What is Wrinkle?

Wrinkles, fine lines and deep furrow are formed when our epidermis is unable to maintain the adequate amount of water to keep our skin moisturized. Once our skin do not contain sufficient collagen, it will become sagging thus forming wrinkles. There are two main factors that causing the wrinkles, intrinsic factor due to normal aging and extrinsic factor which is caused by repeated exposure of sun ultraviolet (UV) radiation and tobacco smoking. Naturally aged skin appeared to be smooth, dry, pale and finely wrinkled whereas photoaged skin usually is more coarsely wrinkled. Repeated or long period of exposure to UV radiation causing excessive matrix metalloproteinase (MMP) leading to degradation of collagen, collagen deficiency in skin thus forming wrinkles. Besides, it was found that Crow's feet, a branching wrinkle at the outer corner of a person's eyes are more noticeable in smoker than non-smoker. Some wrinkles are also caused by certain habits such as frowning, squinting and grimacing.

How It Affects Your Body

There are two main factors that cause wrinkles, which are the intrinsic factor - chronological ageing - and the extrinsic factor - repeated exposure to solar ultraviolet (UV) radiation and tobacco smoking.

The ultraviolet of the sun can cause premature ageing (photo-ageing) to the skin, damaging the skin tissues and collagen fibres in the skin. Hence, making it less efficient in collagen formation. Besides that, researchers have also found that smoking causes a marked reduction in the production of collagen, thus more likely to develop wrinkles.
