The present invention is directed to methods and compositions capable of scavenging reactive free radicals for therapeutically or prophylactically treating disorders associated with free radical-induced damage, said compositions comprising an amount of 2-(3-chlorophenylamino) phenylacetic acid (23CPPA) or a pharmaceutically acceptable salt thereof that interacts with free radicals generated by cellular metabolism or ultraviolet radiation. In some embodiments, the composition comprises pharmaceutically or cosmetically acceptable adjuncts. The present invention further provides one or more kits that are useful for delaying, treating or preventing the consequences of aging and free radical damage on the condition or appearance of the skin.
