Ceramides are a selection of lipids naturally found in the waterproof barrier that sits on top of the upper layers of the skin. As we age, our natural production of ceramides dwindles, resulting in dry skin, wrinkles and even dermatitis. Ceramides in skincare can help to replenish the skin’s natural protective barrier with ease, as they are ‘skin identical’ and are therefore well recepted by the skin. They are essential for retaining water, regulating cells and helping to repair the skin’s natural protective shield.
