Abstract

Recent research has revealed that hydrolyzed collagen peptides have beneficial effects in various diseases such as osteoarthritis and human rheumatoid arthritis and also play a protective role in skin by improving the activity of antioxidants. In this study, we investigated the effects of a novel mixture (AP-CPM01) containing collagen peptides and elastin peptides on photoaged hairless mice skin both in vivo and in vitro. To evaluate the effects of AP-CPM01 on UVBinduced skin wrinkle formation in vivo, the hairless mice were exposed to UVB irradiation and orally administered the AP-CPM01 at 333 mg/kg per day for 10 weeks. The effects on skin appearance and epidermal thickness were measured using bioengineering and histochemical methods. In addition, the influence of AP-CPM01 on collagen metabolism in human skin fibroblasts was also investigated. The skin of mice in the AP-CPM01 treated group had better appearance and less wrinkling than that of mice in the control group. In the human fibroblast cells, the amount of de novo procollagen synthesis was increased after AP-CPM01 treatment, reflecting that AP-CPM01 can induce de novo procollagen synthesis and reduce UVB-induced skin wrinkle formation. These results suggest that AP-CPM01 is a potent candidate for antiphotoaging functions.

In vivo에서 10주간의 UV처리에 의해 유발되는 피부 손상에 대한 콜라겐 펩타이드 혼합물(AP-CPM01)의 보호 효능을 관찰한결과, UV에 의해 유도되는 주름의 증가와 탄력 저하 및 비정상적인 각질 세포의 증식에 의한 피부 두께의 증가가 혼합물의 섭취에 의해 개선됨을 확인하여, 콜라겐 펩타이드 혼합물이 UV에 의한 피부 손상을 방어하고, 피부 기능이 정상적으로 작용할 수 있도록 도움을 주는 것을 알 수 있었다. 콜라겐 펩타이드 혼합물의 피부 보호 작용 기전을 살펴보기 위하여 사람 섬유아세포를 이용하여 콜라겐 펩타이드 혼합물의 작용을 평가한 결과, 콜라겐 펩타이드와 엘라스틴 단백질은 procollagen 발현을 농도 의존적으로 증가시키고 시너지 효과가 있음을 확인하였으며, 이를 통하여 콜라겐 펩타이드 혼합물이 광노화에 의해 유발되는 피부 진피층의 손상을 회복 혹은 보호하는 효능이 있음을 알 수 있었다. 이상의 결과로부터 콜라겐 펩타이드 혼합물(AP-CPM01)이 광노화 보호 또는 피부 개선 효능을 갖는 새로운 미용 식품 소재로써 이용 가능성이 높음을 알 수 있다.
