Avobenzone


Avobenzone (also known as Parsol 1789) is an ingredient used in sunscreen products to absorb both UVA and UVB rays. Its ability to absorb ultraviolet light over a wider range of wavelengths than many organic sunscreen agents has led to its use in many commercial preparations marketed as "broad spectrum" sunscreens.

Change your beauty destiny
From Shape, 2/1/05 by Sally Wadyka

It's the classic nature-versus-nurture debate: Is it your genes or your lifestyle that determines how you look as you age? "The rule of thumb in terms of wrinkles is that it's 10 percent genetics and 90 percent environment and lifestyle," says Tina Alster, M.D., of the Washington Institute of Dermalogic Laser Surgery, in Washington, D.C. What is genetic: skin thickness (which accounts for how much it sags) and wrinkle patterns.

The good news: The remaining 90 percent gives you a lot of control. To prove it, Darrick Antell, M.D., a plastic surgeon in New York City, studied identical twins and found that if their lifestyles were the same, their faces aged similarly. But if their habits were different, the contrasts were dramatic. Antell found one sister, who was a sun worshipper (and had premature aging) and the other who wasn't. "Seeing their photos side by side was like looking at plastic surgery before-and-after pictures," Antell says. So while your DNA may be immutable, what you do with its blueprint is up to you. Here, the lifestyle changes that will help you save face.

Protect yourself from the sun. The experts agree: The sun is, hands down, your skin's worst enemy. Exposure to the sun's ultraviolet (UV) radiation causes the skin's support structures (collagen and elastin) to break down, accelerating the aging process. "There are many habits that can age the skin, but the sun really trumps everything else," says Nancy Silverberg, M.D., a dermatologist in Newport Beach, Calif. "And even if you've already done a lot of damage, it's never too late to start wearing sunscreen. Daily use has been shown to actually reverse a significant portion of sun damage." And, it's not enough just to wear it; you need to wear the right one.

"Look for sunscreens that contain ingredients such as zinc oxide, titanium dioxide and Parsol 1789 [also called avobenzone], which all partially block aging ultraviolet-A [UVA] rays," recommends Cherie Ditre, M.D., director of the Cosmetic Dermatology & Skin Enhancement Center at the University of Pennsylvania School of Medicine, in Radnor. Best bet: Clinique Superdefense Triple Action Moisturizer SPF 25 ($40; clinique.com), which uses avobenzone to protect against UVA rays, and the ingredients octinoxate and oxybenzone to fend off burning UVB rays. It's available for oily, regular and dry skin.

Put out that cigarette. Smokers often end up with telltale lines around their lips (created by repeated lip puckering while inhaling), but the damage doesn't stop there. Silverberg points to a study of smokers that found they also were more likely than their nonsmoking counterparts to have significant lines around their eyes. Like sun exposure, smoking breaks down collagen and elastin, speeding up the rate at which skin sags and wrinkles. To help reduce the damage, try Estee Lauder Perfectionist Correcting Concentrate for Lip Lines ($35; esteelauder.com), which helps fill in wrinkles and keep lipstick in place.

Stop making faces. Think of your skin as being like the soft, fine leather of an expensive shoe. Just as the creases in the leather get deeper as you walk in the shoe, your skin reacts in a similar fashion to repeated facial expressions. "Years of constantly using those muscles causes the skin to get a crack, or wrinkle, in it," Antell explains. Botox is often used to soften expression lines (since it paralyzes the guilty muscle, you can no longer make the expression that's causing the wrinkle). A less expensive option: Break the habit. "You can learn not to make certain facial expressions, such as squinting or scowling," says New York City dermatologist Dennis Gross, M.D., author of Your Future Face (Viking, 2005). "Those are behavioral." Make a conscious effort to relax your face when you find yourself drawing your brows together or grimacing. Or apply a topical product to help relax the wrinkles; try Avon Anew Clinical Deep Crease Concentrate ($32; avon.com), which uses a patentpending relaxant called portulaca, or Nuxe Creme Nirvanesque ($41; sephora.com), which uses the botanicals blue lotus, poppy and althea to help relax the contraction of facial muscles.

Control stress. The effect of stress on the body has been well documented: It can compromise the immune system and weaken your ability to fight off illness. Your skin suffers too. When your stress level goes up, your body goes into fight-or-flight mode. More specifically: "Capillaries shrink, and blood flow to the skin decreases as the body redirects blood to the internal organs," your body's way of preparing to defend itself, Antell explains. In addition, chronic stress can increase tension lines on the face and, if it impairs your sleep, you risk a further speeding up of the aging process (see below). In addition to learning how to reduce the anxiety in your life, you can also apply skin-care products to help reinvigorate your complexion. Try Caudalie Vinosource Riche Anti-Wrinkle Cream ($50; caudalie.com) with grapeseed extract to moisturize and protect against age-accelerating free radicals (highly reactive oxygen molecules created by smoking, pollution and sunlight that speed up the aging process); 3Lab Hydrating-Vita Cream with the powerful antioxidant coenzyme Q10 ($120; 3lab.com) and Biotherm Line Peel ($40; biotherm-usa.com), which increases the skin's natural cell turnover process.

Get your beauty sleep. When you look in the mirror after a sleepless night, you're getting a preview of how your face may look in a decade or so. Fine lines will appear deeper; slight under-eye bags will look puffier. "When people are sleep-deprived, they look older and more haggard, especially around the eyes," Alster says. During sleep your body repairs itself, and you get an increase in circulation to the face; without quality sleep, the face sags and shadows appear under the eyes. The good news: The effect can usually be reversed by going to bed earlier the next night and keeping your sleep schedule as regular as possible. Before bed, apply Therapy Systems Retinol Cellular Treatment Cream/PM ($68; therapysystemsinc.com) with retinol and glycolic acid to help repair and exfoliate skin; American Beauty Uplifting Firming Eye Cream ($22.50) and Beauty Boost Overnight Radiance Cream ($27; both at kohls.com), which moisturize and firm as you sleep; or Nivea Visage Q10 Advanced Wrinkle Reducer Night Creme ($11; at drugstores) with the antioxidant coenzyme Q10.

Feed your face. It's commonly said that you are what you eat, and it might also be true that your looks are a direct reflection of your diet. Antioxidants (especially vitamins C and E) may help boost the skin's power to fight free radicals. There's also some evidence that omega-3 fatty acids (found in fatty fish like salmon) reduce inflammation and improve skin texture.

Equally important is what not to ingest: alcohol and sodium. Alcohol dilates capillaries and makes them more fragile (making your face look flushed, bruised or splotchy), and salt causes skin to retain water (think: swollen eyes and cheeks). Put the two together (in, say, a sushi dinner where you consume lots of soy sauce and sake) and you're going to wake up looking bloated. You can help feed your face topically with these editor's picks: IS Clinical Vitamin C Super Serum ($115; isclinical.com) with stabilized L-ascorbic acid, a potent topical vitamin C that works as a powerful antioxidant and anti-inflammatory agent, and Chanel Precision Hydramax + Serum Intense Moisture Boost ($65; gloss.com), with vitamins [B.sub.5], E and F to help protect against free radicals.

Believe in miracles. "We live in a golden age of ingredients," Gross says. "Even if you're genetically destined to have the same aging patterns as your mother, you have access to modern ingredients that can help build collagen, more effective sunscreens to protect against ultraviolet radiation and cosmetic procedures that can undo what you've inherited." He recommends consistently using modern "miracle" ingredients such as the antioxidant vitamins C and E, lycopene and green-tea extract (to fight free-radical damage), retinoids or genistein (to build collagen and elastin) and alpha- or beta-hydroxy acids (to speed skin cell turnover). Best product bets: Prevage Antioxidant Cream ($100; prevage.com) with idebenone, an ingredient that helps repair skin cells; Neutrogena Visibly Firm Lift Serum ($19; at drugstores), with concentrated active copper to restore firmness; L'Oreal Transformance Skin Perfecting Solution ($16.59; at drugstores), an oil-free serum with vitamin C to hydrate and protect; and CelGen Age Repair Moisture Solution ($45; stc biotech.com), a toner that hydrates and promotes skin renewal.

How the latest injectables can turn back time

Dermatologists Leslie Baumann, M.D., of the University of Miami Cosmetic Center, and Lynne Haven, M.D., of Greenwich, Conn., explain how the newest fillers work. (The cost of each ranges from $600-$900, depending on the area of the country in which you live and how much filler is needed.)

Hylaform Derived from hyaluronic acids extracted from rooster combs, Hylaform is best for plumping up lips, cheeks and jaw line. Results last four to six months. Downside: Because it's a filler, it can cause bruising.

Isolagen This is an innovative filler that's created from skin taken from behind the ear of the patient. Six weeks after the skin cells are stimulated to reproduce in a lab, a doctor injects them into wrinkles and depressions, where they continue to reproduce and create new collagen. Results are seen three weeks after injection and appear to last longer than collagen. The upside: There's less risk of adverse reactions because it's made from your own tissue. Downside: There's no immediate gratification.

Juvaderm A hyaluronic gel currently undergoing clinical trials, it reportedly gives a very smooth effect (with less risk of inflammation). Downside: As with any filler, it can cause bruising.

Restylane A synthetic version of hyaluronic acid, a substance naturally found in the skin, Restylane works well for filling or smoothing wrinkles. Results typically last four to six months. Downside: As with any filler, it can lead to swelling and redness.

Sculptra This injectable is used off-label for contouring (plumping up sunken cheeks or other large areas). Injected deeper into the skin than the conventional line-fillers (usually in a series of treatments over several months), Sculptra lasts up to two years. Downsides: Results aren't instantaneous, and because it's hard to learn to use correctly, some undertrained doctors may leave patients with bumps and other unnatural-looking effects.

Readers share what they learned from their moms about what to do (or not to do) for their skin with regard to aging:

RELATED ARTICLE: Predicting how and where you will age

In his new book, Your Future Face (Viking, 2005), New York City dermatologist Dennis Gross, M.D., explains how to foresee your beauty destiny. He suggests making notes of the particular risks that seem to apply to you so that you can create a customized skin-care plan targeting your skin's vulnerabilities.

* Look at family members to see if there are shared traits, such as brow furrows, crow's-feet or under-eye bags. Also, studying the parent you most closely resemble can help forecast how you'll look when you're older--but don't forget that lifestyle factors can have a profound effect on speeding up or slowing down the aging process.

* Notice how you look when you are expressionless versus when you are showing emotion. There's a strong possibility that the lines or furrows that only appear right now when you squint, concentrate or are tense, will become permanent later in life.

* When you're exhausted, your face reflects your areas of vulnerability, such as skin laxity around the mouth or the deepening of old acne scars on the cheeks. As you age, your skin will have less regenerative power, so these flaws may become more apparent.

* Areas on your skin that appear crinkly though not quite lined or wrinkled--either all the time or just when pinched--usually indicate areas that have sustained more sun damage that the rest. Over time there's a strong possibility that these regions will morph into lines or wrinkles or start to sag.
