Zusammenfassung
Im beruflichen Hautschutz werden traditionell die Anwendung eines Schutzpräparates vor der Arbeit, die schonende Hautreinigung und die Verwendung eines Pflegepräparates nach der Arbeit gefordert. Die Wirksamkeit dieses integrierten Hautschutzkonzeptes wurde bisher jedoch nicht wissenschaftlich überprüft. In der vorliegenden Studie wurde die Wirksamkeit eines Hautschutzpräparates (Excipial Protect®), eines Reinigungspräparates (Excipial Clean®) und eines Pflegepräparates (Excipial Repair®) auf die kumulative Irritation durch Natriumlaurylsulfat (SLS) an hautgesunden Probanden einzeln und in Kombination überprüft. Die Irritation wurde klinisch und mittels nichtinvasiver hautphysiologischer Messverfahren (transepidermaler Wasserverlust, Hautfeuchtigkeit und Hautrötung) erfasst. Unsere Ergebnisse zeigen eine statistisch signifikante Verringerung der SLS-Irritation durch Anwendung der Schutzcreme und des Hautreinigungsmittels sowie durch Anwendung von Schutzcreme, Hautreinigungsmittel und Pflegecreme. Durch Anwendung von Hautreinigungsmittel und Pflegecreme konnte hingegen keine signifikante Verminderung der SLS-Irritation erreicht werden. Die Verbesserung der Hautfeuchtigkeit durch Kombination von Schutzcreme, Hautreinigungsmittel und Pflegecreme war besser als bei Einzelmaßnahmen. Zusammenfassend konnten wir erstmals die Wirksamkeit eines integrierten Hautschutzkonzeptes in der Prävention des kumulativ-subtoxischen Kontaktekzems zeigen. Dabei ist die Anwendung einer präexpositionellen Schutzcreme das bedeutsamste Glied in der Kette der Protektivmaßnahmen. Die zusätzliche Applikation eines hydratisierenden Hautreinigungsmittels und einer regenerierenden Hautpflegecreme ohne okkludierende Eigenschaften verstärken den positiven Effekt auf die epidermale Barriere durch Verbesserung der Hornschichthydratation.
Abstract
Occupational skin care is composed of application of a protective cream before work, mild skin cleaning and application of a skin care product (moisturizer) after work. However, the efficacy of an integrated skin care program as described has not been scientifically evaluated. In the present study, the efficacy of a protective cream (Excipial Protect®), of a skin cleaning product (Excipial Clean®) and a skin care cream (Excipial Repair®) on the cumulative irritation by sodium lauryl sulfate (SLS) was assessed in healthy volunteers. The products were tested alone and in combination. The irritation was assessed clinically and by non-invasive methods (transepidermal water loss, capacitance, and erythema). Our results show a statistically significant reduction of SLS irritation by combined application of the protective cream and the skin cleanser, and by combined application of the protective cream, the skin cleanser, and the skin care cream. The combined application of the skin cleanser and the skin care cream, however, did not reduce SLS irritation. The improvement of the skin capacitance as indicator of stratum corneum moisture by the combination of the protective cream, the skin cleanser, and the skin care cream was more effective than by the single products. In conclusion, we could show the efficacy of an integrated skin care concept in the prevention of cumulative irritant dermatitis for the first time. The application of the protective cream seems to be the most important step. The additional application of a rehydrating cleanser and of a regenerating skin care cream enhance the positive effect on the epidermal barrier by improvement of stratum corneum hydratation.
