Wrinkles are one of the most unpleasant and unbearable skin problems for humanity. It betrays human age and brings misfortune to many people. Skin wrinkles causes are numerous. Some of them have natural origin, others are human controlled. Genetic predisposition plays a significant influence in this case but the sun exposure seems to be the strongest among the skin wrinkles causes.

The result of the sun exposure and UV-radiation is premature skin aging called photoaging. The worst variant of sun exposure influence is skin cancer, even by the age of 20.

Weak immunity against infections, skin cancers, aging skin disorders, deep wrinkles are caused both by UVA and UVB rays. Collagen fibers that are responsible for skin structure and elasticity lose their abilities instead of normal processes the metalloproteinases production starts development.

Abnormal amount of these enzymes degrade the collagen that is resulted in solar scars and skin rebuilding; the recurrence of these processes cause the emergence of strong wrinkles. Unfortunately the line of environmental factors (as skin wrinkles causes) is not limited by sun exposure. Pollution, smoke, ozone influences are obviously not salutary! Oxygen free radical produced under the impact of these factors damage cell membrane and starts interacting. The researchers guess that is one of the skin wrinkles causes.

Skin sagging and as result wrinkles development has direct connection with weight loss and reducing of the fat cells volume. Some of the most vexing skin wrinkles causes are facial habitual expressions, smoking and even sleeping position. They are referred to this group as they can be but are not controlled by human him/herself. The result of air pollution is considered to be the reduction of vitamin E in the skin. The thinner skin cells gift the thinner skin look and skin functions disorders.

The skin of inveterate smokers is prone to quick thinning. That explains the fact of smokers' older appearance comparing with non-smokers. The difference between the face conditions of these two groups of people is usually obvious. It is proved that while smoking the agents responsible for skin aging are activated that starts collagen breaking down. The smokers lose skin elasticity as the collagen is exactly the natural protein that is responsible for skin structure and elasticity.

Let us look at this problem from inside! What is the picture of wrinkle mechanism here? The fact is that during the years the skin loses its ability to quick cell dividing. Its slower renovating (cell dividing) causes dermis layer thinning.

At the same time the atrophy of the fat cells under the dermis is constantly going on; elastin and collagen lose their abilities (that creates frowning and sagging effects). The skin gets dry and scaly because of glands atrophy as a result retain moisture abilities diminish. Facial lines and crow's feet development is almost inevitable. Probably the forehead wrinkles influence drooping eyes. The problem of skin healing problems is more and more actual with the age.

Normal aging skin changes added by gravity, facial expressions, sleeping position and of course sun exposure and smoking represent the set of skin wrinkle causes.
