(1) Change Your Pillowcase Frequently
We all know how important it is to keep our face clean, but how about our pillows? The typical American only washes their sheets once every week or two, but every night your face is rubbing against that pillow case. Imagine all the oil and bacteria that builds up on that pillowcase during that time! This is why it may not be a bad idea to try changing your pillowcase every night and see if that helps.
1.定期更換你的枕套
我們都知道保持臉部的干凈又多重要，但是我們的枕頭呢？ 典型的，一個(gè)美國人每一周或兩周清洗他的枕套，但是你的臉每晚都與枕套摩擦。想象一下那時(shí)在枕套上駐扎的油脂與細(xì)菌。所以，每晚更換你的枕套或許不是個(gè)壞建議。
