You may think women will not suffer from aging until they reach 40 years old. In fact, when women reach 25 years old, the function of the cells in their body begins to decline gradually. Anti-aging can be said as a lifelong career for women. As a result, every woman should clearly know the following five bad habits which will accelerate skin aging.

First, always staying up all night
Staying up late is the biggest enemy of the young skin. Lack of sleep will disturb various regulating activities of skin cells and affect the microcirculation of the skin. In such a case, the metabolism of skin tissue will be in disorder, and the absorption of nutrients by the skin will be hampered, which will accelerate skin aging. What's more, lack of sleep will directly affect the endocrine system, which also has great impact on the condition of the skin.

Second, smoking or drinking alcohol
has a contracting effect on the blood vessel of the skin, so the smokers are more likely to suffer from wrinkles than non-smokers. As a result, if you are a smoker, maybe you will look 10 years older than your contemporaries. While drinking alcohol will reduce the amount of lipid contained in the skin, which will make the skin dehydrated and indirectly affect the normal function of the skin.

Third, too much solar exposure
A large number of long-wave and short wave ultraviolet light will directly damage the elastic fibers and collagens in the depth of the skin. This will lead to the physical changes and structural changes of the skin, and make the facial skin lack of luster. What's more, it can also result in the formation of wrinkles and spots on the skin.

Fourth, do not drink enough water
The water content in the stratum corneum of the skin is between 15% to 25%. If the water intake is not enough, it will not only lead to the lack of water in the cells of the skin, which will affect the synthesis of elastin and collagens, but also can affect the water content in the stratum corneum of the skin. As a result, it will speed up the aging of the skin.

Fifth, lack of exercises
The right amount of exercises can promote blood circulation in the whole body, increase human immunity, and make people away from the intrusion of the pathogenic bacteria. What's more, it can also make the skin sweat a lot, so as to promote the excretion of waste from the body. In addition, it can regulate the PH value of the skin, and significantly delay skin aging.
