Comparison of UVA protection afforded by high sun protection factor sunscreens.

Division of Dermatology, University of Montreal Hospital Centre, Montreal, Quebec, Canada. rbissonn@globetrotter.qc.ca

UVA protection afforded by 6 different sunscreens with a sun protection factor of 21 or more was compared by means of the persistent pigmentation darkening method. Colorimetric and visual assessment showed significant differences in UV radiation-induced pigmentation at 2 hours. The labeled sun protection factor of the tested sunscreens was not predictive of UVA protection level.
