Tis the season to be allergic

The holidays are upon us, and it's time to shower our loved ones with gifts, and receive some in return.  But sometimes those clothes, shoes, jewelry, and beauty products can leave an unwanted present: itching and redness.

It's called an allergic contact dermatitis, and can result from different allergens coming into contact with the skin.  Cortisone creams often alleviate symptoms, but unless the trigger is identified, the rash can reoccur. The location of the rash often gives some clues.  For example, eyelid rashes are commonly caused by nail polish (especially containing formaldehyde) and acrylic nails (the glue contains ethyl methacrylate or methyl methacrylate).  When the trigger is not obvious, patch testing is a useful tool. 

Dermatologists perform patch testing in the office to reveal allergens.  Scratch testing (with needles) is typically done by an Allergist and is used to identify foods or inhlaed allergens (think dust, plants). Patch testing, in contrast, is used to identify allergens that come into contact with the skin.

Patches to the most common allergens (in our office we test 65!) are placed on the back and covered.  Two days later, they are uncovered and the skin is inspected to see if any area reacted to the allergen.  A final reading is done two days after that.  Once the trigger is identified, they can then be avoided in the future.

Common allergens tested include: 

preservatives like methylchloroisothiazinolone and imidazolidinyl urea in cosmetics
thimerosal in contact solution
nickel in metals/jewelry
latex/rubber in gloves
formaldehyde in cleaning agents
chromates in leather
mercaptobenzothiazole in rubber (shoes)
para-phenylenediamine in hair dyes


Keep skin looking healthy, merry and bright!  Happy holidays!

My favorite vitamin

People spend their lives searching for the fountain of youth. Maybe if Ponce de Leon knew about vitamin A cream, he would have saved himself some time...

Being more saavy than poor Ponce, you've probably heard of Vitamin A derivatives, known as retinoids. But with so many different names and variations on the market, it can be confusing. Here's the skinny:

Retinoic acid: this topical form of vitamin A is also called tretinoin. It's available by prescription, and is more effective than over the counter forms. In science speak: retinoic acid works to promote cell turnover and collagen production, and has anti-inflammatory effects. It also enhances the penetration of other topical medications/creams. In beauty speak: it helps lighten brown spots, reduces the appearance of fine lines, smooths skin, treats acne blackheads and helps prevent new ones from developing, and improves the overall appearance of skin. Prescription brand names include: Retin-A, Renova, Atralin, Refissa, Tretin-X, and it's one of the ingredients in the skin lightening cream TriLuma.

Retinol: this is the form found in over the counter (nonprescription) products. In order to be effective, retinol needs to be converted to retinoic acid at the cellular level, and generally takes more time to see results, often as long as 3-4 months.

Except in pregnant or nursing women, retinoids are an integral part of a good skin care routine. Add in the other essentials: a broad-spectrum sunscreen and an antioxidant/growth factor serum, and the fountain may soon appear!

Bruce Jenner's nose

People.com recently revealed that Bruce Jenner has been diagnosed with and treated for skin cancer on his nose.  Click to read article.  The type of skin cancer is called basal cell carcinoma.  It is not a form of melanoma.  It's one of the three types of skin cancer (basal cell carcinoma (BCC), squamous cell carcinoma (SCC), and melanoma).

And it's the most common type of skin cancer, in fact.  According to the Skin Cancer Foundation, an estimated 2.8 million are diagnosed annually in the US (Click on their site for great info).  It tends to show up on sun exposed areas, like the nose, ears, and chest.  Although it almost always is limited to the skin, basal cell carcinoma can be locally destructive if not treated.

Depending on the type and location of the basal cell carcinoma, different treatment options can be used.  Superficial types may be treated with a cream called imiquimod that is applied 5 times a week for 6 weeks.  Or, a scraping procedure called electrodessication and curettage (ed&c) can be performed in the dermatologist's office.  Larger or infiltrative basal cells can be excised in the office under local anesthesia by the dermatologist.  Very large basal cells, or ones located on the nose, lips, ears, or close to the eyes, where there is not a lot of tissue available, may be removed by the Mohs procedure.  This is a special type of skin cancer surgery where tissue is removed and checked under the microscope while the patient is still in the office.  Once the Mohs surgeon has determined that all the skin cancer has been removed, the area is stitched up.  Mohs surgery has a very high cure rate.  Usually dermatologists who perform this procedure have an additional year of training after residency to become experts in Mohs.  This is the treatment Bruce Jenner had.    

Once someone has had one basal cell carcinoma, they are 50% more likely to develop a second one.  As this type of skin cancer is directly related to sun exposure, protecting your skin from the sun is a great way to prevent their development.  Proper sunscreen use of a broad spectrum UVA/UVB sunblock is essential.  Clothing, such as hats and shirts, that are specially treated to have a UPF (ultraviolet protection factor) of 50+ can really help protect your skin from the sun.  

Any bump that doesn't go away, bleeds, itches, crusts, or grows needs to be seen by a dermatologist to make sure it's not a skin cancer ASAP.  Remember, one in five Americans will develop skin cancer in the course of a lifetime.  "Keep up" with of your skin - it's the only one you have!

There's a new tightener in town

The latest weapon in the war against aging and gravity?  Ultherapy!  This nonsurgical, effective treatment uses ultrasound to stimulate collagen, resulting in a tighter and lifted lower face and neck.  When used on the upper face, it can lift the brow and open the eyes.

Ultherapy is an FDA-cleared device that delivers energy to a set depth below the surface of the skin, without injuring the surface of the skin.  This energy then stimulates collagen production, resulting in a toned, tighter appearance.  The treatment takes between 60-90 minutes, depending on which areas are treated.  There is very minimal to no downtime.  Occasional side effects include temporary swelling and bruising.  Patients can return to their normal activities after the treatment.  Results take about three months, and improvement may continue for up to six months.  Ideal candidates are those in their 30's and older with some skin laxity.

Ultimately, the best results often result from synergistic treatments: a good skin care regimen, botox, fillers, lasers, and tightening technologies all work together to keep skin looking radiant and youthful.

MelaFind

Now dermatologists have another tool to add to their toolbox in the fight against melanoma.  MelaFind is an FDA-approved device that scans suspicious moles and analyzes them.

How does it work?
First, the dermatologist performs an skin exam and selects suspicious-appearing moles.  The skin is then cleansed with alcohol.  A painless, hand-held device scans the moles and compares the pattern of the mole to thousands in its database.  A reading is then generated of "high disorganization" or "low disorganization."  Highly disorganized moles are more suspicious for melanoma and warrant a biopsy.
   
Melanoma is a serious type of skin cancer that can be deadly, however, if caught early, is 100% curable.  With regular skin exams, new technology, and sun protection, it's easier than to protect your precious skin.

Shingles: ain't just on the roof

"I feel like something bit me on the lower back."  "I've got this burning, tingling rash."  "There are little blisters on my arm."

What do these people have in common?  All have herpes zoster, aka, shingles.  It's a more common condition than you may think: 1 in 3 people in the United States will develop shingles in their lifetime.  It can affect any sex or age group (including children), although it is more common after age 60. 

Despite its name, herpes zoster is not caused by the herpes virus.  It's caused by the varicella virus, which is the same virus that causes chickenpox.  Once an individual has been infected with the chickenpox virus, it remains inactive (dormant) in our nerves forever.  For reasons not entirely understood, the virus will activate, travel along the nerve, and erupt in the skin that connected to that specific nerve.  This is why shingles only shows up in a portion of the skin, and not everywhere, like chickenpox does. 

Although anyone can develop shingles, those with a weakened immune system due to cancer, pregnancy, illness, and certain immunosuppressive medications are at higher risk.  Shingles usually starts as a tingling or burning sensation in the skin.  A few days later, a red rash with grouped clear, small blisters will appear.  The rash may feel painful or itchy. 

Antiviral treatment is available from your physician, which helps to reduce the length of time and severity of the shingles.  They should be started early in the course to be most effective.  A dreaded complication of shingles is post-herpetic neuralgia, which is persistent nerve pain in the area of shingles.  The antiviral treatment may help prevent this condition.  Shingles that involves the face, eyes, or ears requires emergent treatment to avoid complications.     

A vaccine, called Zostavax, is available for patients age 60 and older.  It may prevent the development of shingles.

How to treat a sunburn

Pretty much everyone knows that getting a sunburn is a bad idea.  Aside from being uncomfortable or downright painful, a sunburn accelerates the aging process and increases the risk of developing skin cancer, including melanoma.  But occasionally, even to the most cautious people, it can happen.  So what can be done to treat it?

Seek the shade
First and foremost, get out of the sun and into a cool, shady place to prevent any more damage at the first signs of a sunburn.  Unfortunately, the redness and discomfort may not show up until a few hours after the burn. 

Cool down
Cool showers, cool compresses, and slathering on moisturizing creams can help.  Avoid scrubbing the skin.  Eucerin calming cream can often feel soothing.  The moisturizer can be kept in the refrigerator for added benefit.  Taking ibuprofen or aspirin by mouth helps alleviate inflammation and pain.  Remember, kids should never be given aspirin. 

Hydrate
Drink lots of water to re-hydrate.  Headache and dizziness can be a sign of dehydration.  Children can dehydrate easily, so if they seem ill or develop fever, be sure to seek medical attention.  Rarely, IV hydration may be needed.

Relieve the itch
Sunburned skin often feels itchy and tight.  An over the counter hydrocortisone cream can offer some relief.  If it doesn't do enough, a dermatologist can prescribe a stronger cream, or occasionally, oral steroids.  Loose clothing will prevent further irritation of the skin from friction. 

Hands off!
If it's a bad sunburn, blisters may develop.  Avoid picking or peeling blisters or skin, as this can lead to infection.  If many blisters or fever are present, see a physician pronto.

Avoid it
The best way to treat a sunburn is to avoid it in the first place.  Limit time in the sun, wear sun protective clothing (shirts and hats), and slather on the sunscreen every two hours (more often if swimming or sweating).  Remember, we only have one skin: protect it!

Sweat stains, anyone?

It's hotter than all Hades outside: 90 degrees out!  How many of us have ruined shirts because of excessive sweating under arms?  Does your outfit choice depend on which shirt is going to show the stains least?

When antiperspirants and topical products don't do enough to curb the sweating, it's time to visit the dermatologist to discuss Botox.  Yes, the line smoothing treatment is FDA-approved to treat axillary hyperhidrosis, or excessive underarm sweating.  Botox works by blocking the release of a chemical called acetylcholine from the nerve, which is involved in sweating.  It is also used off-label (not FDA-approved) to treat sweating of the hands and feet.     

The treatment is simple and very well tolerated: numbing cream is applied to the underarms, and the the Botox is injected with a very tiny needle.  It takes a week for results, which then last about 6 months. 

Raise your arms and cheer- without worrying about sweat spots!

Melt that muffin top

Summer is here.  Bathing suits, pool parties, beach fun, muffin tops- oh, wait, was that not on your summer list?  Even with exercise and a well-balanced, healthy diet, those stubborn stomach bulges can be tough to eliminate.

Thankfully, a non-invasive, non-surgical (no cutting!), no-downtime option is available to battle that waistline.

Liposonix uses high intensity focused ultrasound (HIFU) to target and destroy fat cells. The fat cells are then naturally absorbed by the body over time. A single treatment that takes about an hour is all that is usually needed. This is a great treatment for people who are close to their ideal size and shape, but have stubborn areas on the belly and/or love handles that just won’t improve with diet and exercise. On average, people will lose one inch off the waistline (which typically means one dress or pant size), and is usually seen within 8-12 weeks.

The wonders of silicone

Everyone has heard of silicone breast implants. But few know that silicone is especially effective in the treatment of acne scarring. Medical grade pure silicone (Silikon 1000) is FDA approved to treat retinal detachment in the eye. Dermatologists have successfully used it off-label for years as a permanent cosmetic filler.

The key is in the technique of how the Silikon 1000 is injected. Tiny amounts of Silikon 1000 are injected as microdroplets into skin, and the treatments are spread out over multiple sessions. The droplets induce collagen to be synthesized around them, which fills in the scar and results in smoother skin.

When injected this way, the treatment is very safe, and can produce beautiful, natural results. However, every filler has risks, and since silicone is permanent, it's especially important to have a board certified dermatologist with cosmetic experience perform the injections.

We all scream for sunscreen

You've heard it before and you'll hear it again: wear sunscreen!  But what sunscreen is best?

Sunscreens should be broad spectrum, meaning they block both UVA and UVB rays.  UVA rays cause the signs of aging: wrinkles, brown spots, and loss of elasticity (read: loose skin).  They pass through clouds and are unaffected by weather.  UVA rays also cause skin cancer.  UVB rays cause sunburns, and vary with the time of day and season.  The SPF rating on sunscreen means the level of protection against UVB rays only.

Sunscreens consist of two classes of ingredients: chemical blockers and physical blockers.  Chemical sunscreens need to be applied 30 minutes before sun exposure so that they can be absorbed into the skin.  Physical blockers, such as zinc oxide and titanium dioxide, sit on the surface of the skin and work immediately.

So which is better?  Many sunscreens contain a combination of the two classes.  Some people are irritated by chemical sunscreens, in which case a physical block would be better.  Physical sunscreens also tend to be more sweat resistant (which is handy for exercising), although any sunscreen should be reapplied after swimming or sweating excessively.

I'm so happy about the the newest line carried at Horwitz Dermatology: EltaMD.  The UV Pure is a broad-spectrum (blocks UVA and UVB), chemical-free sunscreen.  It's great for kids and adults whose sensitive skin can be irritated by chemicals.  It's also fragrance-free, paraben-free, and noncomedogenic (as are all the EltaMD susncreens).  For those who prefer a spray sunscreen, the UV Spray is a broad-spectrum sunscreen.  The spray works really well for hair-bearing areas, such as mens' chests and backs.  It also is nice for kids (although the spray is not chemical-free).  A few caveats with spray sunscreens, however.  I recommend applying a lotion sunscreen first and then using the spray to reapply.  Also, it's important, with both spray and cream, to use enough of the product for full coverage.  For acne or rosacea prone patients, the UV Clear sunscreen contains 5% niacinamide, which helps calm redness.  Finally, the UV lip balm is an antioxidant containing sunscreen that helps protect an often neglected area of our bodies. 

In south Florida, protecting your skin is important all year round.  Choosing sunscreens that are effective and cosmetically elegant make that possible.

Brown spots, be gone

It's a common problem many women (and men) battle everyday - brown spots/areas on the face. These brown patches usually show up on the forehead, cheeks, upper lip, and chin area. Women tend to be affected more often than men. No one knows exactly what causes it, but we do know that there are certain factors that seem to trigger the increase in pigmentation. Sun exposure and estrogen are the two biggies. Birth control pills, hormone replacement therapy, and pregnancy (in which case it is called chloasma, or the mask of pregnancy) rev up melanocytes to produce more melanin, which is responsible for pigment in the skin.

Melasma is a difficult condition to treat. There is no cure and no set treatment. A combination of topical medications and procedures are used to improve it, but results need to be maintained. The single most important factor is sun exposure. People with melasma MUST protect their skin from the sun. Sun avoidance, suncreen, sun protective clothing: the whole nine yards.

The most commonly prescribed topical treatment is the lightening cream hydroquinone. This should be used under a dermatologist's supervision.   Although there are reports of a possible association of cancer, nothing has been confirmed, and it is still considered the gold standard and first line treatment.  A very rare complication of this cream is a condition called ochronosis, which results in darkening of the skin. Fortunately, this is not common. Retinoid cream helps to lighten dark spots as well.  A prescription cream called Triluma combines hydroquinone, tretinoin, and a topical steroid cream and is very effective.  

There are many other topical treatments available that do not contain hydroquinone. These are often used as well to treat melasma. These creams contain lightening ingredients such as azaleic acid, kojic acid, licorice, lignin peroxidase, etc. One of my favorite non-hydroquinone containing creams is Lytera.  It contains niacinamide, licorice extract, and retinol.   

In addition to topical treatments, light chemical peels can be performed in the doctor's office. However, care must be taken to avoid hyperpigmentation (darkening of areas). The Fraxel Dual Re:Store has been shown to be very effective for brown spots on the face and can improve melasma.

Just as exercise and diet are used to help maintain a healthy weight, strict sun protection and various dermatologist-prescribed treatments can help maintain skin.

Shopping and Botox and points, oh my!

A few posts back, I wrote about Allergan's free Brilliant Distinctions program, which is a rewards program.  Points are issued for Botox, Juvederm, and Latisse, which then translates into rebates.  In addition, Allergan has introduced the Brilliant Distinctions mall. 

Log into the Brilliant Distinctions home page and access the mall, which has hundreds of stores that many of us online shop at on regular basis: DSW, Piperlime, Tory Burch, Target, etc.  Shop as you normally would, and for each dollar amount spent, you will earn points that can then be redeemed for rebates on Botox, Juvederm, and Latisse!

Additionally, points can be issued in the office when SkinMedica products are purchased.  I routinely recommend many SkinMedica products anyway (TNS Essential Serum, Lytera, foaming face wash, sunscreen, etc.), so earning points is an added bonus.

Saavy shopping takes on a whole new meaning!

Zap that fat

Even though temps in Miami have temporarily dropped, they will soon be up to the sweltering norm.  This means less clothes and more skin.  And even though many of you have been exercising and eating a well-balanced, healthy diet, those stubborn stomach bulges can be tough to eliminate.

Thankfully, a non-invasive, non-surgical (no cutting!), no-downtime option is available to battle that muffin top.

Liposonix uses high intensity focused ultrasound (HIFU) to target and destroy fat cells.  The fat cells are then naturally absorbed by the body over time.  A single treatment that takes about an hour is all that is usually needed.  This is a great treatment for people who are close to their ideal size and shape, but have stubborn areas on the belly and/or love handles that just won’t improve with diet and exercise.  On average, people will lose one inch off the waistline (which typically means one dress or pant size), and is usually seen within 8-12 weeks.

To gel or not to gel?

Recently, an article was published in the New York Post about the risks of gel manicures, which are all the rage these days.  Women are loving gels, which last longer than a regular manicure, with less of a risk of chipping, etc.  However, the gel requires ultraviolet light (UV) to set and dry the polish.  So what's the problem with that?

The issue is that ultraviolet light causes skin cancer.  Whether from natural sunlight, tanning beds, or lights used in the gel manicure, any exposure to UV light increases the risk of developing basal cell carcinoma, squamous cell carcinoma, and/or, even more worrisome: melanoma.  With repeated exposures, the risk increases.

Wearing sunscreen helps reduce the risk, but the best way is really to avoid the exposure in the first place.  So while there may be more chipping with a plain 'ol manicure, a chip is better than a cancer.

Oh, zit

Sometimes it happens- a huge pimple shows up. Usually at the most inconvenient times- right before a big, important event filled with a million people.

So what to do? The best and quickest solution is to see a derm, stat. She/he can inject the pimple with cortisone, which reduces inflammation and shrinks it down quickly. If there is infection present, the area may need to be opened and drained and/or antibiotics may be given.

At home, warm compresses and salicylic acid creams can help. Applying a mild hydrocortisone cream helps, too- but generally, hydrocortisone causes acne, so should not be used regularly on the face.

Most importantly, no picking or squeezing. This can cause infection and scarring. Best to leave the zit zapping to the skin experts: the dermatologist.

Can Botox help depression?

We all know the improvement that Botox and Dysport can make in wrinkles caused by movement in the face: frown lines, crow's feet, forehead wrinkles, gummy smile, wrinkles around the mouth, dimpled chin, neck bands, and more. But did you know that studies have shown improvement in people's mood following the treatment?

A study performed in Switzerland took 30 people with a history of depression that did not improve previously with medication. 15 people had their frown lines injected with Botox (onabotulinumtoxin) and 15 were injected with a placebo (saline). There was a significant improvement in mood in the group treated with Botox.

Much has been written about the mind-body connection: that our physical state can affect our moods/emotions and vice versa. Although more research needs to be conducted, Botox may prove to be a great treatment for depression in the future.
