Research shows that there are, in fact, two distinct types of aging.

> 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 environmental factors, such as exposure to the sun’s rays.

Intrinsic Aging

Intrinsic aging, also known as the natural aging process, is a continuous process that normally begins 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. While these changes usually begin in our 20s, the signs of intrinsic aging are typically not visible for decades. The signs of intrinsic aging are:
> Fine wrinkles
> Thin and transparent skin
> Loss of underlying fat, leading to hollowed cheeks and eye sockets as well as noticeable loss of firmness on the hands and neck
> Bones shrink away from the skin due to bone loss, which causes sagging skin
> Dry skin that may itch
> Inability to sweat sufficiently to cool the skin
> Graying hair that eventually turns white
> Hair loss
> Unwanted hair
> Nail plate thins, the half moons disappear, and ridges develops

Genes control how quickly the normal aging process unfolds. Some notice those first gray hairs in their 20s; others do not see graying until their 40s. People with Werner’s syndrome, a rare inherited condition that rapidly accelerates the normal aging process, usually appear elderly in their 30s. Their hair can gray and thin considerably in their teens. Cataracts may appear in their 20s. The average life expectancy for people with Werner’s syndrome is 46 years of age.

Extrinsic Aging

A number of extrinsic, or external, factors often act together with the normal aging process to prematurely age our skin. Most premature aging is caused by sun exposure. Other external factors that prematurely age our skin are repetitive facial expressions, gravity, sleeping positions, 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, actinic keratoses (thick wart-like, rough, reddish patches of skin), and skin cancer can all be traced to sun exposure.

“Photoaging” is the term dermatologists use to describe this type of aging caused by exposure to the sun’s rays. The amount of photoaging that develops depends on: 1) a person’s skin color and 2) their history of long-term or intense sun exposure. People with fair skin who have a history of sun exposure develop more signs of photoaging than those with dark skin. In the darkest skin, the signs of photoaging are usually limited to fine wrinkles and a mottled complexion.

Photoaging occurs over a period of years. With repeated exposure to the sun, the skin loses the ability to repair itself, and the damage accumulates. Scientific studies have shown that repeated ultraviolet (UV) exposure breaks down collagen and impairs the synthesis of new collagen. The sun also attacks our elastin. Sun-weakened skin ceases to spring back much earlier than skin protected from UV rays. Skin also becomes loose, wrinkled, and leathery much earlier with unprotected exposure to sunlight.

People who live in sun-intense areas, such as Florida or Arizona, can show signs of photoaging in their 20s. In fact, some people who live in sun-intense areas develop actinic keratoses (AKs) and skin cancer in their 20s.

While it may seem that the signs of photoaging appear overnight, they actually lie invisible beneath the surface of the skin for years. UV photography enables us to see the damage accumulating beneath the surface of the skin years before the signs of photoaging appear. Most people are surprised by the amount of photoaging that the UV camera shows. To see actual patient photographs that show: 1) what is visible to the naked eye and 2) what damage lies beneath the surface, visit:

UV Photography Reveals Sun Damage

Facial Expressions

If you perform facial exercises to maintain a youthful-looking appearance, it is time to stop. 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. As skin ages and loses its elasticity, the skin stops springing back to its line-free state, and these grooves become permanently etched on the face as fine lines and wrinkles.

Gravity

Gravity constantly pulls on our bodies. Changes related to gravity become more pronounced as we age. In our 50s, when the skin’s elasticity declines dramatically, the effects of gravity become evident. 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 become etched on the surface of the skin and no longer disappear when the head is not resting on the pillow. Women, who tend to sleep on their sides, are most likely to see these lines appear on their chin and cheeks. Men tend to notice these lines on the forehead since they usually sleep with the face pressed face down on the pillow. People who sleep on their backs do not develop these wrinkles since their skin does not lie crumpled against the pillow.

Smoking

Cigarette smoking causes biochemical changes in our bodies that accelerate aging. Research shows that a person who smokes 10 or more cigarettes a day for a minimum of 10 years is statistically more likely to develop deeply wrinkled, leathery skin than a nonsmoker. It also has been shown that people who smoke for a number of years tend to develop an unhealthy yellowish hue to their complexion. Additionally, a study conducted in 2002 showed that facial wrinkling, while not yet visible, can be seen under a microscope in smokers as young as 20. These signs can be greatly diminished, and in some cases avoided, by stopping smoking. Even people who have smoked for many years, or smoked heavily at a younger age, show less facial wrinkling and improved skin tone when they quit smoking.

Prevention

While you cannot stop or even slow down the intrinsic aging process, you can prevent signs of premature aging by protecting your skin from the sun, quitting smoking, and eliminating facial exercises.

Dermatologists recommend comprehensive sun protection to prevent premature aging caused by the sun. Comprehensive sun protection includes:
> Avoiding deliberate tanning, including use of indoor tanning devices.
> Staying out of the sun between 10:00 a.m. and 4:00 p.m., when the
sun’s rays are the strongest.
> Wearing protective clothing, such as a wide-brimmed hat and long
sleeves, when outdoors during the day.
> Applying sunscreen year round. Sunscreen should be broad spectrum
(offers UVA and UVB protection) and have a Sun Protection Factor
(SPF) of 15 or higher. Sunscreen should be applied 20 minutes before
going outdoors to all skin that will be exposed. It should be reapplied
after sweating or being in water.

Treatment

If you are bothered by visible signs of aging, a number of treatments are available. Injectable fillers and botulinum toxin are suitable for people with busy lifestyles who do not want the inconvenience of a long recovery. Radiofrequency is a procedure that offers an alternative to the traditional facelift. Dermabrasion, laser resurfacing, chemical peeling, microdermabrasion, and some topical treatments can restore skin, giving it a smoother and refreshed appearance.

Scientific research in the field of anti-aging continues to give rise to new and promising treatment options. A dermatologist can help you sort through the numerous options, including the myriad of over-the-counter products. During a consultation, the dermatologist will examine your skin, discuss your expectations, and recommend suitable treatment options.

Lesson 1: Sun Damage Is the #1 Cause of Aging
Your skin is a visible reminder of your age -- and any fine lines, crow's-feet, or discoloration that crops up as you age are directly related to sun exposure. It's hands-down the number one cause of aging, says dermatologist Marta Van Beek, MD, of the University of Iowa.

Quick Test: Want proof? Dermatologist Carl Washington, MD, the co director of the Dermatological Surgical Unit at the Emory Clinic at Emory University, has an easy test. "I tell my patients to look at skin under their breast or under their armpit, and compare it to their face or shoulders. This unexposed skin is usually in great condition -- it shows that it really is the sun that is aging you," he says. "All of your skin is the same age. If it's altered by your diet or other environmental effects, that skin should be the same as the skin on your face or shoulders."

4 Easy-to-Damage "Hot Spots"

Take Note: Exposed skin on the face is easily the most at-risk area for sunburn, followed closely by the shoulders, hands, ears, and neck. If you want to maintain youthful, resilient, wrinkle-free skin, don't skimp! These areas need special daily attention from a bottle of sunscreen. And don't give up if you do see signs of age in these areas already -- instead, ramp up your skincare regimen starting now. "It's a misquote that all your major skin damage is already done by the time you reach age 18," said Van Beek. "People live much longer now, and taking care of your skin at any age is never a lost cause. Start today."

Quick Test: How can you tell if you're had too much sun? Just press on the skin, says Marshall Brain, the founder of HowStuffWorks.com and author of "How Sunburn and Sun Tans Work." "The extra blood in the capillaries causes the redness," Brain says. "If you press on sunburned skin it will turn white and then return to red as the capillaries refill." If you see this happening, the damage is already done -- but you should still get out of the sun immediately. Avoid this in the future by becoming a sunscreen expert in Lesson 2.

Lesson 2: Better Sunscreen Application
The line between a safe sun exposure and red, painful, sunburned skin is narrow, and Van Beek has seen hundreds of sun-frustrated patients over the years. "They'll constantly tell me, 'I always put on sunscreen, and then I still get burned.'" It's not surprising, she says. Hardly anyone puts on as much sunscreen as they actually need. In her experience, most people put on barely half as much. "Industry tests of sunscreen (which determine its sun-protection value) are done with much more than anyone puts on -- usually gobs and gobs more," says Van Beek.

Take Note: Sunscreen isn't a quick fix. You can still burn even while wearing it. "Sunscreens are filters, not blocks," notes the Photobiology Testing Facility at the University of Sydney in Australia, the self-proclaimed skin cancer capital of the world. (In Australia, 2 out of 3 people suffer some form of skin cancer during their lifetimes, according to the latest estimates.)

How Sunscreen Works: Sunscreens block or absorb the ultraviolet light from the sun. UV rays reach your skin at a rate that depends on the sun protection factor (SPF) listed on the bottle. For example, a sunscreen labeled SPF 30 permits 1/30th of the sun burning energy to hit your skin, versus the time it would take to suffer a minimal sunburn completely unprotected. Given enough time, enough sun burning energy can still penetrate through a sunscreen to burn your skin.
Protect Yourself Outdoors
Memorize these five steps to increase your sunscreen application smarts before moving on to Lesson 3.

1. Aim high, spread wide. Choose a sunscreen with the highest sun protection factor (SPF) you can find, and use at least a teaspoon-size amount for your face, and around an ounce (generally a palmful) to cover your whole body. "On average you'll get about half the SPF listed on the bottle," said Van Beek. For the best protection, spread the lotion from your ankles to your hairline.
2. Read the fine print. Most sunscreens advise applying 15-30 minutes before heading out into the sun, and reapplying every hour or two hours. Don't ignore these directions -- if you do, your protection level can drastically drop. Even long-lasting formulas labeled "water-proof" or "sweat-proof" can lose their protective coating on the skin after swimming or sweating.
3. Check the ingredients. Choose a broad-spectrum sunscreen (which offers both UVA and UVB protection), and look for ingredients such as avobenzone, titanium dioxide, or zinc oxide. Hate the opacity of thick, white zinc oxide? Look for the newer formulations of micronized titanium dioxide, which offer the same protection levels without the ghostly sheen.
4. Double-check the expiration date. Plan to buy a new bottle of sunscreen each year (i.e., the sticky bottle stuffed into your glove compartment is probably way past its prime). Don't guess about the protection an old product might provide -- drop a few bucks on a new tube.
5. Repeat after the Aussies: "Slip, slap, slop." Skin cancer is such a big health problem in Australia that the government-backed skincare slogan "Slip, slap, slop" is a national mantra. Skin-savvy Australians say: "slip" on a shirt, "slop" on sunscreen, and "slap" on a hat. It's catchy (and the American Cancer Society has adopted it too). Plus, you can keep sun safety trendy. Try a wide-brim straw hat --the best have 2 or 3 inches all the way around -- and add polarized sunglasses (even designer shades have this protection now), and your sexy new sarong. And when you can, always grab a seat in the shade.

Lesson 3: Cancer Self-Screening
Self-screening for skin cancer should be a monthly task, according to the American Cancer Society. Take the opportunity to get to know every freckle, bump, and birthmark now, so you can identify any important changes later. And for the record, a normal mole is defined as an evenly colored black, brown, or tan spot on the skin, typically round or oval and flat or slightly raised. Most people have at least a few moles, and usually they're harmless.

Here's what to look for:
For Melanoma Skin Cancer
Know this: Melanoma is the skin cancer that begins in the melanocytes, or the cells that produce melanin (the chemical that darkens your skin in the sun). This type of cancer is curable if caught early, but can be more dangerous than non-melanoma skin cancer.
Protect Yourself: Recite your ABCs...and don't forget D and E
· A is for Asymmetry. Healthy moles are generally symmetrical in shape. Check carefully for any moles where one half doesn't match the other.
· B is for Border. Check to make sure the mole's edges aren't irregular, ragged, notched, or blurred.
· C is for Color. In a potentially cancerous area, the color is lighter is some areas, and can include shades of brown or black, sometimes with red, white, or even blue patches.
· D is for Diameter. If a spot is larger than 6 millimeters across, close to the size of a pencil eraser, or is growing larger, have it professionally checked.
· E is for Evolution. Knowing your family's skin cancer history can help access your risk level. Make sure your doctor knows details about any family members with a history of any sort of skin cancer.
For Non-Melanoma (Basal or Squamous) Skin Cancer:
Know This: This type of cancer develops from any skin cell other than melanocytes -- hence the name. Most skin cancers are non-melanomas -- but an oddly shaped mole is typically not an indicator of the problem.
Protect Yourself: Memorize how to identify a potentially cancerous danger spot.

· Basal Carcinomas: Beware of flat, firm, pale areas of the skin, or raised shiny or waxy-looking areas that can bleed after minor injury. The skin could also have black, brown, or blue areas, or be slightly depressed in the center.
· Squamous Carcinomas: These can appear as a growing lump with a rough surface, or as a flat, red-tinted patch that grows slowly.

Lesson 4: Sunburn Myths
Chances are high your doctor or dermatologist has heard one of these bogus lines (and probably has a finger-shaking speech prepared on each). Spare yourself the lecture -- we asked Washington and Van Beek for the top sunburn myths they've heard from their patients. Brush up on your own sun-care knowledge with their expert advice.

The Myth: "I've got some Italian in me, so I'm naturally protected from the sun."

The Doctor Says: Sorry -- this assumption is completely false. "When I hear a line like this from my patients, I just say, 'I'm African-American and I can still get skin cancer,'" said Washington. "It is the case that the darker the skin, the better protected -- but no one is immune."

The Bottom Line: "No one is immune." The natural melanin in your body, the chemical responsible for your skin color, will only protect you to a point. Anyone, regardless of their natural skin protection, can damage their skin -- so everyone should make daily protection a habit.
The Myth: "Why should I worry? I only damaged my skin as a kid or in college."
The Doctor Says: Even if your days of bikini-clad beachside tanning sessions are long past and you haven't had a sunburn for years, wearing sunscreen daily and taking other protective measures can guarantee healthier skin and possibly a longer life. "Skin cancer is a cumulative effect," said Washington. "You can still benefit from staying skin-smart today."

The Bottom Line: Don't wait until a skin damage scare forces you to take action to protect your skin -- upping your vigilance today will still help you in the future.

The Myth: "Its only skin -- its no big deal."

The Doctor Says: Your skin is the largest organ in your body (yes, it is an organ) and damaging it is a big deal. "When that same patient gets skin cancer on his face and then has to have it cut out, he's usually pretty freaked out," said Van Beek. Scars from removing moles or cancerous growths can be broad (consider having a 3- to 5-inch scar on your face!) depending on how deep the problem patch is.

The Bottom Line: Care for your skin seriously. The more times you damage it with sun exposure, the more chances you have to develop skin cancer.

The Myth: "I've heard I need to be out in the sun to make sure I'm getting enough vitamin D."

The Doctor Says: It is true that sun exposure provides a natural source of vitamin D -- but most people severely overestimate how much they need. "Usually just the exposure you get going to and from work is enough," said Washington. "Most Americans get enough vitamin D from fortified foods to not need it from the sun at all."

The Bottom Line: Fill your daily vitamin D quota through a healthy diet. If you're concerned, take a multivitamin that includes vitamin D.

The Myth: "Tans are healthy."

The Doctor Says: This is a classic myth, and it's absolutely false. There is no such thing as a "safe" tan. But it's a tough line to discredit, says Van Beek. "Tanning does release endorphins, which make you feel happy, and it can make you look thinner." But the payoff is short-lived, she says. And the consequences are fine wrinkling, blotchy skin, and a heightened risk of skin cancer.

The Bottom Line: If you crave a "healthy" glow from a tan, try a self-tanner or bronzing powder. The streaky orange self-tanners are a product of the past, so a "fake bake" looks more natural than ever. As for those feel-good endorphins released by basking in the sun, other activities like exercise, sex, laughter, and eating chocolate also release them -- so choose a safer, skin-friendly alternative.
