In vitro SPF measurements are challenged by reproducibility, repeatability and correlation with in vivo values. Here, the authors assess sunscreen adhesion to the test substrate support, since poor adhesion produces bad results. Surface substrates are characterized by functional group, charge, wettability and surface morphology. Eight w/o and o/w emulsions also are tested. Results indicate an ideal in vitro test substrate does not exist.
