What are ceramides?
Ceramides are essential lipids naturally found in the skin that strengthen cell cohesion, thus reducing transepidermal water loss and re-establish the barrier function to protect the skin from environmental stressors. They make up over 50% of skin’s composition.
As the skin matures, there is a reduction of ceramides naturally present in the skin, resulting in a compromised barrier function that weakens the skin’s moisture-retaining properties.
Exposure to hot water, soaps, certain chemicals and other environmental factors may also reduce the effectiveness of your skin’s natural ceramides and can eventually deplete them. Therefore, dry, irritated and sensitive skin also often lack ceramides, making it more vulnerable to environmental elements, seasonal changes and airborne pollutants.
