I overheard a woman on TV the other day explaining that you must buy silk pillows because cotton pillows will leave creases on your face that will turn into wrinkles. A makeup saleswoman told me once that I need to apply makeup with my ring finger because it's the weakest. Using a stronger finger may cause wrinkles.
Wrinkles are going to happen, ladies. Let's not get crazy and micromanage our skin. Skincare doesn't need to be complex.
Wash off your makeup.
If you're not doing those things, no pillowcase will help. In spite of all your efforts, you're still going to wrinkle because that means you've lived in your face. Living is not a failure. It is not something to hide. The best you can do is live well and aim for laugh lines.
