Now you don’t even have to wait to be 40 to notice the first fine lines around your eyes, or between your forehead. Blame it on the lifestyle, the environment, the stress but girls as young as 25 are complaining of haggard skin, and faint creases. Who wants to look older than they really are? Not anybody I suppose. We all want radiant skin that looks fresh all the time. But to get that you have to first understand the skin aging process in detail and the role of various factors in prevention of aging. The subject of skin aging is indeed a very complex one with host of internal and external factors responsible for the aging process. Aging caused by the genes we inherit is called intrinsic (internal) aging. The other type of aging is known as extrinsic (external) aging and is caused by various factors such as exposure to the sun’s rays, pollution, stress, nutrition etc.
Intrinsic aging, also known as the natural aging process, is a continuous process that normallybegins in our mid-20s. Within the skin, collagen production slows, and elastin, the substance that enables skin to snap back into place, has a bit less spring. Dead skin cells do not shed as quickly and turnover of new skin cells may decrease slightly. The signs of intrinsic aging include dry and thin skin, fine wrinkles, abnormal blood vessels, age spots and blemishes, rough thick skin, sagging, and skin cancer. So if you want to really deal with this natural process of aging then you will have to look into a variety of key issues including collagen replacement, strengthening the vascular walls of small blood vessels that supply the skin, increasing vascular supply for oxygenation and detoxification purposes, dilution of pigment to lighten age spots, increasing immunity to reduce cancer risks, and reducing oxidative damage to
A number of extrinsic, or external, factors often act together with the normal aging process to prematurely age our skin. This is the most worrisome problem for women today. Most premature aging is caused by sun exposure. Other external factors that prematurely age our skin are repetitive facial expressions, gravity, sleeping positions, nutrition, and smoking.
The Sun: Without protection from the sun’s rays, just a few minutes of exposure each day over the years can cause noticeable changes to the skin. Freckles, age spots, spider veins on the face, rough and leathery skin, fine wrinkles that disappear when stretched, loose skin, a blotchy complexion and skin cancer can all be traced to sun exposure.
“Photoaging” is a type of aging caused by exposure to the sun’s rays.
Photoaging occurs over a period of years. With repeated exposure to the sun, the skin loses the ability to repair itself and the damage gets accumulated. Repeated UV exposure breaks down collagen and impairs the synthesis of new collagen. The skin ceases to spring back and becomes loose, wrinkled and leathery much earlier.
Facial Expressions: Repetitive facial movements actually lead to fine lines and wrinkles. Each time we use a facial muscle, a groove forms beneath the surface of the skin, which is why we see lines form with each facial expression.
Gravity: Gravity constantly pulls on our bodies. Gravity causes the tip of the nose to droop, the ears to elongate, the eyelids to fall, jowls to form, and the upper lip to disappear while the lower lip becomes more pronounced.
Sleeping Positions: Resting your face on the pillow in the same way every night for years on end also leads to wrinkles. Called sleep lines, these wrinkles eventually settle on the surface of the skin.
Smoking: Cigarette smoking causes biochemical changes in our bodies that accelerate aging. Also smoking depletes your skin of vitamin C and other antioxidants, which speeds up aging. These signs can be greatly diminished, and in some cases avoided, by stopping smoking.
