There are two main factors that determine the process of ageing. One can be termed as intrinsic factor while the other can be termed as extrinsic factor. The entire age of a human being is divided into these two broad categories. Now, if we explore into the causes that influence extrinsic or external ageing, we would come across the fact that a good number of extrinsic factors accompany the normal ageing procedure. These factors affect the skin of the body and make it age premature.

Sun exposure serves as one of the most important constituents that have telling affect on the outer layer of the skin. The harsh ultraviolet rays from the sun contain everything that can damage the skin. Some of the other chief factors responsible for ageing the skin of the body prematurely are smoking, defective sleeping positions, gravity, repetitive facial expressions and improper food.

It is a proven fact that the ultraviolet sunrays damage the skin beyond imagination. Apart from the direct heat of the sun, the squinting habit to avoid the sunrays is also very harmful for the health of the skin. Study shows that women in southern hemisphere who are around the age of 20 years look as if they are double of their ages because of their squinting habits. This habit leaves crow's feet round their eyes which become horribly deeper.

These symptoms occur in them because of their continuous squinting for hours together. The same thing occurs when one smiles but the process of smile generally does not last more than 10 seconds, it does not leave the crow's feet impression around the eyes of happy people. No matter if you expose yourself just a few minutes only; you are under the threat to have noticeable changing to your skin.

These small changes include age spots, freckles, leathery and rough skin, spider-veins on the face, delicate wrinkles which disappear when they are stretched, blemished complexion, loose skin, actinic keratoses, and actinic keratoses. Sometimes, the exposure to sun also leads to skin cancer.

Dermatologists most often refer a term called ?Photoaging.? They use the term to describe a particular type of ageing for which is mainly caused by the exposure to sunrays. The quantity of photoaging which develops inside the skin depends on the skin color of a person and the history of long term exposure to sun.

Study in this respect suggests that fair-skinned people who have a long history of exposure to the sunrays are susceptible to catch the signs of photoaging easier than those with dark skin. The symptoms of photoaging in dark skins are generally confined to fine wrinkles only.
