High-protection sunscreen formulation prevents UVB-induced sunburn cell formation.

A human sunburn cell (SBC) count is used to evaluate the reduction in UV-induced skin damage achieved by a highly protective sunscreen formulation containing 3 filters and reflective pigments (sun protection factor 34). Results indicate that, for the same minimal erythema level, SBC counts do not significantly differ between protected and unprotected skin, showing that the very high efficacy demonstrated against actinic erythema also extends to UV-induced skin damage.
