Routine washing of the skin with soap has been shown to remove the NMF from the superficial layers of the stratum corneum. In fact, the outermost layers typically show reduced NMF levels, largely due to bathing or exposure to UV light. In addition, aging appears to dramatically reduce the amino acid content in the stratum corneum. Studies have shown a significant correlation between the hydration of the skin and its amino acid content. All of these conditions show characteristics of abnormal desquamation, with the accumulation of corneocytes resulting in the visible dryness, roughness, scaling, and flaking properties of dry skin
