Abstract

To investigate the effect of Panax ginseng C.A. Meyer extract (Ginseol K-b1), on skin functionality, we evaluated skin appearance and properties, such as wrinkle formation, skin moisture content, and skin elasticity in the skin of hairless mice damaged by UV irradiation. In addition, the effect of Ginseol K-b1 on collagen synthesis in human dermal fibroblasts was investigated. Female hairless mice were orally administered Ginseol K-b1 for 10 weeks with UV irradiation. Wrinkle formation in the Ginseol K-b1-treated group was significantly suppressed compared to the UV-irradiated group. Skin properties, including skin moisture content and elasticity, of the Ginseol K-b1-treated group were better than those of the control group. In the human fibroblast cells, Ginseol K-b1 treatment enhanced cell proliferation and significantly stimulated collagen synthesis. These results suggest that Ginseol K-b1 is a potent ingredient with anti-aging effects.

$In$ $vivo$ 동물 모델에서 10주간의 자외선 조사에 의해 유발되는 피부 손상 및 사람 피부섬유아세포에 Ginseol K-b1이 미치는 영향을 확인하고자 하였으며, 그 연구결과를 요약하면 아래와 같다. 1. 반복적인 UV 조사에 의해 7주 후부터 hairless mice의 주름이 육안으로 확인되며, Ginseol K-b1 0.0625%(w/w) 농도로 함유한 사료의 10주간 섭취는 UV 조사군에 비해 유의적 ($p$<0.05)으로 주름 생성의 정도를 억제시켰다. 피부 표피 두께 역시 Ginseol K-b1섭취군은 UV 조사군에 비해 유의적으로 작았다. 2. UV 조사는피부 수분 함량 및 탄력도를 감소시키며, Ginseol K-b1의 섭취는 표피 수분량 저하 및 탄력 감소를 유의적($p$<0.05)으로 억제하였다. 3. Ginseol K-b1은 사람 섬유아세포의 세포 증식을 유의적($p$<0.001)으로 촉진시켰으며, 저농도(1.56~6.25 ${\mu}g/mL$)에서 콜라겐 생성량을 유의적으로 증가시켰다. 이상의 결과에서 Ginseol K-b1은 피부 섬유아세포의 증식 및 콜라겐 생성을 촉진함으로써 피부 표면의 주름 생성 및 탄력 저하 억제를 통해 UV로 인한 피부 손상으로부터 피부를 보호하는 효과가 있는 것으로 보이며, 이는 화장품이 아닌 먹는 피부 미용 소재로서의 가능성이 높음을 평가할 수 있다. 그러나 세포내 신호 전달 체계에 대한 추가적인 연구가 이루어져 기작에 대한 명확한 설명이 필요할 것으로 사료된다.
