Abstract
UV irradiation can cause cutaneous damage that may be specific according to the wavelength of UV rays. For example, damage from UVB irradiation manifests itself in the form of sunburn cells and enhancement of the expression of p53, while damage from UVA exposure results in an increase in the expression of vimentin. These reactions to UV irradiation were used in this work to evaluate the photoprotective capacities of two sunblock preparations that were applied to the surface of the skin. One sunblock preparation is a UVB absorber containing the coastal plant of Melaleuca cajuputi essential oil and titanium oxide (TiO2) exclusively. The other sunblock preparation is a conventional sunblock containing oxybenzone as comparison. Result obtained for UV-Vis test was observed that the new formulation derived showed good absorption and exhibit high potential to be further develop as sunscreen in cosmeceutical applications
