The effectiveness of a sunscreen containing methoxy cynnamate and dibenzoylmethane has been evaluated in 12 healthy volunteers. For each subject, two symmetric areas of bottoms (one of them previously receiving the sunscreen) have been irradiated with a bank of three 400 W metal halide lamps, emitting in the UVB range (max at 300 nm), in order to detect the Minimal Erythema Dose (MED). The MED values have been determined by a color analyzer. The results have shown that, at least in the UVB range, the MED values of the sunscreen-protected skin areas were 3-8 fold higher than that of the unprotected areas.

Abstract

The effectiveness of a sunscreen containing methoxy cynnamate and dibenzoylmethane has been evaluated in 12 healthy volunteers. For each subject, two symmetric areas of bottoms (one of them previously receiving the sunscreen) have been irradiated with a bank of three 400 W metal halide lamps, emitting in the UVB range (max at 300 nm), in order to detect the Minimal Erythema Dose (MED). The MED values have been determined by a color analyzer. The results have shown that, at least in the UVB range, the MED values of the sunscreen-protected skin areas were 3-8 fold higher than that of the unprotected areas.
