The Hydration Series: Part Four: Mature Skin Is Especially Prone To Dehydration
With age, a natural slowing of skin function occurs. Over time, less and less sebum is produced by the sebaceous oil glands and overall hydration levels drop. The skin’s natural moisture factor diminishes and less epidermal lipids (oil-like substances) such as ceramides, cholesterol, and glycosaminoglycans that are produced within the skin. The result is skin that is less smooth and supple and has less lubrication. Lubrication is what is needed to prevent mechanical stress and without it the skin is more prone to cracking, flaking, wrinkling and incurring other signs of aging.
