First, why not wash your face with cold water in summer?
Zhang Gengliang, chief physician of the Department of Endocrinology, Hospital of Traditional Chinese Medicine, Hebei Medical University, said: "Cold water perspiration, tangible water stagnation of the skin. Close the sweat. So the body is hot and painful." Said that because people sweat, subcutaneous vasodilation The pores are enlarged and the blood circulation is accelerated. If suddenly the cold water is poured into the body, the subcutaneous blood vessels will contract immediately, and the pores of the sweat will be closed immediately. The secretion of sweat glands will stop immediately, and the heat dissipation channel will be blocked. The body's heat cannot be stopped. Continue to distribute, making people feel hot skin, so it is not cool, but also susceptible to colds or other diseases.
Second, the danger of washing your face with cold water in summer
The oil on the face in the summer is more serious. If you wash your face blindly with cold water, the oil and cold water on your face will solidify after encountering it. When the face is full of sweat, greasy and dusty mixture, washing your face with cold water is equivalent to not washing, and may even cause acne.
1, large pores, small acne
Someone came home from the outside with sweat and sweat. The picture was cool and refreshing. When I opened the faucet, I washed my face with cold water.

In view of the fact that many women in the summer want to use sunscreen or cream, and will produce more oil in the day, it is best to use double face washing when washing your face - that is, remove makeup and then wash your face, whether you have makeup or not. Because the general makeup remover has good oil solubility, it can dissolve the dirt of the pores and prevent the formation of acne. After using the cleansing milk, you should use a foam-rich cleansing product and wash your skin with warm water.
