The symptoms of xerosis (dry skin) can be ameliorated by increasing the hydration state of the stratum corneum through a humectant or occlusive effect, smoothing the rough surface with an emollient, replenishing natural moisturizing factors, and normalizing the stratum corneum. We present the primary and secondary functions of various "active" and vehicle ingredients and include precautions regarding certain classes of materials. Recommendations on selecting moisturizing systems are made based on ingredient functionality and the severity of the dry skin condition. |
