These are another innovative ingredient for restoring youthful skin is a high concentration of ceramides, or lipids similar to those found in cell membranes and brain tissues. These oily lipids are essential in maintaining the protective functions of the skins outermost layer, known as the stratum corneum.
Ceramides play an important role in generating and sustaining the water permeability barrier in the skin.As such, they are important for improving skin hydration, reducing susceptibility to irritation, and restoring skin integrity.
Youthful skin is noticeably bright and glowing largely because it is well hydrated. Unfortunately, ceramide concentrations in the skin decline with age, leading to dry, rough skin.6 Topical application of ceramides has been shown to capture and bind water, which is required for the skin to remain supple, smooth, and hydrated.
