It is also said that silk has beauty benefits. The naturally occurring proteins and oils in silk help care for your skin. Silk tends to draw less moisture away from your skin, while the smoothness of the fabric means that there is very little friction to pull at the skin and hair while you sleep. Which should lead to a smoother complexion and less tangled hair!
