How often should you wash satin pillowcases?

How often you should wash satin pillowcases depends on the fiber and your skin type, but the general guidance is similar to other pillowcases, with extra care for delicate fibers. For hygiene and skin health, dermatologists generally recommend washing pillowcases every 3 to 7 days, because pillowcases accumulate facial oils, sweat, bacteria, dead skin cells, hair products, and skincare residue that can contribute to acne and irritation. If you have acne-prone or very sensitive skin, washing twice a week is better. If you have dry skin and use heavy overnight creams, weekly washing may be sufficient. For polyester satin pillowcases, you can machine wash them weekly in cold water on a gentle cycle and tumble dry on low. For real silk satin pillowcases, which are more delicate and expensive, you should wash them every week as well, but using a much gentler method. Hand wash in cold water with a pH-neutral detergent designed for silk, avoid fabric softeners and bleach, do not wring, and hang to dry out of direct sunlight. Always have two pillowcases so you can rotate while one is being washed.
