus emblica, Triphala and Carica papaya showed antioxidant, whitening, and anti-wrinkle effects, and extracts that used ethanol as a co-solvent showed greater effects. In particular, we found that the optimal concentration of ethanol as a co-solvent maximizes its effectiveness at 70%.

Preventive Effect of M. cochinchinensis on Melanogenesis via Tyrosinase Activity Inhibition and p-PKC Signaling in Melan-A Cell.

Whitening research is of particular interest in the cosmetics market. The main focus of whitening research is on melanogenesis inhibition through tyrosinase activity. The mechanism of melanogenesis is involved with tyrosinase activity and p-PKC signaling. In this study, we used Momordica cochinchinensis (Lour.) spreng, a tropical fruit found throughout Southeast Asia, to investigate the inhibitory effect of melanogenesis. M. cochinchinensis contains a high concentration of polyphenols, flavonoids, and unsaturated fatty acids, which might be related to antioxidant activity. This study aimed to determine whether M. cochinchinensis extracts inhibit melanin synthesis in melan-A cells by inhibiting tyrosinase activity and p-PKC signaling. M. cochinchinensis was divided into pulp and aril and extracted under various conditions, and it was confirmed that all pulp and aril extracts have high contents of both phenols and flavonoids. Melan-A cells were treated with PMA for three days to induce melanin synthesis. After PMA treatment, M. cochinchinensis extracts were added to cultured media in a dose-dependent manner. Melanin contents and MTS were used to determine the amount of melanin in live cells. M. cochinchinensis extracts were evaluated for their effects on tyrosinase activity and p-PKC signaling pathways by Western blotting. It was found that M. cochinchinensis extract treatment decreased the amount of melanin and suppressed p-PKC expression. Additionally, tyrosinase activity was reduced after M. cochinchinensis extract treatment in a dose-dependent manner. Therefore, it was concluded that M. cochinchinensis could be used in antimelanogenesis and functional cosmetic materials to improve whitening.

Metabolite and Elastase Activity Changes in Beach Rose (Rosa rugosa) Fruit and Seeds at Various Stages of Ripeness.

Rose hips are the fruits of the beach rose (Rosa rugosa). To determine the optimal harvest time and to obtain the maximum functional compounds, rose hips at various stages of ripeness (immature, early, mid, and late) were harvested, and the flesh tissue and seeds were separated. The rose hip flesh showed the highest total phenolic content at the mid-ripeness stage (8.45 ± 0.62 mg/g gallic acid equivalent concentration (dry weight)). The early-, mid-, and late-ripeness stages of rose hip flesh did not show significantly different 2,2-diphenyl-1-picrylhydrazyl antioxidant capacities. The elastase inhibitory activity of the 95% ethanol extract from the rose hip seeds was highest at the mid-ripeness stage; however, the elastase inhibitory activity of the rose hip tissue was not significantly different from that of the seeds. Pathway analysis using MetaboAnalyst showed that sucrose, fructose, and glucose gradually increased as the fruit ripened. Ursolic acid was detected in the seeds but not in the flesh. Of the fatty acids, linoleic acid concentrations were highest in rose hip seeds, followed by linolenic acid, oleic acid, and palmitic acid. Fatty acids and ursolic acid might be the active compounds responsible for elastase inhibitory activity and can be utilized as a functional cosmetic material.

Evaluation of Biological Activity of Natural Composite Extracts

To increase the value of using natural plants, we developed antioxidant and anti-aging cosmetic ingredients using Portulaca oleracea(PO) and Agrimonia pilosa Ledeb(APL), known as natural medicinal plants. Both PO and APL were extracted with ethanol as solvents and thecomposite extract was prepared in a 1:1 ratio of PO and APL extracts. The final samples were compared and evaluated based on three extracts, i.e., PO extract, composite extract, and APL extract. The antioxidant effects of these samples were evaluated by measuring DPPH, ABTS, and hydroxyl radical scavenging activity, whereas the anti-aging effects were evaluated via Collagenase and Elastase inhibition rates. In evaluating the antioxidant activity of the APL extract was the highest, whereas that of the composite extract showed inhibitory activity similar to thatof the single extracts but still lower than that of individual extracts. Moreover, the anti-aging effect of the composite extract demonstrated higher inhibitory activity than that of the single tract. The highest inhibition rate was shown in a 2:1 ratio of PO and APL composite. The results to date demonstrate that the composite extract of APL and PO has an efficacy to be used as a functional cosmetic material. With increased interest in anti-aging and well-being around the world, the development of natural materials for herbal medicine is expected to have a considerable effect on the cosmetic industry in future.
