Abstract
In the present study, we investigated sun protection factor and antioxidant properties of Parastrephia lepidophyla Cabr., Fabiana squamata Phil., Ephedra chilensis K.Presl., Lampaya medicinalis Phil., Baccharis tola Phil., and Azorella compacta Phil. The ethanol extracts were tested regarding their in vitro free radical scavenger ability and sun protection factor (SPF). Due to its antioxidant and photoprotective properties, B. tola is a promising candidate for use in cosmetic formulations. To evaluate the regenerative capacity of the B. tola extract, the planarian regeneration assay (Dugesia tigrina) was performed. Identification of phenolic compounds in B. tola, was performed by HPLC-ESI-MS/MS. Based on freeze-dried extracts of B. tola, a facial cream and a biphasic lotion with repairing tip action were formulated. These two formulations were evaluated by additional assays including organoleptic tests, measurement of pH, centrifugation and patch test to check a potential hypersensitivity (skin irritation) which can be induced by the products as well as a sensory survey. Stability studies, carried out over 12 months, prove that formulations were stable over time. It can be concluded that both products are innovative and shown solar protection, antioxidant and regenerative properties.
