Ceramides

Ceramides

Ceramides —naturally occurring lipids in the skin’s uppermost layer that form a protective barrier and reducing natural trans-epidermal water loss. Ceramides repair the stratum corneum layer in cases of dry skin, improve skin hydration, and increase the feeling of softness. They are beneficial for stressed, sensitive, scaly, rough, dry, aged, and sun-damaged skin. Ceramides play an essential role in the structure of superficial epidermal layers and form an integral part of the intercellular membrane network. Ceramide production decreases with age, accentuating any tendency to dry skin. When incorporated into a skincare preparation, the topical application of ceramides could benefit the stratum corneum if the ceramides manage to fill the intercellular spaces and if they are hydrolyzed by the correct extracellular enzymes on the skin. Topically applied ceramides have been shown to capture and bind water, necessary for the skin to remain supple, smooth, and hydrated. Natural ceramides are obtained from animals and plants. While ceramides can be synthetically manufactured, it is hard to obtain an identical equivalent to those found in nature, making them expensive raw materials.
