Many people think that the formation of blains can be hindered if the skin oil is controlled and the foods causing excessive internal heat are avoided. In fact, the main reason of causing blains is that the excessive secretion of facial oil blocks the pores. When the dirty substances are accumulated in the pores, blains can be caused. Many bad habits in everyday life can bring the dirty substances to the pores and cause blains. 

The first bad habit is touching face with hands. Many people like to touch face when they feel bored. Such a kind of action is a serious killer of the facial skin. Our hands always contact with the external objects and the dust and bacteria can be accumulated on them. When we touch face, the bacteria can be brought to face and cause blains. If people have to touch face, it is better for them to clean the hands in advance.

The second bad habit is washing face excessively. Washing face excessively can stimulate the secretion of the facial oil, which can accelerate the appearance of bacteria. Therefore, blains can be easily caused. It is suitable for people to wash face two times a day, namely, one time in the morning and one time in the evening. Of course, when people wash face, they must be careful enough to remove all the dust and bacteria. When the air is very dry, the times of washing face should be reduced. One time a day is completely enough.

The third bad habit is inadequate intake of water. In order to protect the skin, it is necessary to maintain the balance of water and oil inside the skin. The inadequate water can cause the excessive secretion of oil. People should drink nearly 8 cups of water every day to maintain a kind of balanced relationship between oil and water.

The fourth bad habit is too late sleeping. The period between 10 p.m. to 6 a.m. is the best time for people to fall asleep, as the period between 10 p.m. to 2 a.m. is the most active time for the skin to conduct metabolism and is also the best time for the skin to repair and protect itself. Therefore, it is essential for people to grasp the period.

The fifth bad habit is inadequate intake of vegetables. Many people do not like to eat vegetables. In fact, the cellulose contained in vegetables can improve the digestion for the digestive tract and maintain the smoothness of the intestinal tract. In addition, vegetables contain various kinds of vitamins, which can further protect the skin and prevent the formation of blains.
