Cosmetic Product for Improving Skin Moisturization and Barrier in Adults with Dry, Sensitive Skin

This clinical trial aims to find out if a specific cosmetic product can improve skin condition in adults who have dry, very dry, sensitive, and cracked skin that shows discomfort. The trial seeks to answer two main questions: whether the cosmetic product can increase skin hydration and skin barrier function, and if it can improve signs of skin discomfort. The potential outcomes of this study could help in managing dry and sensitive skin conditions more effectively. Participants in this trial will use the cosmetic product twice a day for a period of one month. They will also visit the research center on the first, second, seventh, and twenty-eighth day of product use for evaluations. The effectiveness of the product will be measured by changes in skin barrier function and skin moisturization from the start to the end of the trial. Skin barrier function is defined by the amount of water loss through the skin, with a lower value indicating improved skin barrier function. Skin hydration is defined by the skin's capacity to hold water, with a higher value indicating more hydrated skin.
