Ceramides Ceramides
Ceramides are lipids of the stratum corneum that, together with cholesterol and fatty acids, form the intercellular cement of the skin barrier. They make up about 50% of epidermal lipids, and their amount falls with age. In cosmetics they replenish the barrier, limit water loss and reduce skin sensitivity, including after acids, retinoids and treatments.
Protective Barrier0.5% ceramides (NP+AP+EOP complex): 42% reduction in TEWL, 46% increase in hydration over 21 days (Coderch et al., 2003, n=22).
Structurally identical to the native ceramides of the stratum corneum. They incorporate into the intercellular cement with cholesterol and fatty acids in a 1:1:1 ratio — the physiological proportion.
