Contrary to what you may have heard or thought, there are not huge differences whether you decide to invest in whole Silk Pajamas or Faux Silk (Silk Satin) pajamas. In terms of their benefits for sleep and overall comfort, as well as your skin and hair, you should feel comfortable enough in opting for the more affordable AND cruelty-free option of Silk Satin Pajamas, as long as you are getting yourself a high-quality pair.
"Both satin and silk support healthy skin and hair while you sleep. Either of these materials is going to boost your beauty game more than more traditional bedding materials (ahem, cotton). Why? Because while other materials may tug at your hair follicles and strip your skin of natural, important oils, satin and silk provide a smooth sleep surface. Skin and hair gently glide across as you catch z’s, reducing friction and leaving your skin and hair hydrated. This is key in helping to reduce bedhead, hair breakage, fine lines and wrinkles and dull, dry skin.Now for the key difference. Silk is a natural material produced by the silk worm. Satin was originally produced as a weave using silk fibers to enhance the look and feel of the material (think: extra shiny and smooth). Slowly over time, this same effect could be achieved incorporating sophisticated manmade fibers, leading to today's ability to produce satin as a solely synthetic fiber."
