Study of the persistence of the anti-inflammatory effect observed after application of preparations containing organic ultraviolet filters.
Int. J. Pharm. 476(1-2) , 160-3, (2015) Given that previous studies have highlighted the anti-inflammatory nature, which is influenced by UV radiation, of a certain number of ultraviolet filters currently used in Europe, it seemed interesting to evaluate the persistence of this type of effect. The ... |
