Previously, we reported LVH peptiede derived from Aurelia aurita as cosmecetuticals with anti-winkle activity. In this study, we synthesized pal-LVH using palmitic acid to enhance skin permeability of LVH and examined the effects as cosmeceuticals of pal-LVH. To evaluate these effects, we performed cell toxicity, wound healing, and patch test for skin irritation with LVH and pal-LVH and compared these results for their effects. As a result. pal-LVH was not showed in cytotoxicity and allergenic effect like as LVH. Besides, pal-LVH had almost same excellent anti-ageing properties in high concentration and anti-winkle effect in low concentrationwas as LVH. These results suggested synthesis of palimitic acid and LVH did not affect any functions as cosmeceuticals with increasing skin permeability. Therefore, pal-LVH can be adaptable as new cosmecetuticals with anti-winkle and anti-ageing materials and applied in the development of medicine through various convergence study.

This study was conducted to investigate the anti-oxydant and anti-winkle efficacy as cosmetics ingredient of Lysimachia christinae Hance. Recently, the study of wrinkle improvement of natural products has received continuous interest. so we looked at relationship between reactive oxygen species (ROS) generation and pro-collagen synthesis and matrix metalloproteinases (MMPs) through this study. L. christinae Hance were extracted with 70% ethanol (LcHE) and distilled water (LcHW), respectively, and the experiment was conducted. LcHE had better ROS inhibition effect than LcHW and showed no toxicity up to 250 ㎍/mL concentration as a result of MTT assay in HaCaT cells, so we selected LcHE and conducted the wrinkle improvement material study. We confirmed that the synthesis of type-1 pro-collagen reduced by UVB is activated through pro-collagen synthesis assay. we confirmed that LcHE inhibited the increase in MMP-1 -3 -9 of MMPs induced by UVB in skin cells through western blot and we also performed real-time PCR to confirm the effect of the extract with dependence of concentration at mRNA levels. Therefore, it is expected that Lysimachia christinae Hance is used as a natural material for cosmetics that can effectively prevent wrinkles and skin aging by UVB.

Astradalus membranaceus root extract (ARE) contains saponins, flavonoids, and their glycosides. Two flavonoids, calycosin and formononetin, were predominant constituents with the different amount by diverse extraction conditions. ARE showed the anti-oxidative activities, inhibited tyrosinase activity, and increased type I procollagen expression in proportion to calycosin and formononetin contents. The clinical study also showed that skin wrinkles were significantly reduced in the test group treated with a cream formulation containging 0.1% ARE compared with a group treated with a cream formulation without 0.1% ARE (p < 0.05). These results suggest that ARE may have potential as an anti-aging ingredient in cosmetics.

In order to develop anti-wrinkle agent, we measured the anti-oxidative activity of gallic acid (GA) from Paeonia suffruticosa Andrews and investigated its cytotoxicity in HaCaT cells and then investigated its effect on tumor necrosis factor alpha (TNF-${\alpha}$)-induced matrix metalloproteinase-1 (MMP-1) mRNA, protein expressions and secretion in same cells. GA showed anti-oxidative activity with $IC_{50}$ of 30 ${\mu}g/mL$ and its activity was higher than that of butylated hydroxyanisol (BHA). GA showed weak cytotoxicity with high concentration (200 ${\mu}g/mL$) in HaCaT cells. MMP-1 mRNA, protein expression and secretion induced by tumor necrosis factor alpha (TNF-${\alpha}$) in HaCaT cells were significantly decreased by treatment of GA with dose-dependent manner(p<0.05). Therefore, our findings suggest that GA can be useful as an active ingredient for cosmeceuticals of anti-wrinkle effects.

In this study, Camellia sinensis Leaf cultivated in Boseong was extracted by vacuum distillation and hydrothermal extraction methods, and we performed in vitro experiments such as antioxidant, anti-wrinkle, whitening, and antibacterial activity test and HPLC analysis. Wrinkle improvement (elastase inhibition assay) and whitening effect (mushroom tyrosinase inhibition assay) of Boseong vacuum distilled extract have excellent results and IC50 values of vacuum distillation extract was measured at a lower concentration than that of the hydrothermal extract. The antioxidant activity of the Boseong hydrothermal extract was excellently measured in DPPH radical and ABTS+ radical scavenging activity, SOD-like activity, and total polyphenol content. In the antibacterial experiment, the Boseong hydrothermal extract formed a clear zone for the Staphylococcus aureus and Cutibacterium acnes strain. As a result of HPLC analysis, EGCG and caffeine in the hydrothermal extract were 40.29 mg/g, 9.94 mg/g respectively, and caffeine in the vacuum distilled extract was 3.40 mg/g. Therefore, we examined that Boseong Camellia sinensis vacuum distilled extract has excellent anti-wrinkle and whitening effect, and its hydrothermal extract has good antioxidant and antibacterial efficacy.

ln this study, natural extracts extracted from cypress sapiens, a natural material, were investigated as materials that could protect skin aging caused by ultraviolet rays, and experiments were conducted on the synthesis of filaggrins that make up the natural moisturizing factor of the skin, the synthesis of pro-colagen, a fibrous protein, which plays an important role in moisturizing the dermis, and elastin, which is an enzyme that decomposes collagen. As a result, cypress ethanol extract (COE) was a dependent inhibitor to collagenase and elastase, inhibiting the synthesis of filaggrin and the expression of MMP-1 for exfoliated cells damaged by ultraviolet rays. Therefore, it is estimated that ethanol extract will have the effect of delaying wrinkles and as a functional cosmetic material that inhibits skin aging convergence. Based on this study, we would like to further study the mechanism of the synthesis of filaggrin on the suppression of expression of MMP, which is the anti-wrinkle effect.
