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.

Sphingolipid production was investigated through Ganoderma lucidum-submerged cultivation. Crude sphingolipid obtained from G. lucidum was purified by methanol precipitation, Dowex AG DW-X8 (H+ form) cation exchange chromatography, and preparative thin layer chromatography, Structure and functionalities of purified sphingolipid were elucidated including cutaneous hydration effect. Possibility of use as cosmetics material and new biomaterial was explored. Production was 0.4 g/L at 1% yield. Purified sphingolipid was identified as D-ribo-1,3,4-trihydroxy-2-aminoocta decan through UV/VIS, FT-IR, and $^1H-NMR$. Sphingolipids increased skinmate value for cutaneous hydration effect by 20% at $500\;{\mu}g/mL$ and decreased skin roughness at $100\;{\mu}g/mL$. Results suggest shingolipids from G. lucidum are effective for cutaneous hydration and improvement of skin roughness.

In order to discover physiologically active substance, we investigated a powder obtained by processing of Opuntia ficus-indica var. saboten Makino trunk. The powder was treated by sulfuric acid and then extracted by several solvents such as methanol, methylene chloride, ethanol etc. Among them, the best antimicrobial activity was showed by methylene chloride extract. To identify materials exhibiting physiological activation, the acid hydrolyzed extract was separated by 7 fractions through preparative silica gel TLC. The effective fraction exhibiting the best broad antimicrobial activity was identified, named as MBT-01108. From structural analysis of the products extracted to acid hydrolysis, a compound exhibiting the antimicrobial activities is identified to levulinic acid. Levulinic acid isolated from Opuntia ficus-indica var. saboten Makino may be applicable as a natural preservative of food or cosmetic and for prevention of bacterial diseases, an ingredient of acne, ageing and whitening cosmetics and an antimicrobial agent.

The ecofriendly yellow ocher is used in the manufacturing of cosmetics, construction, and food packaging. The polyethylene terephthalate (PET) used for manufacturing food containers has a microporous structure that causes aeration. Hydrophilic yellow ocher may be applied to hydrophobic PET by surface modification to overcome this issue. The aim of this study is to fabricate a yellow ocher polystyrene hybrid structure in the form of nanoparticles using an optimizing molar ratio of styrene, divinylbenzene, and potassium peroxodisulfate for use in emulsion polymerization. The polymerization was conducted in a yellow ocher suspension that was prepared by dispersing mechanically ground yellow ocher in DI water. The prepared hybrid structure was measured using scanning electron microscopy, energy dispersive X-ray spectroscopy, and X-ray diffraction. The measurement revealed the spherical morphology and Si component that resulted from the yellow ocher in the polystyrene particles. We expect that this hybrid structure would be used as platform material to minimize aeration in PET.

Various herbal medicinal extracts were examined for the development of cosmetic products with anti-oxidative and anti-wrinkle activity. First, total polyphenol contents and DPPH radical scavenging activities of herbal medicinal extracts were measured. Most herbal samples, except for DW extracts of Portulaca oleracea, Caesalpinia sappan, Taraxacum platycarpum, Carthamus tinctorius, and 70% EtOH extracts of Taraxacum platycarpum and Carthamus tinctorius, showed DPPH radical scavenging activity over 80% at a concentration of $400{\mu}g/m{\ell}$. SOD-like antioxidant activity of DW extracts of Syzygium aromaticum, DW extracts of Eriobtrya japonica and 70% EtOH extracts of Sophora japonica was measured as 40%, 35% and 80%, respectively at a dry matter concentration of $50{\mu}g/m{\ell}$. In elastase inhibition assay, DW extracts of Lycium chinense ($50{\mu}g/m{\ell}$) and 70% EtOH extracts of Areca catechu ($50{\mu}g/m{\ell}$) showed 50% and 40% of inhibition, respectively. At a concentration of $1.250{\mu}g/m{\ell}$, DW extracts of Lycium chinense and 70% EtOH extracts of Areca catechu showed 10% and 30% of collagenase inhibition, respectively. Skin and lotion samples were prepared using the two herbal extracts of high anti-wrinkle activity: Lycium chinense extract and Areca catechu extract. The storage stability of skin and lotion containing each of the selected herbal extracts was evaluated. pH and viscosity were used as stability indicators for the stability test under different storage temperatures and freeze-thaw cycle conditions. The skin and lotion containing each of DW extract of Lycium chinense and 70% EtOH extract of Areca catechu was showed high pH and viscosity stability. The skin and lotion containing DW extracts of Lycium chinense showed relatively higher stability than the skin and lotion containing 70% EtOH extract of Areca catechu, at cycle chamber and freeze-thaw conditions. In summary, these results indicated that cosmetics containing DW extract of Lycium chinense were relatively stable, and this herbal extract could be used as a stable functional cosmetic material.

Most neurodegenerative diseases are known to be influenced by oxidative stress. We investigated the anti-oxidative activity of the concentrate of fermented wild ginseng root culture (HLJG0701) containing ginsenosides Rg5 and Rk1. HLJG0701 showed effective DPPH and ABTS radical scavenging ability ($IC_{50}$: 16- and 4-fold dilution, respectively) and was inhibited dose-dependently by the $FeSO_4$-induced lipid peroxidation group (8- and 4-fold dilution: 2.3 and 1.5 nM, respectively). In MTT and LDH assays, 8-, 16-, 32- and 64-fold diluted HLJG0701 significantly increased cell viability by 70, 53, 35, and 26%, respectively. LDH released by HLJG0701 was reduced 1.3-fold with 8-fold diluted HLJG0701 compared to the $H_2O_2$-treated control. In addition, the inhibitory effect of HLJG0701 on oxidative stress in PC12 cells was confirmed by DCF-DA analysis (16-, 4-fold diluted HLJG0701: 50 and 68% ROS inhibition, respectively), TBARS (16- and 4-fold diluted HLJG0701: 50.7 and 46.5% inhibition, respectively), GPx (16- and 4-fold diluted HLJG0701: 133.3 and 227.3% release, respectively), and SOD analysis (16- and 4-fold diluted HLJG0701: 118.2 and 218.2% release, respectively). These results suggested that HLJG0701 protects neuronal cells by its anti-oxidative effects and hence can be a potential preventive material against neurodegenerative diseases.

The antioxidant, whitening, and anti-wrinkle activity of Spirodela polyrhiza extracts and fractions were evaluated to determine its efficacy as a functional cosmetic material. 1,1-diphenyl-2-picrylhydrazyl and 2,2'-azinobis-3-ethylbenzothiazoline-6-sulfonic acid radical scavenging activities were 44.2 and 74.3%, respectively, at 100 ㎍/mL of SE-E (the ethyl acetate fraction of 70% ethanol extract). To measure anti-wrinkle effects, procollagen biosynthesis and matrix metalloproteinase-1 (MMP-1) inhibition activity were determined. At 25 ㎍/mL of SE (70% ethanol extract), the biosynthesis activity was 48.5%, and SE-E showed the best activity (57.8%) at the same concentration. MMP-1 inhibition activity of SE and SE-E was 13.4 and 28.5%, respectively, at 25 ig/mL. Finally, the inhibition of cellular melanin synthesis and cellular tyrosinase were measured to determine the whitening effect; at 25 ㎍/mL, the inhibition activities of SE were 9.6 and 13.8%, respectively, and those for SE-E were 15.4 and 22.0%, respectively. Our results confirmed the possibility of SE and SE-E as effective functional materials. Further research investigating the antimicrobial, anti-inflammatory, and anticancer activities of S. polyrhiza is necessary to confirm its potential use in the food, cosmetics, and drug industries.

This study examined the effects of polyphenols in grape pruning stem extracts (GPSE) using grape stems discarded after harvest. The inhibitory effects on allergy, proliferation, and apoptosis in UVB-induced HR-1 hairless mice were analyzed. The applicability as a material for functional food and functional cosmetics was evaluated. The contents of the active ingredients of GPSE were analyzed by HPLC. After UVB irradiation on the dermis of HR-1 hairless mice, the number of mast cells was determined by toluidine blue staining to confirm that the skin allergic reaction was caused by GPSE. The results were similar to the normal group in the group applied GPSE, and there was no allergic reaction in the GPSE application group and a significant decreased compared to the sun cream control. PCNA immunohistochemical staining of the epidermal proliferation factor had an inhibitory effect on epidermal epithelial cell proliferation in all concentrations of GPSE and serum base mixture as an average of 42% compared to the control group. The mixture of GPSE and serum base suppressed the apoptosis inhibition rate by 27% on average compared to the control. These results confirmed the inhibitory effects GPSE on the allergic, proliferation, and apoptosis activities by with a serum base on UVB-induced skin damage. GPSE is a functional ingredient with potential skin protection effects, and has a high utilization as an ingredient for functional cosmetics.
