Hot Topic in Dermatology … Introducing our new “superscreens”

Hot Topic in Dermatology … Introducing our new “superscreens”

Skin aging can be divided into two categories, intrinsic and extrinsic aging. Intrinsic aging is determined genetically and reflects the naturally occurring process that occurs with chronological age. There is not much that we can do as your cosmetic providers to combat this type of inevitable aging. Extrinsic aging on the other hand is the result of several interactions with environmental factors, most importantly being the SUN. “Photoaging” is a popular term that was coined in the 80’s to describe the negative effects that chronic UV exposure have on the skin. With UV exposure we see changes in the skin such as dry rough texture along with skin laxity, pigment changes, redness, visible blood vessels, deep creases and wrinkles.

Traditionally studies have shown the negative effects that UVA and UVB play in the role of aging skin as well as the potential for skin cancer. As sunscreens have evolved, we now notice that many will say broad spectrum meaning that they protect against UVA and UVB damage. What we have failed to consider until recently is the effects that other wavelengths of light can contribute. There is a growing body of knowledge that now recognizes the damaging effects caused by infrared (IR) and visible light. Solar IR is the actual heat that you feel from the sun. When skin temperatures are raised for a long period of time we see similar changes in the skin that are associated with photoaging. Therefore contributing to the ideas that thermal-aging or premature aging can be induced by heat causing destruction of collagen in elastin. So now that we have all this new information … what next?

A new category of sunprotection is now beginning to evolve … “superscreens”! Companies are now looking for a new approach to sunscreens with the most comprehensive protection and active ingredients. We are so excited at USF Health Cosmetic and Laser Center to carry the latest in sun protection with SkinMedica’s® Total Defense + Repair and Colorescience’s® Even-Up. These products not only contain the best UVA/UVB protection but they also contain specialty antioxidant blends to provide protection against IR. They not only protect but Total Defense + Repair minimizes inflammation and promotes the skin’s ability to restore itself. There are options for tinted or non-tinted depending on your preference. Don’t hesitate, come see us today and let us help you provide your skin with the ultimate sun protection from the experts here at the USF Health Cosmetic and Laser Center.

Rejuvenation Prejuvenation

Rejuvenation PreJuventaion

Often patients come to our office seeking skin REjuvenation. These are male and female patients alike, typically in their 40-50’s that have been exposed to the Florida sun for a number of years and some even may be guilty of the ‘ol baby oil and iodine trick in order to get a suntan. We know that at about age 40 several ageing phenomena start to take place in the face. It is common to start to see “bags” under the eyes as the eye socket begins to recede making us look “sunken”. Additionally, wrinkles of motion start to appear at rest from being overused for several decades and actually become little etched in scars. There is a shift that takes place of our facial fat pads that can often exaggerate the lines around the nose and mouth creating a void or loss of volume. You may be starting to think to yourself that this is painting quite a grim picture. With a competitive job market and the baby boomers coming of age we see an influx of patients inquiring about cosmetic procedures.

It is interesting to note that the American Society of Plastic Surgeon Statistics show that injectables like dermal filler for instance has increased steadily anywhere from 5-10% yearly and continues to trend even higher.  What is even more interesting to note is the new group of patients that are coming to our offices seeking what we like to call “pre-juvenation”. These are young women and men in their 20-30’s that can see into the future by looking at their parents and quite frankly may not like what they see. These patients come seeking interventions that they can do to prevent the signs of aging hence we call it “pre-juvenation”.

There are several procedures that are appropriate for the younger generation that wish to be more proactive in their skin’s appearance that was not available to generations before them. Immediately one very popular cosmetic treatment comes to mind, the use of neuromodulators such as Botox, Xeomin, and Dysport. We often hear in the office from a 50 year old patient, “I am not old enough for Botox”. In reality, neuromodulators such as Botox are actually preventative in nature. Understanding the science behind these injectables is crucial to knowing their role in preventing the aging face. This is a product injected into a muscle that is responsible for making a wrinkle. Days after the injection this muscle becomes weaker and unable to make the expression responsible for giving us a wrinkle!  Starting an intervention such as Botox early will literately hault the progression of aging. Most commonly patients are injecting in between the brows for the scowl lines and around the eyes in the area we refer to as the crow’s feet. Studies involving identical twins, one using Botox and one not for over 10 years yield remarkable results that attest to pre-juvenation.

So what else can patients do in the “pre-juvenation” realm? We always recommend starting on a good topical skincare regiment that includes active ingredient products such as retinols, antioxidants, moisturizers and of course a broad spectrum physical sunblock. Retinols slow the age related loss of important skin components while boosting collagen. Antioxidants slow down and prevent the effect of free radicals from the inside out. Other popular interventions that are appropriate for this age group are non-ablative laser and radiofrequency treatments that stimulate collagen with hopes to replenish collagen before it starts to steadily degrade. Chemical peels are also a great way to stay ahead and keep your skin looking youthful and radiant.

Waiting to see a wrinkle develop will put you behind the game in terms of aging. As the vast body of knowledge in cosmetic dermatology continues to grow we certainly see a trend of starting early. Even though we are speaking about patients in their 20-30’s it is never too late to start to pre-juvenate.

Always trust your skin to the experts, come see us at the USF Health Cosmetic and Laser Center to start your pre-juvenation today … after all it is where beautiful skin happens.

THE SUNSCREEN AND VITAMIN D DILEMMA

THE SUNSCREEN & VITAMIN D DILEMMA:  WHATS IS ALL ABOUT?

Sunscreens prevent skin cancer. Some epidemiologic data suggest low levels of vitamin D may increase susceptibility to internal cancer as well as infection, hypertension and autoimmune disorders. Since the sun stimulates production of vitamin D precursors in the skin while sunscreens reduce production it is speculated some of us could be vitamin D deficient and thus at risk for these disorders. Are you now thinking of tossing out your sunscreens and going to the beach or purchasing a package of tanning parlor visits? Hold on! This confusion is a classic example of a “little knowledge is a dangerous thing”.

We have known for many years that sunscreens prevent sunburn and skin cancer by blocking the UVB rays that vary in intensity throughout the year. We now know that longer, more deeply penetrating UVA rays which account for more the 90% of UV light and stay relatively constant throughout the year also play a role in skin cancer as well as skin wrinkling. This is why dermatologists now recommend the newer generation of “broad spectrum” sunscreens that block both groups of rays. SPF rates the amount of UVB protection and the FDA will soon be releasing a new 4-star UVA rating system to quantity the amount of UVA protection. For day to day use (unless you work out of doors or plan recreational sun exposure) a SPF 15 is more than sufficient for most of us. Unfortunately, some commit “sunscreen abuse”, meaning they now go out much longer than before with the false expectation they are getting no sun damage. They may rationalize that by increasing to a SPF 30 they have doubled their protection. Not so fast! A SPF 15 sunscreen blocks 93% of UVB rays, while a SPF 30 blocks 97%–not much additional protection for the increased cost and irritancy!

A few years ago, some studies disclosed a relationship between internal cancer (esp. colorectal cancer) and vitamin D deficiency. In other words, vitamin D perhaps served a “protective” role and since suncreens and/or strict sun avoidance  reduced vitamin D production it was speculated by some and politicized by others as a rational to abandon photoprotection altogether. Making matters worse, some suggested that the vast majority of Americans were vitamin D deficient, while others stated the daily recommendation for vitamin D was too low. Some are now promoting increased sunbathing and utilization of tanning salons, despite the mounting evidence that UVA (the light rays emitted by tanning salons) causes skin cancer, in particular, melanoma and premature aging.

Many subsequent studies assessing the role of vitamin D in “protecting” against internal cancer have conflicting results and it will take many years with long-term prospective studies to know for sure. As well, there is controversy regarding the extent, if any, of significant vitamin D deficiency in Americans. Nonetheless, you can obtain vitamin D from diet (e.g. salmon, fortified milk and orange juice) without subjecting yourself to the risk of sun exposure. The National Institutes of Health claims it doesn’t take much sunlight to make adequate vitamin D-likely as little as 30 minutes twice a week without sunscreen!. Alternatively, simply taking supplemental vitamin D (1,000 IU) if you have had skin cancer, are at risk for skin cancer, or simply want to avoid the unsightly wrinkling and discoloration caused by habitual sun exposure is a much safer way to assure adequate levels. My closing recommendation is moderation and see your dermatologist annually!
