Absorbing less moisture than cotton, sleeping on silk keeps your skin stay more hydrated. This means your pricey serums actually get to work harder for you instead of being wiped off overnight by your pillow.
“Silk is a great option for those with sensitive skin,” says Dr. Elizabeth Tanzi, Founder & Director of Capital Laser & Skin Care and Associate Clinical Professor, Department of Dermatology at the George Washington University Medical Center.
In fact, as an alternative to cotton, silk is superior. In comparison, cotton actually dries out your skin and hair.
