A small change can make a huge difference.
Congestion of the skin, resulting in blackheads, whiteheads, and other types of acne, can often be caused by a dirty pillowcase. Often in the treatment room I will notice that one side of the face has more clogged pores and breakouts than the other side. Invariably the side that the client sleeps on more often is the side with more problems.
The answer to, "How often do you wash your pillowcase?" in this situation ranges from "Maybe once a week or every other week" to "Uhhh... pretty much never?" which makes me cringe.
Fabric collects dirt, oil, makeup residue, dead skin cells, and bacteria, which we then lay our faces on for (hopefully) eight hours a night. Over time bacteria will thrive and multiply.
Ideally, a new pillowcase should be used every other night, flipping the pillow over the second night so you always have a fresh side to sleep on. This can be a bit overwhelming at first, so at the very least use a new pillowcase twice a week. Buying several extra pillowcases and washing them all at once can make it much easier.
