Reciprocity for solar simulators used in sunscreen testing
1Clinical and Toxicology, Shering-Plough, Memphis, Tennessee 38151.
Abstract:
Reciprocity for sunscreen solar protection factors (SPFs) and for delayed erythema was examined using a solar simulator equipped with neutral density filters to vary the beam intensity. Similar SPFs were obtained over a 15-fold intensity difference, using a sunscreen with a low (SPF-4) and a high (SPF-15) protection factor. Reciprocity was also observed for delayed erythema in unprotected skin.
