Sleeping with a towel placed on the pillowcase that touches your face every day is highly effective for preventing milia around the chin.

Are there any of you who use gentle skincare products and cleanse thoroughly, yet strangely experience recurring breakouts only on the cheek or jawline on the side where you sleep lying on your side? For a while, I also had tiny bumps on only one cheek and didn't know why. I heard that sweat, saliva, and oil from hair accumulate on the pillowcase overnight, creating the perfect environment for bacteria to breed. Since washing the pillowcase every day is a hassle, I established a routine of placing a clean cotton towel on my pillow before bed and replacing it with a fresh one daily. Surprisingly, after adopting this habit, the unexplained tiny bumps on my cheeks and jaw completely disappeared. Everyone, please check your pillow hygiene.
