Causes of wrinkles

Causes of wrinkles

.Unfortunately, there are some factors that determine if we’ll have wrinkles that are out of our control. There are genetic factors, as some families simply wrinkle more than others, while those with fair skin and blue eyes are more likely to suffer from sun damage which can promote wrinkles. This doesn’t mean, however, that those with darker complexions are less likely to have wrinkles, however.

Over-exposure to UV Rays cause skin to get dry and even crackly. Small wrinkles on your skin are the result of these little cracks. Avoid sun-tanning, and apply sunblock when you go out.Whether because of work or a love of outdoor activities such as cricket, sailing, or sun bathing, are equally susceptible to sun damage. Unfortunately, there is no such thing as "safe tanning", so sun worshipers are likely to run the risk of developing wrinkles wherever they expose their skin to the sun. Smoking can also damage the skin and lead to wrinkles.
Skin becomes saggy when you lose too much weight at one go. Wrinkles are a result of lines formed when your skin folds over. Maintain a regular diet; don’t go on crash diets or intense weight-loss regimes.
Consuming too much alcohol overworks the excretory system, causing skin to age faster, consequently leading to the premature surfacing of wrinkles.

Women tend to develop more wrinkles around their mouths than men do. That may be because women have fewer sweat glands and glands that secrete an oily matter known as sebum (sebaceous glands) to lubricate the skin and fewer blood vessels in this area.Nutritional deficiencies are believed to contribute to skin aging or wrinkles.

Wrinkles


As you age wrinkles settle on your skin. This is nature. Your skin would have a tendency to loosen and show up wrinkles all over. Women worry about this to a greater extent than men. The wrinkles tend to make people look older with age.

Wrinkles are lines or creases on the surface of your skin. They are a natural part of aging. But even young people's skin can develop wrinkles if it's damaged by too much sun or by smoking.

Normal healthy skin has a nice epidermis with a smooth cornified, or outer, layer that acts as a good barrier to water and environmental injury. Skin color and tone is even and unblemished. Components such as collagen (which provides skin firmness), elastin (which supplies skin elasticity and rebound) and glycosaminoglycans or GAGs (which keep the skin hydrated) are all abundant. It is interesting to note that under a microscope a biopsy of a wrinkle exhibits no telltale signs that reveal it to be a wrinkle. So what causes the skin to look wrinkled? It is probably a multi-factorial process of intrinsic aging and extrinsic aging.

Intrinsic aging is the natural aging process that takes place over the years regardless of outside influences. After the age of 20, a person produces about 1 percent less collagen in the skin each year. As a result, the skin becomes thinner and more fragile with age. There is also diminished functioning of the sweat and oil glands, less elastin production, and less GAG formation. Wrinkle formation as a result of intrinsic aging is inevitable, but it will always be slight.
