New Research Shows How Phytoceramides Really Work on Skin

Phytoceramides, when used in lotions or taken orally as supplements, are said to enhance the skin's ability to retain moisture and to build more elastic layers. These are just like ceramides, a type of lipid, only that they are extracted from plants.
