Causes of skin aging.

Why Does Skin Age:


Natural aging process:
The skin aging does not occur overnight but over the years.The aging process begins during the mid-20s.While the function of the whole body decreases with age,the skin's functiom and activity also slow down.The epidermis becomes thinner and pale due to the slow renewed skin cells and the decrease of melanocytes.The demis containing collagen,elastin,blood vessels and nerves also starts to lose its elasticity and become fragile bruised.The less production of oil and sweat by the glands make the skin dry and itching.That situation happens to everybody and you can never stop that.The only way is to delay the process of skin aging.

Sunlight:
Each person exposes skin to sunlight for many years and without any protection,the skin would be seriously damaged by the ultraviolet rays.

Facial Expressions:
Rich facial expressions lead to fine lines and wrinkles as well.Especially when the skin ages and loses its elasticity,the skin can't completely springing back to its line-free state,and these grooves gradually become the fine lines and wrinkles.

Nutrients:
Poor diets of lack of Vitamin A,Vitamin C,Vitamin E,Vitamin D,essential fats, and zinc results in various skin problems  including skin aging.
