Wash Your Pillowcase on the Regular
Acne is worsened by popping pimples. Acne Mechanica is a form of acne caused by objects or materials touching your face. When you don't wash or change your pillowcase on a regular basis, dirt and oil from the environment, as well as your skin and hair touching the pillow, are transferred back onto your skin. This can create acne by clogging pores.
The truth is that your pillowcase should be washed at least once a week. Of course, this isn't a hard-and-fast rule, but it's regular enough to avoid accumulating dangerous amounts of contamination, and it's also doable for most individuals. If you have oily skin, you may want to do it more often and make sure your pillowcase is clean and oil-free. Besides, you should be cleaning everything that touches your face weekly, including your makeup brushes, beauty blenders, and phone.
