Abstract

Exposure to solar radiation, particularly its ultraviolet UV component, has a variety of harmful effects on human health. Some of these effects include sunburn cell formations, basal and squamous cell cancers, melanoma, cataracts, photoaging of the skin, and immune suppression. The beneficial photoprotective effects of topical formulations with the extract, Morinda citrifolia, have not been investigated. This present study aims to investigate the potential benefits of M. citrifolia topical application on the dorsal skin of mice, exposed to UVA-UVB light. Using 7 days of treatment, before baseline values and 20 h after UV exposure, the thickness, skin barrier damage TEWL, erythema, and histological alterations were evaluated. The results showed that the formulations containing the extract protected the skin against UV-induced damage.
