Abstract
The problems inherent in testing the protective efficacy of sunscreens are reviewed. Of primary importance are: the spectral power distribution of the test light source, which should simulate the ultraviolet radiation of midlatitude, midsummer sunlight; definition of minimal erythema of skin, and equilibration of light source and filters prior to testing.
