Here’s How Often You Should Change Out Your Pillowcase

Changing out your bed linens can be such a chore. From removing your sheets to the dreaded act of putting a duvet cover on the comforter, there’s a reason this task always seems to be on the to-do list. While it might not feel like a big deal to skip out on now and then, sleeping on the same pillowcase for too long can have consequences, especially when it comes to your skin. “Most people don’t realize how much oil, bacteria, and dead skin cells can accumulate on your pillowcase—all of which can contribute to acne breakouts and skin irritation,” says Dr. Sandra Lee, AKA Dr. Pimple Popper and Founder of SLMD Skincare.

So, how often should you change out your pillowcase? Here’s what the experts have to say.

Here’s How Often You Need To Change Out Your Pillowcase

Dr. Lee recommends changing out your pillowcase (along with your sheets and towels) at least once a week to maintain good skin health. “However, if you have oily or acne-prone skin, or if you sweat a lot during the night, you might benefit from changing it more frequently, maybe every two to three days.” 

Signs You Need To Change Your Pillowcase

Even if you plan for a weekly or bi-weekly laundry session, your linens may need to be changed out more frequently. Here’s what to keep an eye out for. “If you notice odor or any visible signs of discoloration/stains that require cleaning before that seven-day deadline rolls around, that’s a good sign it’s time for a swap,” says Mariana Salazar, licensed esthetician and aesthetic specialist, Revive Med Spa.

If you find you’re constantly waking up with a greasy pillowcase, you also may want to re-evaluate your skincare, according to Jennifer Yen, skincare expert and founder of Pūrlisse. She suggests switching your moisturizer to something more lightweight such as Blue Lotus Balancing Moisturizer. 

You may also want to keep in mind those greasy splotches could be from hair products. “Something many don’t realize is that leave-on styling products we apply on our hair can then easily be transferred onto our skin via our pillowcase. For those with sensitive skin, this can cause further irritation or congestion that can be avoided with routine pillowcase changes,” Salazar explains.

Lastly, if you are recovering from a cold, flu, or similar condition—don’t be afraid to freshen up your pillowcase a few days early. 

How To Wash Your Pillowcase

Whether your pillowcase is silk, bamboo, cotton, or some other material, it’s important to make sure you wash it properly. “Always follow the manufacturer’s instructions. But in general, turn your pillowcase inside out and use a mild detergent free of dyes, perfumes, and fragrances. If you have a silk or bamboo pillowcase, use a mesh bag to keep it protected from tearing. Always use warm water to effectively kill bacteria and avoid fabric softeners that can leave residues,” says Salazar. “We love using the gentle cycle and letting our pillowcases air-dry to preserve the fine threads. And lastly, don’t forget to routinely wash your pillows as well!”
