"What the Sun Does to Your Skin" By Dr. Nita Patel Nita Patel, M.D., graduated from the UCLA School of Medicine and completed her dermatology residency at the UCLA and VA West Los Angeles Medical Centers. Dr Patel is a diplomate of the American Board of Dermatology and has special expertise in lasers, skin cancer surgery and cosmetic procedures. She serves as faculty and teaches her techniques to physicians at laser courses. Dr. Patel is a Fellow of the American Academy of Dermatology and the American Society for Dermatologic Surgery. She is currently an Assistant Clinical Professor at the UCLA School of Medicine and serves on staff at Centinela and the Daniel Freeman hospitals. The Sun emits two fundamental types of rays that can cause damage to the skin: UVB and UVA radiation. UVB rays of light are responsible for damaging the upper layers of skin, or the epidermis. This is how you get a sunburn. UVB rays also cause changes to the epidermis resulting in age spots, damaged cells and even skin cancer. UVB rays can actually cause damage to the epidermis in as little as three minutes, and is at its peak between 10 a.m. and 2 p.m. This is the most dangerous time to be exposed to sunlight. Of course, we are all exposed to sunlight throughout our lives. Over a 20- to 30-year period, damage simply accumulates. And in some cases, damage which may have occurred when you were young doesn't manifest itself in physical symptoms until 20 or 30 years later. For example, soldiers exposed to extreme sunlight during World War II were found to have a higher incidence of skin cancer in the period of time 20 to 30 years after exposure. Today, we know that use of sunscreen can help minimize this damage. This is the kind of prevention we must all use, even if we are just casually going out in the midday sun for a seemingly brief period of time. I strongly recommend sunscreen to protect your skin on a daily basis. The second type of sunlight important to note are UVA rays. These penetrate deeper into the dermis. This is the layer of skin beneath the epidermis where we find collagen, which serves as the foundation for skin. UVA rays that stimulate pigment-making cells produce a suntan. This is why UVA rays are used in tanning beds. Unfortunately, UVA rays are also harmful and can cause damage we refer to as "photoaging." This results in the formation of wrinkles due to damaged collagen in the dermis. Chronic photoaging can occur as a result of excessive exposure to the sun, even at relatively early ages, or over a longer period of lifetime exposure. All of us experience this nature of damage after a period of 20 to 30 years, and thus wrinkles inevitably appear as we age. It's important to note that UVA damage done to collagen in the dermis cannot be reversed. The collagen destroyed cannot be repaired. It can, however, be replaced by new collagen if the body is stimulated to produce it. This is how NLite™ system for wrinkle reduction through laser collagen replenishment works to reduce wri nkles. It "insults" or mildly stimulates microblood vessels in the dermis, which triggers the body's reaction of natural collagen replenishment. This is a procedure that involved little to no pain and produces a natural healing reaction without damaging the skin. The key is the manner in which the NLite™ laser only insults the blood vessels enough to stimulate the healing process of collagen replenishment. No damage is caused to the epidermis or dermis with NLite™. So while you can't reverse the effects of damage from exposure to the sun, we can cause the body to replenish damaged parts of the skin, such as collagen in the dermis. This is how NLite™ can replace damaged collagen with new collagen. That's how wrinkles can be reduced even after years of exposure to the sun. "Cornerstone of an Anti-Aging Regimen" By Dr. Jeffrey Rapaport Jeffrey Rapaport, M.D., is Medical Director of the Cosmetic Skin and Surgery Center of Fort Lee, and Assistant Chief of Dermatology at Holy Name Hospital. He is a Phi Beta Kappa recipient from Emory University and a graduate of the Emory University School of Medicine in Atlanta, Georgia. After internship at Emory, he completed his advanced training residency at Thomas Jefferson University, where he served as chief dermatology resident. Dr. Rapaport is certified by the American Board of Dermatology and is a Fellow of the American Society for Dermatologic Surgery, Fellow of the American Academy of Aesthetic and Restorative Surgery and the International Society for Dermatologic Surgery. He is a recipient of the American Medical Association Continuing Medical Education Award and the American Academy of Dermatology Award. Dr. Rapaport is the holder of three U.S. Patents for dermatologic products. He has been a leader in aesthetic surgery, and has performed thousands of cosmetic procedures. In the ongoing struggle against the aging process, keeping the skin in good condition usually seems like a Sisyphean task. In addition to the natural toll advancing years takes on the skin, sun exposure, pollution, smoking and stress are constantly causing further damage. Until very recently, the uphill battle to look better has been both expensive and time consuming, based on corrective rather than preventive methods. Used as part of a skin care regimen, NLite™ can effectively help people keep the "rock" of anti-aging at the top of the hill. NLite™ was created to accommodate increasingly busy people who want to cosmetically enhance the skin, but do not have the liberty to take time off for more invasive procedures, such as laser resurfacing or the traditional face lift. Most importantly, it is effective. I have done many procedures, seen good results and patients are satisfied. NLite™ is an effective way to replenish damaged parts of the skin, such as the collagen which contributes to the appearance of wrinkles. "Beyond Photorejuvenation" By Dr. Steven B. Snyder Steven B. Snyder, M.D., is a Board Certified Dermatologist and Cosmetic Laser Surgeon who has been working with surgical lasers since 1984. Having performed over 15,000 laser treatments, Dr. Snyder pioneered the development and use of a diverse range of laser procedures. Dr. Snyder is the first physician in the country to own the new NLite™ system for wrinkle reduction through laser collagen replenishment and, to date, has performed over 1,000 laser treatments for wrinkle reduction with this new technology. He has taught the safe use of lasers to hundreds of physicians in various seminars, instructional courses and workshops. Dr. Snyder has been recognized nationally and internationally for his work in cosmetic laser surgery. He is in private practice as the Director of the Dermatology Laser Center in Owings Mills, Maryland. In the last decade, there have been a variety of new procedures and techniques developed to reverse the damaging effects on the skin from exposure to sunlight. Some of the visible signs of this sun damage include facial wrinkles, pigmented lesions ("age spots") and dilated blood vessels. This article will explore photorejuvenation procedures and NLite™ as two ways to improve the look and texture of sun-damaged skin. Photorejuvenation is a process that may possibly improve the appearance of skin by using light. This process rejuvenates the surface of the skin in a nonablative manner. It works by delivering specific wavelengths of light to stimulate new tissue growth, contraction of collagen fibers and / or damage of unwanted collections of cells. Those who desire an improvement in the look and texture of sun-damaged skin may be candidates for photorejuvenation. People must be willing to undergo a series of treatments to achieve optimal results. Photorejuvenation techniques primarily target the color and texture of skin, and secondarily have an effect on wrinkling or scarring. Only a small percentage of the light used in photorejuvenation techniques has a stimulatory effect on collagen production. NLite™ is a new FDA-cleared, wrinkle reduction therapy that goes beyond photorejuvenation with less risks. Unlike photorejuvenation techniques that primarily focus on the color and texture of skin, NLite™ targets specifically only the collagen layers beneath the skin's surface to reduce wrinkles. It does not change the color of the skin. Instead, the laser stimulates the production of new, natural collagen growth in areas where collagen had been lost or reduced due to aging, thereby decreasing wrinkles from below the skin's surface. With the NLite™ treatment, there is no redness, no burning, no stinging, little to no pain, no anesthetic required, and patients can immediately return to their normal activities following treatment. NLite™ is a noninvasive, safe method to improve the look and feel of the skin without undergoing the pain and downtime associated with deep laser resurfacing or deep chemical peels. With NLite™, there is no risk of color change, textural change or scarring. There is a small percentage of cases where such problems occur with photorejuvenation. NLite™ is the appropriate therapy for people who specifically wish to reduce the appearance of wrinkles. For patients whose primary concern is facial discolorations and who are willing to undergo a series of five to six treatment sessions, photorejuvenation is the appropriate therapy.
