Executive Summary
APP SUNSCREEN UVA TEST METHOD PROVIDES "BENCHMARK" DESCRIPTION of how a sunscreen protects against UVA light, Schering-Plough HealthCare Products researcher Patricia Agin, PhD, said at a May 12 FDA workshop on UVA testing. In response to FDA's concerns that the UVA protection percentage (APP) in vitro test method may overestimate product efficacy, Agin explained that "APP is a benchmark which describes how [a sunscreen] performs using the erythemal action spectrum and full solar UVA" light.
