The aim of the present experimental study is the incorporation of an extract of the Porphyra Umbilicalis seaweed, which contains mycosporin derivatives (MAAs) in a sunscreen formulation, in combination with organic filters, in order to study its influence on the SPF and UVA PF. The results obtained from the in vitro SPF and UVA PF measurements as well as the physicochemical stability control of the new formulas, contribute to the effort for the partial replacement of organic sunscreen filters in sunscreen compositions.
