Description
In the Cosmetic and Personal care market almost every facial or body lotion is claimed to be a moisturizer. Even if its main claimed purpose is “anti-aging” or “cleansing” it is often also claimed to utilize a moisturizing activity. A moisturizer is a product designed to restore and maintain optimum hydration of the outermost layer of the skin, the stratum corneum. What is the “optimum level” of water in the skin? Where is water in the skin and how is it stored? What molecular structures bind it in the different skin layers? What are the physical and chemical mechanisms that allow enhancing moisturization and what can happen if we moisturize the skin too much?

In this 90 minute accredited online session we will review the current knowledge about the location and role of water in the skin, its evaporation rate and ways to maintain optimal amount of water to prevent dryness and preserve a healthy, strong barrier.
