Synopsis %26lt;br%26gt;Objective %26lt;br%26gt;To propose a new way of classifying sunscreens, which combines the labelled SPF with an objective measure of compliance. %26lt;br%26gt;Methods %26lt;br%26gt;The in vitro determination of uniformity of sunscreen application was combined with an in vivo measure of applied thickness to derive a Compliance Factor for each of 10 sunscreens. %26lt;br%26gt;Results %26lt;br%26gt;The predicted SPF resulting from real-life application of each sunscreen product, which is termed the SPFin vivo (veritas), was calculated from the Compliance Factor and the labelled SPF. It was shown that for a number of products, there is expected to be a significant mismatch between labelled and delivered SPF. %26lt;br%26gt;Conclusion %26lt;br%26gt;We believe that by adopting our proposal, consumers would be given more appropriate guidance on the delivered photoprotection they can expect to receive than relying solely on the labelled SPF.
