Executive Summary
UVA TESTING METHODOLOGY: IN VIVO/IN VITRO COMBINATION METHOD SUGGESTED by Nicholas Lowe, MD, UCLA School of Medicine, as a testing standard to predict the protective effect of LIVA sunscreens. Speaking at a May 12 public workshop sponsored by FDA on UVA testing methods, Lowe advised FDA to "decide on an appropriate in vivo test which will give us performance data in humans [and] will tell us the characteristics of a specific formulation." He recommended that the in vivo test be used in combination with an in vitro test which will supply "accurate spectral absorbance data."
