Understanding Moisturizer Ingredients

Emollients are ingredients that remain in the stratum corneum to act as lubricants. They help maintain the soft, smooth, and pliable appearance of the skin. Emollients are often thought of as "filling in the crevices" between corneocytes that are in the process of desquamation (shedding). The type of emollient used in a moisturizer plays a key role in its "skin slip," which is the smooth feeling imparted to the skin after application.
