What Causes Wrinkles?

It is widely known among medical researchers that people with wrinkles may have a genetic connection in developing severe wrinkling. However, one of the most primary causes of wrinkles is sun exposure; the sun is mainly responsible in promoting and worsening skin wrinkling. Smoking may also negatively impact the skin. Due to this, wounds become difficult to heal. Lines that appear between the eyebrows, known as frown lines and crow's feet which are thin lines that develop from the eye corners, form due to relentless small muscle compressions. Certain habits cause expressions on the faces and these, over a period of time, form in to characteristic lines, thus adding to the development of facial jowls or drooping eyelids, as observed in some people. Old age also causes the skin to lose its elasticity. When the skin gets pressed upon, it does not spring back to its original position like it used to, but rather sags and develops furrow-like lines. As the oil-secreting glands beneath the skin begin to atrophy, the skin starts to get deprived of its protective water-lipid coatings. The skin's power to hold back moisture gets reduced the skin gets dry and scaly.

Causes of Wrinkles on Face


In most people the skin tends to age prematurely due to prolonged exposure to the harmful effects of the ultraviolet (UV) radiation emanating from the sun. The wrinkling that happens due to the sun is also known as extrinsic or photoageing. The exposure to ultraviolet, also cited as UVA or UVB, radiation from the light of the sun answers for almost 90 percent of the indications of premature skin ageing, and most of these effects take place by the age of 20. Both UVA and UVB rays are known to bring about damage leading to wrinkles. Apart from just wrinkling, these radiation effects lead to lowered immunity against infection, skin disorders related to ageing, and malignancies of the skin.

Even little amounts of UV radiation can impair collagen fibers that are the important structural protein of the skin, and cause a collection of unnatural elastin, which is the protein that makes the tissue to stretch. During the procedure, prominent quantities of enzymes known as metalloproteinases are developed. The standard function of these enzymes is to reconstruct the sun-injured tissue by synthesizing and regenerating collagen. Since this turns out to be an imperfect procedure, as some of these enzymes actually begin to degrade the collagen. The result that takes place is a mismatched development or matrix of disorganized collagen fibers identified as solar scars. If this procedure of imperfect skin reconstructing takes place over and over, wrinkles can form.
