For many people, they can be “better” mainly because they feel more comfortable. Silk is smooth and can reduce friction, which may help with irritation or noticeable sleep creases, especially with a silk pillowcase. Some also prefer that silk feels less rough than standard cotton.

However, “better for your skin” is not a universal truth and it is not a medical guarantee. Acne, for example, depends on many factors such as hormones, skincare routine, bacteria balance, and products. A clean pillowcase often matters more than the fabric alone.

If you choose silk, wash it regularly and use a mild detergent, because product residue can irritate the skin. Think of silk as a skin friendly comfort upgrade, particularly if you are sensitive to friction.
