The formulation of skin-identical ceramides with MultiVesicular Emulsion Technology (MVE) was the birth of CeraVe. We have the only line of skincare products with a unique blend of three essential ceramides, plus patented MVE technology that gradually releases our ceramide-enriched formula over an extended period of time. MVE is like a sphere with a series of layers that slowly dissolves, releasing the ingredients into your skin. The product continues to work after it is applied, hydrating your skin all day in just one use.
