The present invention provides compositions containing a mixture of cholesterol sulfate and an exfoliant. The exfo-liant can be N-acetyl-D-glucosamine, N-acetylgalactosamine, or a combination thereof. The combination of the cholesterol sulfate with the exfoliant surprisingly enhances the skin barrier even though the activity of each of the components is opposite the other. In addition, because of the ability to enhance or repair the skin barrier function, methods of improving or maintaining a healthy skin barrier are included in the present invention by applying to the skin an effective amount of the mixture of cholesterol sulfate with the exfoliant. The mixture can also be useful in treating or preventing damage to the skin, where the damage is caused by a compromised skin barrier function. As a result of improving the skin barrier function with the combination of cholesterol sulfate and the exfoliant, the appearance of lines and wrinkles is generally reduced; rough and dry skin conditions are also improved.

L'invention concerne des compositions contenant un mélange de sulfate de cholesterol et d'un exfoliant. Ledit exfoliant peut être un N-acetyl-D-glucosamine,un N-acetylgalactosamine, ou une combinaison de ceux-ci. La combinaison de sulfate de cholestérol et d'exfoliant améliore de manière surprenante la fonction barrière de la peau même lorsque l'activité de chaque composant est opposée à celle de l'autre. Du fait de l'aptitude à améliorer ou réparer la fonction barrière de la peau, l'invention concerne également des méthodes permettant d'améliorer ou de conserver une barrière de peau saine par application d'une quantité efficace de mélange de sulfate de cholestérol et d'exfoliant sur la peau. Ce mélange peut également être utile pour traiter ou prévenir un dommage cutané, ce dommage pouvant être provoqué par une fonction barrière de la peau compromise. Du fait de l'amélioration de la fonction barrière de la peau à l'aide de la combinaison de sulfate de cholestérol et d'exfoliant, l'apparition de lignes ou de rides est généralement réduite. L'invention concerne enfin l'amélioration d'états de peau sèche et rugueuse.
