The use of bee venom (Apis mellifera L., BV) occasionally causes side effects such as inflammation and allergic reactions in the recipients. Several case reports also suggested the treatment of BV has some limitations in its clinical uses, due to the occurrence of dermal necrosis and anaphylatic reactions. It is generally understood that bee venom allergy is mainly the result of its allergic component, phospholipase A2 (PLA2). The present study was aimed to generate PLA2-free bee venom (PBV) and evaluate its efficacy as skin care and cosmetic preparation, comparing with original bee venom (BV). Our results showed that both BV and PBV exhibited significant protective effects in UVB-irradiated human keratinocyte (HaCaT) and human dermal fibroblast (HDF) cells and they also induced type I collagen synthesis in UVB-irradiated HDF cells except BV at 3 μg/ml. Furthermore, BV and PBV showed the inhibition of UVB-stimulated matrix metalloproteinase-1 (MMP-1), a major collagen degrading enzyme in skin. However, BV, unlike PBV, exhibited strong cytotoxicities in skin cells (both HaCaT and HDF) at its working concentrations of anti-wrinkle effect. The underlying cell signaling mechanisms of anti-wrinkle effects of BV and PBV were demonstrated by the activation of ERK1/2, and p38. Conclusively, PBV appears to be the bee venom of choice with less cytotoxicity and higher efficacy on UVB-irradiated skin cells in comparison with original bee venom (BV). Therefore, PBV can better be used as a cosmetic ingredient exhibiting excellent anti-wrinkle effect against photoaging than original BV.

This study was to investigate anti-skin wrinkle effect of Agastache rugosa Kentz extracts by extraction processes.In the comparison of the effect of the solvent extraction, the extracts by 70% ethanol (EE) showed better biological activitiesthat those by hot water. Therefore, further fermented Agastache rugosa was applied to 70% ethanol extraction process(FEE). FEE showed higher DPPH scavenging activity of 62.98% than EE’s 62.71% at 1.0㎎/㎖, but there was no significant.Elastase inhibition was measured 23.0% from FEE at 1.0㎎/㎖. Cytotoxicity showed the highest 16.26% from FEE, thisvalue is safe in the cell experiment. Collagen production showed 113.1ng/㎖ from FEE, on the other hand EE was measured77.4ng/㎖ in adding 1.0㎎/㎖. MMP-1 production was observed 1398pg/㎖ from FEE and EE was measured1632pg/㎖. These results were found the highest antioxidant and anti-wrinkle effect. As a result, it was also confirmed thatanti-skin wrinkle activities of the Agastache rugosa Kentz extract was correlated with anti-oxidant activities.

콜라겐은 포유동물의 가장 풍부한 동물성 단백질로, 전체 단백질의 약 30 %를 차지하며, 결합 조직에 존재하며 대부분의 장기의 구조적 지지에 기여한다. Tripeptide (glycine-proline-hydroxyproline; INCI name Tripeptide-29)는 collagen type I의 주성분이며, palmitoyl tripeptide (palmitoyl-glycine-proline-hydroxyproline; INCI name Palmitoyl Tripeptide-29)는 콜라겐의 합성을 촉진하는 항노화 물질로서 디자인된 합성소재이다. 합성된 펩타이드 유도체는 HPLC를 이용하여 분석하였다. in vitro test를 통하여 콜라겐합성과 섬유아세포 증식 효능을 확인하였고, 비침습적 기기를 사용하여 피검자에 대한 8주간의 적용결과 피부주름과 탄력의 상당한 개선을 확인하였다. Palmitoyl tripeptide는 우수한 항노화 효능을 갖는 화장품 소재로 사료된다.
