C22 Ceramide is widely used in skincare and cosmetic formulations due to its role in maintaining the skin’s barrier function. It helps retain moisture, making it effective in treating dry, sensitive, or aging skin. Found naturally in the stratum corneum, synthetic or bio-identical C22 Ceramide is added to moisturizers, serums, and anti-aging products to reinforce the lipid matrix, reduce transepidermal water loss, and improve skin resilience. It is particularly beneficial in products designed for conditions like eczema, psoriasis, and dermatitis, where the skin barrier is compromised. Its compatibility with other lipids allows it to be combined with cholesterol and fatty acids to mimic the natural lipid bilayer, enhancing repair and protection of the skin.
