Ceramides are a class of lipids naturally present in the epidermis, playing a crucial role in cell cohesion to establish a robust barrier against moisture loss. This barrier is essential for shielding the skin, preventing dryness, and preserving tissue hydration so they are a crucial ingredient for maintaining the skin's barrier function. As a molecule identical to naturally present in human skin, Ceramide IIIB is exceptionally well-suited for providing prolonged long-term protection and support for the recovery of sensitive and dry skin promoting skin comfort.
