Young skin lacks wrinkles. Do you know why? Skin of the people who are young does their job effectively in stretching and holding in moisture. The outermost layer in the skin, which is visible to eyes, is called as epidermis. This has got elastic qualities due to presence of fibres called elastin. It keeps the skin fresh and young. Collagen, a type of protein present in dermis also plays a part of preventing wrinkles.
With time dermis looses both elastin and collagen hence skin gets thinner and cis not able to retain enough moisture for epidermis. The fat in the subcutaneous layer that gives skin a plump appearance also begins to disappear, the epidermis starts to sag, and wrinkles form.
So, why do some people in there 50 and 60 too do not get wrinkles? This is only because they have taken special care of their skin in the early parts of their life. Another reason is that their skin might have more sebum, the natural oil of the skin. Wrinkles also depend on the genes. Sooner or later everyone is going to get wrinkles, as it is the part of aging process.
How one should Stop skin wrinkles? Well there are lot of reasons behind wrinkles and lot of remedy too. We would look at few of the ways using which you could delay or Stop skin wrinkles. One of the more accepted techniques to Stop skin wrinkles is plastic surgery. Not only are face-lifts an alternative but also there are now less insidious procedures, like chemical peels, laser healing, and collagen shot. The number one course of action for plummeting wrinkles used today by women of every walk of life is Botox shot. Botox® works by comforting the injected muscle and permit those awful furrow lines and other deep wrinkles to all but fade away. This is impermanent, though, and has to be continual every few months.
Coblation is also an choice for plummeting wrinkles. Less persistent than surgery, radio waves are used to eliminate the top layer of the skin, plummeting the look of fine lines, wrinkles, and sun harm. Although this process does leave you with newer, younger looking skin, it is not as efficient as laser management. It is safer, though, and the healing process is considerably shorter since the radio waves do not go as intensely into the lesser layers of skin.
Even though all of the above mentioned remedies are good alternative, they are also costly in handling and stop skin wrinkles. There are large ranges of wrinkle plummeting creams on the market today that include ingredients like Retinal. These will facilitate to firm your skin and minimize the gaze of fine lines, but not essentially the deeper set wrinkles.

wrinkles usually form as the elasticity of our skin becomes less. it also can be enhanced by weight loss, another way skin loses elasticity is to stretch it and shrink it. while the skin does form new cells, its shape is determined by age and weight, as well as other factors including where u live.

Wrinkles and fine lines are the most easily visible signs resulting from the obstacle course the skin has to face. Helped along by the sagging of the tissues, these wrinkles and lines result in the formation of a type of canvas covered with cracks of varying depths. As time goes by, they deepen, reaching the dermis, which is the skin’s supporting mattress. When the dermis loses its elasticity, it becomes slack and deeper wrinkles begin to form. These wrinkles are more than 0.05 millimetres in depth, therefore they are the longest and widest.
Normal ageing leads to the formation of skin wrinkles. As the years go by, the elastic fibres that keep the skin taut begin to loosen. This makes the skin sag. Wrinkles are also caused by facial expressions, such as the frown lines that form between eyebrows. How much sagging and how many movement wrinkles wrinkles you get depend in part upon your heredity. Most wrinkles, however, are caused by cumulative exposure to the ultraviolet rays of the sun. There are two types of ultraviolet rays: UltraViolet A and UltraViolet B. UVA is associated with skin tanning, wrinkles and melanoma, a form of skin cancer. UVB is associated with sunburn, basal and squamous cell carcinoma; two other forms of skin cancer.
There are three different types of wrinkles: Fine lines occurring throughout the face due to gradual loss of elasticity; Expression lines where the muscles of facial expression cause permanent creases; Gravity lines as the tissues of the face sag a little forming furrows between.
Although people may have a genetic predisposition to severe wrinkling, it is known that sun exposure promotes and exacerbates wrinkling of the skin. Smoking may also negatively affect the skin.
Ageing Process
As a person ages, skin cells divide more slowly, and the inner skin, or dermis, starts to thin. Fat cells beneath the dermis begin to atrophy, and the underlying network of elastin and collagen fibres, which provides scaffolding for the surface layers, loosens and unravels. Skin loses its elasticity; when pressed, it no longer springs back to its initial position but instead sags and forms furrows. The skin's ability to retain moisture diminishes; the sweat and oil-secreting glands atrophy, depriving the skin of their protective water-lipid emulsions. As a consequence, the skin becomes dry and scaly. In addition, the ability of the skin to repair itself diminishes with age, so wounds are slower to heal.
Frown lines (those between the eyebrows) and crow's feet (lines that radiate from the corners of the eyes) appear to develop because of persistent small muscle contractions. Habitual facial expressions also form characteristic lines, contributing to the formation of jowls and drooping eyelids. Skin loses its elasticity.

The sweat- and oil-secreting glands atrophy, depriving the skin of their protective water-lipid emulsions. The skin's ability to retain moisture then diminishes and it becomes dry and scaly.

Habitual facial expressions also form characteristic lines. Gravity exacerbates the situation, contributing to the formation of jowls and drooping eyelids. (Eyebrows, surprisingly, move up as a person ages, possibly because of forehead wrinkles.)
Sun Damage (Photoageing)
The skin can also age prematurely as a result of prolonged exposure to ultraviolet (UV) radiation emanating from the sun (called extrinsic or photoageing). The role of the sun cannot be overestimated as the most important cause of ageing skin and skin cancers. Overall, exposure to ultraviolet (referred to as UVA or UVB) radiation from sunlight accounts for about 90% of the symptoms of premature skin ageing, and most of these effects occur by age 20. Both UVA and UVB rays cause damage leading to wrinkles, lower immunity against infection, ageing skin disorders, and cancer. Even small amounts of UV radiation damage collagen fibres (the major structural protein in the skin) and cause accumulation of abnormal elastin (the protein that causes tissue to stretch). During the process, large amounts of enzymes called metalloproteinases are produced. The normal function of these enzymes is to remodel the sun-injured tissue by synthesising and reforming collagen. This is an imperfect process, however, and to achieve it, some of these enzymes actually degrade collagen. The result is an uneven formation (matrix) of disorganised collagen fibres called solar scars. If this process of imperfect skin rebuilding occurs over and over, wrinkles result. Sunlight damages collagen fibers (the major structural protein in the skin) and causes accumulation of abnormal elastin (the protein that causes tissue to stretch). In response to this sun-induced elastin accumulation, large amounts of enzymes called metalloproteinases are produced. (One study indicated that when people with light to moderate skin color are exposed to sunlight for just five to 15 minutes, metalloproteinases remain elevated for about a week.) The normal function of these metalloproteinases is generally positive, to remodel the sun-injured tissue by manufacturing and reforming collagen. (They may even have factors that protect against melanoma, although this is not clear.)
Other Factors
Other environmental factors, including cigarette smoke and pollution, particularly ozone, may hasten ageing by producing oxygen-free radicals. These are particles produced by many of the body's normal chemical processes; in excessive amounts they can damage cell membranes and interact with genetic material, possibly contributing to the development of a number of skin disorders, including wrinkles and, more importantly, cancer. Rapid weight loss can also cause wrinkles by reducing the volume of fat cells that cushion the face. This not only makes a person look gaunt, but can cause the skin to sag. Air pollution. Ozone, a common air pollutant, may be a particular problem for the skin. One study reported that it might deplete the amount of vitamin E in the skin; this vitamin is an important anti oxidant. Rapid weight loss can also cause wrinkles by reducing the volume of fat cells that cushion the face. This not only makes a person look gaunt, but can cause the skin to sag.
