Zusammenfassung
Die menschliche Haut ist von einer Vielzahl von Mikroorganismen besiedelt, der sog. Hautmikroflora. Diese bildet ein komplexes Netzwerk von Interaktionen der Keime untereinander und mit den Zellen der Haut. Moderne molekularbiologische Analysemethoden haben neue Einblicke in die komplexe Vielfalt der nur teilweise kultivierbaren mikrobiellen Organismen eröffnet. Die Mehrzahl der residenten Keime auf gesunder Haut mit einer ausbalancierten Mikroflora ist unschädlich, in der Regel vermitteln sie sogar eine Schutzfunktion. Insbesondere im Fall milder Formen mikrobieller Ungleichgewichte wie unreiner Haut/milder Akne oder trockener Haut/milder atopischer Dermatitis stellen prä- und probiotische Konzepte eine wirksame Alternative zu strikt antibakteriellen Produkten dar. Präbiotische Wirkstoffe bringen die Hautmikroflora wieder in ihr natürliches Gleichgewicht. Probiotische Applikationen bestehen bevorzugt aus inaktivierten Präparationen schutzvermittelnder Bakterien. Eine Reihe erfolgreicher In-vivo-Studien illustriert dieses aus dem Lebensmittelsektor abgeleitete, neuartige Prinzip einer schonenden Kosmetik, für das bereits erste kommerzielle Produkte im Markt erhältlich sind.
Abstract
The human skin provides a habitat for a variety of microorganisms, the skin microflora. There is a complex network of interactions between the microbes and cells of the epidermis. Modern analytical methods in molecular biology have revealed new insights into this complex diversity of partially unculturable microbial organisms. Most of the resident microbes on healthy skin can be regarded as being harmless or even beneficial to skin. In the case of diseases with some imbalance in microorganisms, such as impure skin/mild acne or dry skin/mild atopic dermatitis, pre- and probiotic concepts represent an effective alternative to strictly antibacterial products. Prebiotic actives rebalance the skin microflora while probiotic approaches predominantly consist of applying an inactivated microbial biomass of beneficial bacteria. Several examples of successful in vivo studies illustrate this new principle for gentle cosmetics derived from the food sector.
