Silk, like that used in our signature TriSilk or Clean Silk fabric found in our NIGHT products, is a natural fiber whereas our satin is made of manmade materials. Silk offers a few extra benefits over satin, like being hypo-allergenic and full of amino acids. But, our satin is still really, really good for your skin and hair.
