Retinoic acid has a protective action on the epithelium. Its derivatives are highly effective in treating and preventing ultraviolet-induced damage to the skin following exposure to ultraviolet radiation. Ultraviolet rays act through many mechanisms to damage exposed skin. One chief route is by inducing the AP-1 transcription factor, a protein which stimulates the expression of protein-degrading enzymes called matrix metalloproteinases […]
