Ultraviolet (UV) is thought to induce erythema, sun-burn, photo-toxicity, photo-allergy, photo-aging and sometimes skin tumor. To investigate the photo-protective effects of APB-01 (Amore-Pacific Beauty-01, the mixture of Jaummi-dan and Fujiflavone P10) on UV-induced skin damage, forty of SKH hairless female mice were orally administered with APB-01 or saline fifth a week, and irradiated with UV third a week for up to ten weeks. We examined the relationship between visible changes and skin damage in the dermis and epidermis. In the APB-01 treated group, a better skin and less wrinkles formation were observed when compared to the UV control group. This results demonstrated that oral administration of APB-01 seems to have photo-protective effects on UV-induced skin damage of hairless mice due to an inhibitory effect on collagen breakdown, and the model using hairless mice is very useful to investigate the efficacy of functional beauty foods.

In this study, the anti-oxidant, whitening, and anti-wrinkle effects of Castanea crenata inner shell extracts processed by enzyme treatment and pressurized extraction were investigated. The Castanea crenata inner shell was first hydrolyzed using celluclast, viscozyme, or hemicellulase. Then, it was subjected to pressure extraction for different durations (30, 60, and 120 min). The yields of the Castanea crenata inner shell extracts processed by different enzyme treatments followed by pressurized extraction for different times are in the range of 12.42-29.80%. The total polyphenol, flavonoid, and tannin contents of the C30m (celluclast enzyme and autoclave extracts at 30 min) extract were 15.48, 10.82, and 15.82 g/100 g, respectively. The total sugar content of the H120m(hemicellulase enzyme and autoclave extracts at 120 min) extract is 61.07 g/100 g. The 1,1-diphenyl-2-pycrylhydrazyl (DPPH) and 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radical scavenging activities of the C30m extract at $1,000{\mu}g/mL$ are 89.20, and 81.96%, respectively. The superoxide radical scavenging and ferric-reducing antioxidant power of the C30m extract at $1,000{\mu}g/mL$ are 67.63% and $1,324.79{\mu}M$, respectively. Further, the tyrosinase and elastase inhibition activity of the C30m extract at $1,000{\mu}g/mL$ are 61.32, and 61.06%, respectively. Our results indicate that the Castanea crenata inner shell extracts processed by enzyme treatment followed by pressurized extraction could have beneficial effects on facial skin and they should be considered for use in new functional cosmetics.

Cosmeceuticals products we not the products simply for moisturizing and protecting skin but the ones for encouraging to make improvements on wrinkles and helping to whiten, tan, and protect skin against ultraviolet light. In a broader sense, they refer to products with aiming to maintain healthy condition of skin such that skin troubles could be improved or aging of skin could be delayed. However, cosmeceuticals should not have any side effects because they are applied to the whole body for a long period of time differing from medical products which are used on specific areas for a short time. The number of such cosmeceuticals has increased from 500 in 2001 to 2300 in 2003. In order to develop and broaden the scope of cosmeceuticals, the concept of cosmetics needs to be changed from caring skin to delaying aging of the skin and reviving cells. For this purpose, high-valued materials should be developed through basic researches related to the biological function of skin, in vivo experiment and reaction of skin in response to various stimuli using biotechnologies and bioengineering methods. At the same time, it should be proceeded to develop new nano materials for overcoming skin barriers and transfer matericals for helping to absorb effective substances and maintaining stability.

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.

Carbonylated proteins (CPs) are synthesized by the chemical reaction of basic amino acid residues in proteins with aldehyde compounds yielded by lipid peroxidation. CPs are excited by a range of light from UVA to blue light, and resulted in the generation of superoxide anion radicals ($^{\cdot}O_2{^-}$) by photosensitizing reaction. Then, they CPs induce new protein carbonylation in stratum corneum through ROS generation. Furthermore, the superoxide anion radicals produce CPs in the stratum corneum (SC) through lipid peroxidation and finally affects skin conditions including color and moisture functions. The purpose of this study was to investigate the relationship between the production of stratum corneum carbonylated protein (SCCP) and the skin elasticity. 46 healthy female Koream at the ages of 30 ~ 50 years old were participated in this study for 8 weeks. The skin test was experiment conducted into two groups; placebo group (N = 23) used cream that did not contain active ingredients, and the other group (N = 23) used cream containing the elasticity improving ingredients. Test areas were the crow 's feet and the cheek. Various non-invasive methods were carried out to measure biophysical parameters on human skin indicating that dermis density and skin wrinkle were measured by using DUB scanner and Primos premium, respectively. Skin elasticity were measured using dermal torque meter (DTM310) and balistometer (BLS780). SCCP was assessed in a simple and non-invasive method using skin surface biopsy on the cheek of the subject. The amount of SCCP was determined using image analysis. All measurements were taken at 0, 4 and 8 8week. Results revealed that the amount of CP in SC was reduced when the skin wrinkle and skin elasticity related parameters were improved. This indicates that the correlation between the elasticity improvement and the amount of CP can be used as a anti-aging indicator and applicable to the skin clinical test for the measurement of skin aging in the future.

The possibility of usage as cosmetic resource of the mycelial culture broth of P. japonica in the mixture of cucumber and grape extracts was investigated. In the effect of collagen synthesis promotion in human fibroblast cells, the culture broth of P. japonica of 0.1, 0.5 and 1.0% concentration increased the amount of collagen synthesis than that of control cells. The culture broth increased the SOD activity in the concentration dependant manner of 0.01% to 1.0% in the antioxydation activity test. About 90% of superoxide radical was eliminated by 0.5% concentration of the culture supernatant in the antioxydation test. Anticoagulant quercetin in the course of mycelial growth in the mixture of cucumber and grape extract was accumulated to 15 folds than that of pre-culture. In the skin safety test of the culture broth, there is no any skin damage signal in the tested 30 people. Taken together, we concluded that the culture broth of P. japonica in the mixture of grape and cucumber extracts can be used as a cosmetic resource.
