Chronic exposure to UVB irradiation can caused premature skin aging (photoaging), as it can trigger the production of ROS and initiate both oxidative stress in cell membrane and affect the molecular pathway. This paper figured out the potential of oral and topical administration of C. asiatica extract on hairless rats skin tissue exposed by UVB based on expression of TGF-β1, MMP-1 and MDA dermis. A total of 30 male-hairless rats (Rattus novergicus) divided into 6 experimental groups, exposed by UVB with total dose 840 mJ/cm2 for four weeks. Topical gel therapy administered twice a day, 20 minutes before and 4 hours after irradiation. Oral therapy administered once a day before irradiation. Expression of TGF-β1, MMP-1 and MDA dermis observed by immunohistochemistry. The result showed that oral and topical therapy of C. asiatica extract was capable of inhibiting the increase of MMP-1 and MDA expression and the decrease of TGF- β1 significantly (p |
