Just washing your pillowcase often really reduces breakouts on your cheeks lol.

I used to get these bumpy flakes constantly popping up on only one side of my cheek, so I thought my cosmetics weren't agreeing with me. ㅠㅠ But it turned out it was because I have a habit of sleeping on my side and wasn't washing my pillowcase often enough. ㅋㅋ Once I started sleeping with a towel underneath once a week or changing the cover right away, the breakouts on my cheek disappeared like magic. ㅠㅠ If you happen to have particularly severe breakouts on only one side of your face, try changing your pillowcase first!
