It might seem like a minor thing, but I think bedding cleanliness is also important.
Lately, I've been getting acne only around my chin, so I wondered why and looked around for the cause.
I was wondering if it was a problem with my face wash or my cosmetics, but that wasn't the whole story.
The most suspicious parts were the blanket and pillow.
There may be many people here who take good care of their bedding cleanliness, but I wasn't one of them.
After I thoroughly tidied up my bedding, especially the duvet, my acne completely disappeared and hasn't come back.
At least the acne that kept appearing only around my chin has completely disappeared.
I used to sleep with the blanket pulled up to my chin.
I changed all my bedding because it was hot, but I'll make sure to wash it properly from now on. I'm also planning to use the laundromat again.
