What are ceramides and why are they important?

Ceramides are lipid molecules that make up approximately 50% of the skin's barrier structure, holding skin cells together like mortar between bricks. They prevent moisture loss and protect against environmental irritants and pathogens. As we age, ceramide levels naturally decline, weakening the barrier. Topical ceramide products help replenish these lipids, making them essential for dry, eczema-prone, or barrier-damaged skin.
