Abstract
The major advantage of the in vitro test is that it is a rapid, objective and cost-effective screening methodology. In vitro tests can provide a formulation tool to identify new fillers that are optimized by combinations of old ones and they can be used to pre-screen protective formulas prior to in vivo testing in humans. Therefore, the accuracy of in vitro SPF measurement is very important. In this study, improvement of application method of samples was tried to improve the accuracy of in vitro SPF measurement. The outer part of Transpore$\^$(R)/ tape was used to apply samples as the substrates and the standard drying time was set at 15 min. The new method, topical applications at light scan areas, results in more accurate and reliable results. This result suggests that more accurate prediction system can be established for in vivo SPF with in vivo SPF measurement.
