Résumé : |
The protection of the skin against UV-A induced free radical damage has become a major field of research in skin care. UV-A sunscreens and radical scavenging vitamins are presently the most widely used cosmetic ingredients for this purpose. The idea of enlisting natural defense mechanisms such as enzymes is hampered by their inherent instability in cosmetic formulations.
The present paper demonstrates that heat stable enzymes with protective properties can be characterized in thermophilic bacteria obtained from oceanic hydrothermal vents. Isolation and study of anti-oxydant properties of these enzymes are described. In vitro and in vivo experiments show that the extremozymes could be a useful alternative or supplement to vitamins in cosmetic formulations. |
