This study focused on the preparation and characterization of anti-wrinkle peptides from the salted and fermented shrimp (Acetes japonicus) inoculated with Salinivibrio cibaria BAO-01 (SFSC). The results showed the proximate composition of SFSC to be 9.23% water, 75.32% protein, 0.23% fat, and 13.3 mg/g ash. Interestingly, the S. cibaria fermentation significantly increased the amount of methionine, leucine, and arginine. The in vitro antioxidant activity was assayed by the diphenylpicrylhydrazyl method and its IC₅₀ value was found to be 43.02±2.84 ㎍/mL. It was observed to inhibit the activity of elastase, tyrosinase, collagenase, and hyaluronidase. The IC₅₀ values of SFSC were 182.75±12.38 ㎍/mL for anti-elastase activity, 186.78±7.95 ㎍/mL for anti-tyrosinase activity, 444.4±34.81 ㎍/mL for anti-collagenase activity, and 1447.95±28.92 ㎍/mL for anti-hyaluronidase activity. These results suggest that salted and fermented shrimp has strong potential for the development of nutricosmetic products.

This study examined the effect of 3,4-dihydroxytoluene (DHT) on UVB-induced photoaging and determined its molecular mechanisms, using HaCaT human keratinocytes and SKH-1 hairless mice. DHT suppressed UVB-induced matrix metalloproteinase-1 (MMP-1) expression in HaCaT cells. In vivo data from mouse skin supported that DHT decreased UVB-induced wrinkle formation, epidermal thickness, and matrix metalloproteinase-13 (MMP-13) expression. DHT appeared to exert its anti-aging effects by suppressing UVB-induced Raf-1 kinase activity and subsequent attenuation of UVB-induced phosphorylation of MEK, ERK, and p90RSK in HaCaT cells. In vitro and in vivo pull-down assays revealed that DHT bound with Raf-1 in ATP-noncompetitive manner. Overall, DHT appears to anti-photoaging effects in vitro and in vivo through the suppression of Raf-1 kinase activity and may have potential as a treatment for the prevention of skin aging.

Forsythia fructus has been shown to have antioxidative, anti-inflammatory, antibacterial, anti-aging and whitening effects. This work was carried out to investigate the anti-aging effects of Forsythia viridissima-prescription extracts (Yeongyoseungma-tang, Gamiyeongyoseungma-tang, Hoechunyangkyeok-san) on skin. Skin anti-aging effect of Forsythia viridissima-prescription extracts (Yeongyoseungma-tang, Gamiyeongyoseungma-tang, Hoechunyangkyeok-san) was evaluated by using antioxidant assay, anti-glycation activity, inhibitory effect of tyrosinase activity, expression of type I procollagen and UVA-induced matrix metalloproteinase-1 on HS68 cells, and reduction of ${\alpha}$-MSH-induced melanin on B16F1 cells. Forsythia viridissima-prescription extracts showed anti-oxidative and anti-glycation activity. The pectinex hydrolysed extract from Yeongyoseungma-tang 75% EtOH extract and Gamiyeongyoseungma-tang 75% EtOH extract increased the type I procollagen synthesis, and decreased the UVA-induced MMP-1 expression on HS68 cells. The pectinex hydrolysed extracts of Hoechunyangkyeok-san 75% EtOH extract had the inhibitory effect of melanin synthesis on B16F1 cells. Based on these results, we suggest that Forsythia viridissima-prescription extracts may be useful as a potential source of functional anti-aging cosmetics.

In the aged skin especially in the face and eyelid, deep and slight wrinkles are one of the remarkable phenomena of aging and the cause of wrinkle is various. Among the cause of wrinkles an oxidative stress plays an important roles in wrinkle formation process. It caused the lipid peroxidation of cell membrane, the increase of the MMPs(MatrixMetalloProteinase) gene expression and cellular DNA damage. These ROS induced materials may cause the degradation of collagen matrix system in the dermis and cause the formation of skin wrinkle. So, it is very important for protecting skin wrinkle formation to regulate ROS activity. In this study, we developed one active ingredient having multi functional activities such as activation of collagen synthesis, inhibition of MMPs activity, lipid peroxidation and free radical scavenging activity and inhibition of free radical induced DNA damage in vitro. Pericarpium castaneae extracts showed collagen synthesis increase in Normal Human Fibroblast and the inhibition of elastase activity (IC$\_$50/ of Elastase: 43.9$\mu\textrm{g}$/㎖). It showed also anti-oxidative activity (IC$\_$50/ : 48$\mu\textrm{g}$/㎖) and free radical scavenging activity(IC$\_$50/: 7.6$\mu\textrm{g}$/㎖). Conclusively, Pericarpium castaneae extracts may be used as an ingredient for new anti-wrinkle cosmetics.

Advanced glycation end products (AGEs) are final products formed by glycation reaction between reducing sugars and proteins, lipids or nucleic acids. These AGEs are related to progress of skin aging. In this study, we evaluate anti-aging activity of Defatted Torreya nucifera seed extract (DTSE) through antioxidant, anti-glycation, anti-elastase and inhibitory and breaking activity on the cross-linking of AGEs to collagen assay. Results showed that DTSE contained polyphenols and flavonoids. The $IC_{50}$ values of 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radical scavenging activity were $16.4{\mu}g$ (Dried materials, DM)/mL and $16.7{\mu}g\;DM/mL$, respectively. DTSE also inhibited the formation of AGEs, elastase activity and cross-linking of AGEs to collagen as well as broke existing cross-linking of AGEs to collagen in a dose-dependent manner. Consequently, our findings suggest that DTSE could be useful as a cosmetic material with anti-aging activity.

Selaginella tamariscina with the popular Korean name Keoun Back, is a traditional medicinal plant for therapy of advanced cancer patients in the Orient. In this study, we evaluated anti-aging activity of S. tamariscina using processed technology and investigated diverse biological activities of processed S. tamariscina (PST) as an anti-aging ingredient of cosmetics. PST, heated with sand, used to different purpose compared with origin in medicine. PST raises total phenol concentration and enhances the DPPH radical scavenging activity. For testing intracellular ROS scavenging activity, the cultured human dermal fibroblasts were analyzed by increase in dichlorofluorescein (DCF) fluorescence upon exposure to UVB $20 mJ/cm^2$ after treatment of PST. UVA-induced MMP-1 expression in human dermal fibroblasts was reduced in a dose-dependent manner by PST. Taken together, 4hese results suggest that PST may act as an anti-aging agent by preventing the skin cell from damage induced by UV irradiation, and imply that PST may be useful as a new ingredient for anti-aging cosmetics.
