Comparison of UVA protection afforded by high sun protection factor sunscreens

J Am Acad Dermatol. 2000 Dec;43(6):1036-8. doi: 10.1067/mjd.2000.109299.


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.
