why does your skin wrinkle when you age?

Answer 1

As you age, your skin loses its elasticity. That is also a reason why when your still young, its very important to put cream on, because the cream will smoothh out within your skin's natural crease, forming a more smoot youthful look. Its also because if theres no cream or some sort of moisturizer, the skin will dry out really bad, leaving more deeper inprints of crease on your skin, et voila, wrinkles. Hope that helped, and take care!

Answer 2

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(glycosaminoglycans) formation. Wrinkle formation as a result of intrinsic aging is inevitable, but it will always be slight.
Extrinsic aging occurs in addition to intrinsic aging as a result of sun and environmental damage (tobacco use and exposure to pollution, for example). Extrinsic aging shows up as thickening of the cornified layer, precancerous changes such as lesions called actinic keratosis, skin cancer (including basal cell carcinoma, squamous cell carcinoma, lentigo maligna melanoma), freckle and sun spot formation, and exaggerated loss of collagen, elastin, and GAGs. Alone or in concert, these processes give the skin the appearance of roughness, uneven tone, brown patches, thin skin and deep wrinkles

Answer 3

All the body tissues become thinner with age, and the organs shrink.
The skin is the body's largest organ. Yes, the skin IS an organ!
As the skin gets thinner and holds less moisture and collagen, it loses elasticity and wrinkles.

Answer 4

With aging, the outer skin layer (epidermis) thins even though the number of cell layers remains unchanged.

The number of pigment-containing cells (melanocytes) decreases, but the remaining melanocytes increase in size. Aging skin thus appears thinner, more pale, and translucent. Large pigmented spots (called age spots, liver spots, or lentigos) may appear in sun-exposed areas.

Changes in the connective tissue reduce the skin's strength and elasticity. This is known as elastosis and is especially pronounced in sun-exposed areas (solar elastosis). Elastosis produces the leathery, weather-beaten appearance common to farmers, sailors, and others who spend a large portion of their life outdoors.

The blood vessels of the dermis become more fragile, which in turn leads to bruising, bleeding under the skin (purpura), cherry angiomas, and similar conditions.

Sebaceous glands produce less oil as you age. Men experience a minimal decrease, usually after 80 years old. Women gradually produce less oil beginning after menopause. This can make it harder to keep the skin moist, resulting in dryness and itchiness.

The subcutaneous fat layer, which provides insulation and padding, thins. This increases your risk of skin injury and reduces your ability to maintain body temperature. Because you have less "natural insulation" and in cold weather, hypothermia can result.

Some medications are absorbed by the fat layer, and loss of this layer changes the way that these medications work.

The sweat glands produce less sweat. This makes it harder to keep cool, and you become at increased risk for becoming overheated or developing heat stroke.

Growths such as skin tags, warts and other blemishes are more common in older people.
