I have been mostly using cotton pillowcases so far. Over time they tend to have lint like fluff perhaps because of the material or my hair and face. Either ways, they look old pretty soon. My skin is very oily and the cotton pillowcases seem to absorb them leaving spotted stains. While browsing other products I came across this pillowcase and I love sky-blue. The product information seemed to indicate that it is good for skin which is not my main concern but was good to know and that silk pillowcases feel better. I definitely agree with the latter. Compared even the highest thread count cotton pillowcases I've tried, this silk pillowcase seem to feed really good and smooth. I never even thought about silk pillowcases and now I think I will never go back to cotton ones. This is a really good product you should give it a try if you haven't done so. I give a big thumbs up for this one.
