Synopsis A novel in vitro technique for measuring the efficacy of sunscreens over the skin surface is described. It is demonstrated that those products that spread easily are associated with both a low variance in delivered SPF and a subjective assessment of a product that is pleasing to use, which in turn results in a higher application thicknesses and greater delivered photoprotection leading to improved health benefits of sunscreen use.
