Ultraviolet radiation is a major cause of photoaging, characterized by wrinkle formation and skin dehydration. Mojaban (Sargassum fulvellum), belonging to the brown algae of the Sargassaceae family, exerts anti-inflammatory, antioxidant, and anti-atopic activities. Particularly, Mojaban extract alle...

광노화의 주요 원인은? | 자외선(Ultraviolet radiation)은 피부 주름 형성과 피부 건조를 특징으로 하는 광노화의 주요 원인이다. 모자반과(Sargassaceae)에 속하는 모자반(Sargassum fulvellum)은 항염증, 항산화, 항아토피 활성을 갖고 있다. | |
모자반은 어떤 효능을 가지고 있나? | 자외선(Ultraviolet radiation)은 피부 주름 형성과 피부 건조를 특징으로 하는 광노화의 주요 원인이다. 모자반과(Sargassaceae)에 속하는 모자반(Sargassum fulvellum)은 항염증, 항산화, 항아토피 활성을 갖고 있다. 특히, 모자반은 인간 각질세포(keratinocyte)와 실험동물의 피부에서 UVB에 의한 염증 반응을 완화시키는 것으로 보고되었다. | |
본 연구에서는 모자반 추출물의 광노화 억제 효과를 확인하기 위해 어떤 연구과정을 수행했나? | 그러나, 현재까지 모자반 추출물의 광노화 억제 효과에 대해서는 보고된 바가 없다. 본 연구에서는 광노화를 유도하기 위하여 UVB를 SKH-1 무모 마우스의 등 부분에 8주간 처리하였으며, 동시에 모자반 추출물을 300 mg/kg의 농도로 매일 경구 투여하였다. 현상학적으로, 모자반 추출물은 주름 형성, 홍반 및 피부 두께를 감소시켰으며, 피부 탄력을 증가시켰다. |
