I switched to a silk pillowcase and fixed both my facial marks and my hair.
I have a habit of never sleeping on my back and always on my side, so every morning I would have deep pillow creases all over my cheeks and around my eyes. They used to disappear quickly in my 20s, but as I got older, those marks wouldn't go away until lunchtime, which was truly shocking. So, I made the big decision to replace all my cotton pillow covers with soft, silky ones. It was slippery at first, so I couldn't get used to it, but starting the very next day, not a single crease appeared on my face! Plus, the friction my hair gets against the pillow while I sleep has decreased, so the frizziness at the back of my head when I wake up has improved dramatically. It feels like home care is taking care of me automatically the whole time I sleep.
