Zusammenfassung

Der Nutzen von Sonnenschutzmitteln mit Lichtschutzfaktoren (LSF) jenseits 50 ist umstritten. Um eine Irreführung des Konsumenten zu vermeiden, sind mehrere Länder bereits dazu übergegangen, LSF über 50 nicht mehr auf Sonnenschutzmitteln zu deklarieren. Argumente gegen hohe LSF sind das Risiko eines unausgewogenen Schutzes, der die Gefahr von Schäden durch längerwellige ultraviolette Strahlung erhöhen könnte; Vermittlung eines falschen Sicherheitsgefühls, das zur zeitlichen Ausdehnung der Sonnenexposition verleiten könnte; gesundheitliche Risiken durch höhere Konzentration an Filtersubstanzen und die nur marginal höhere Lichtblockade. Demgegenüber steht die Erkenntnis, dass der funktionelle LSF von Sonnenschutzmitteln in der praktischen Anwendung ohnehin weit hinter dem deklarierten LSF zurückbleibt und daher der Einsatz von höheren LSF bei sensitiven Individuen und starker UV-Belastung durchaus Sinn machen könnte.

Abstract

The use of sunscreens with sun protection factors beyond 50 is controversial. In order to avoid misleading the consumer, several countries have already decided not to declare SPF beyond 50 on sunscreen products. Arguments against high SPF include the following: the risk of imbalanced protection, which could increase the risk of damage caused by longer-wave ultraviolet radiation; imparting a false sense of safety, which could lead to the extension of sun exposure times; health risks from higher concentrations of filter substances; and the only marginally higher blockade provided by high SPF sunscreens. On the other hand, it has been realized that the functional SPF of sunscreens remains far behind the declared SPF in the practical application and, therefore, the use of higher SPF in sensitive individuals and during strong UV exposure could make sense.
