The benefits of vitamin D

Vitamin D has many health benefits. It helps the intestine absorb nutrients like calcium and phosphorus for strong bones and a strong immune system. It prevents rickets, regulates blood pressure, reduces stress, helps fight depression, improves skin health, and countless other benefits.

The benefits of vitamin D can be derived from consuming foods that are naturally rich in vitamin D like salmon and tuna or vitamin D fortified foods like milk and breakfast cereal. The same benefits can be derived from vitamin D supplements and exposure to sunlight.

Exposure to sunlight is the most unreliable source because it depends on factors like the angle of the sun, the pigmentation of your skin and the use of sunscreen products. Exposure to sunlight is also the most dangerous source of vitamin D because it increases your chances of developing skin cancer.

For my patients who are vitamin D deficient, I recommend a diet high in vitamin D rich foods like milk, cheese, and fish. If that is insufficient, I recommend a supplemental oral vitamin spray that is easy to take and readily absorbed. Only as a last resort do I recommend exposure to the harmful rays of the sun.

Choosing the Right SPF Number for You

With so many sunscreen products on the market, choosing the right one for you may be difficult. This information will help you make an informed decision when choosing a sunscreen product.

The first thing to consider is how long you are going to be exposed to the sun. The longer you are in the sun or by a window, the higher the SPF number you should use. It is important to note that, normal glass blocks UVB rays, but allows damaging UVA rays through. Some modern windows block as much as 99.9% of UVA and UVB rays.

Sunscreen products are meant to be applied liberally and reapplied every couple of hours or after sweating or swimming. If you are not planning to use a liberal amount of sunscreen, opt for the higher SPF number than you normally would to ensure that you are getting as much of the protective ingredients as possible on your skin.

If you are going to be swimming or perspiring heavily, choose a sunscreen that is labeled as "water resistant" or "very water resistant" and reapply frequently, especially after toweling off. Keep in mind that no sunscreen can be "water proof", if you have a sunscreen product that is labeled as such; it was purchased before the new FDA labeling requirements went into effect in December of 2012 and it should not be trusted.

SPF stands for Sun Protection Factor and, if the word "factor" reminds you of math class, there is a reason for that. The SPF number is multiplied by the amount of time (in minutes) in which you typically burn when you are not wearing sunscreen to figure out how long it will take to burn with protection. If you typically burn within 20 minutes and you are using SPF 15, 20 min. x 15 SPF = 300 min. or 5 hours.

Very fair skin will typically burns within 20 minutes of sun exposure. Light to medium or olive skin usually burns within about 40 minutes. Medium to tan skin will typically tan before it burns, but it is still at risk of burning after about 60 minutes. Darker skin tans easily and is less likely to burn but, even though the effects of the sun are less evident, the damage is still occurring.

Individuals with very fair skin should use an SPF of 35 or more while exposed to the sun and additional protection like a hat is recommended when exposed to the sun for extended periods of time. Individuals with medium to tan skin should use products with an SPF of 25 or above and darker skin individuals should use an SPF of 20 or greater while out in the sun.

New FDA labeling requirements ensure that products do what they say they do, but the trick is in the proper application of the products. As previously stated, these products are intended to be lathered on. You should use about 1 ounce of sunscreen on your body and using half as much sunscreen does not give you half the protection. Using half as much sunscreen actually gives you the square root of the protection, half the recommended amount of SPF 70 will give you an SPF of about 8.4 not an SPF of 35.

It is not enough to apply a little bit of a high SPF product in the morning and keep going all day.

New FDA Sunscreen Label Requirements

Sunscreens protect our skin from painful sunburns and they reduce our risk of developing skin cancer from long term exposure, but like most products that are designed to make a profit in a competitor filled arena, the claims made by these products evolved into mere hype geared towards gaining market share.

SPF numbers and terms like "broad spectrum" were being used to make all products sound protective but, when put to the test, many of them did not offer the level of protection they promised so the FDA had to step in and force changes that guard consumers from false claims.

The mandated changes took effect in December of 2012 so, if you have a product that was purchased before that time, it is not certain that the packaging reflects the content. These new label requirements will help you make an informed decision:

Sun Protection Factor

Sun Protection Factor or "SPF" refers to the product's ability to keep your skin from getting red. It tells you how long you have before you start to burn, but the redness is just an indication of a sunburn or sun poisoning, the SPF in and of itself does not protect you from developing skin cancer.

UVA and UVB Blockage

The sun emits two types of rays, UVA and UVB, and we need to protect our skin from both types of radiation because both of them can cause skin cancer.

Broad Spectrum

Broad Spectrum means that the product blocks both UVA and UVB rays and therefore protects against skin cancer. Prior to the 2012 labeling changes, many sunscreens claimed to be "broad spectrum" even though they contained very little of UVA or UVB protection. Products that use the term "broad spectrum" now must prove that they offer high levels of both types of protection.
Waterproof, Sweatproof or Water Resistant

No sunscreen is truly waterproof or sweatproof so they are no longer allowed to make these claims. Sunscreens may only claim to be "water resistant" and they must provide information regarding when to reapply the product (between 40 and 80 minutes).

Sunscreen Products

Sunscreen products come in a variety of forms including lotions, sprays, wipes, shampoos and it is now commonly found in makeup. The new labeling requirements only apply to products that are specifically intended to protect against the sun, nothing else. This means that a sunscreen lotion or a sunscreen wipe is regulated; shampoos or other multi-function cosmetics are not so, do not rely on these products as your primary source of protection.

O’Donoghue Dermatology Doubles in Size

Leading Sarasota dermatology practice announces the completion of a major renovation and expansion to their Field Road office.

SARASOTA, Florida (June 25, 2013) – Driven by continued growth and their commitment to offering the most advanced treatment options available, O'Donoghue Dermatology, one of the area's top medical and cosmetic dermatology practices, is pleased to announce the completion of a major renovation and expansion to their 1952 Field Road office which nearly doubles its square footage.

The expansion includes a separate waiting room where patients undergoing Mohs surgery for the treatment of skin cancer can relax between stages, a phototherapy room for the treatment of chronic skin disorders like psoriasis, vitiligo and eczema, and an aesthetician suite for cosmetic procedures including chemical peels, microdermabrasion, and dermaplaning.
The expansion also includes 2 new patient rooms, an additional on-premise sterilization laboratory, a physician assistant office, and a larger reception area which is equipped with a projection screen and can comfortably accommodate 25 patients.

"The newly renovated reception area will allow us to offer regular dermatology lectures and free educational seminars on topics such as the prevention and treatment of diseases of the skin, the latest advancements in skin care products and technology, and how to take care of our skin in order to age gracefully" said Dr. O'Donoghue.

Dr. J. Morgan O'Donoghue is a graduate of the prestigious Georgetown University School of Medicine in Washington D.C. He completed his internship in Internal Medicine at Tulane University in New Orleans, LA and went on to do his residency in Dermatology and Cutaneous Surgery at Washington Hospital Center in Washington, D.C. Dr. O'Donoghue has had numerous scientific articles published in national peer-reviewed dermatology journals and he is currently completing his first book on the topic of skin cancer prevention.

Dr. O'Donoghue is certified by the American Board of Dermatology, he is a fellow of the American Academy of Dermatology, and a board member and fellow of the Florida Society of Dermatologic Surgeons. He is a proud member of the American Medical Association and the Sarasota County Medical Association, and he is a staff member at Sarasota Memorial Hospital.

GentleLASE Laser Hair Reduction

If you or a loved one have unsightly or unwanted hair on any part of your body, or if you have experimented with other methods of hair removal or reduction that were tedious, painful or not as long-lasting as you had hoped, the GentleLASE Laser may just be the solution you have been waiting for.

The GentleLASE laser emits an invisible beam of light that interacts with the pigment or melanin in the hair follicle destroying it at the root while preserving the surrounding skin. Because the laser energy interacts with the melanin in the hair root, the treatment is not well suited for patients with red, blonde or gray hair, and patients should not use any other form of epilation for at least 6 weeks prior to the treatment in order to ensure that the follicle is present.

The laser also interacts with the pigment in your skin so tanning should be avoided for 6 weeks before and after the treatment and patients with very dark skin are not good candidates for the procedure because the active melanin in their skin could cause them to have a reaction to the treatment. Before the area is treated, excess hair will be shaved off in order to reduce the risk of burning from singed surface hair and so the laser energy is focused on the root of the follicle.

This effective, long-lasting treatment for the removal of unwanted hair is gentle, safe and fast so it is ideal for larger areas where hair removal would be too painful with other forms of epilation like waxing and electrolysis. To give you an idea of the speed of this treatment, an entire back can be treated in as little as 20 minutes.

Laser hair removal can be safely performed on any part of the body, with the exception of eyebrows and eyelashes because of the proximity to the eyes, and protective eyewear must be worn by everyone in the treatment room whenever the laser is in use.

O'Donoghue Dermatology brings in a GentleLASE Laser every 6 weeks. This allows our patients to schedule their treatments on a 6 weeks cycle so the hair has sufficient time grow and we can treat as much hair as possible on each visit. Most patients will require 6 to 8 treatments for truly lasting results and you can expect to come in for a touch up once or twice a year. O'Donoghue Dermatology offers a discount to patients who book 4 or more treatments at one time.

If you have any questions about the GentleLASE laser or to find out if you are a good candidate for this revolutionary procedure, feel free to contact O'Donoghue Dermatology at (941) 926-7546.

Nail Fungus?

Onychomycosis or nail fungus can occur on fingernails or toenails, but it is far more common on toenails because, like other fungi, onychomycosis thrives in dark, moist environments like the environment that results from feet perspiring in shoes and socks all day.

Nail fungus can grow underneath or on top of the nail, and it forces the nail up off of the nail bed making the nail thick, crumbly and discolored. The discoloration can range from yellow to brown and it can easily spread from the infected nail to the other nails on the foot.

There are a number of over the counter treatments that can be applied directly to the affected area and do not have the side effects of oral medications that are on the market, but it is always best to have a dermatologist examine the condition to ensure that it is not some other type of nail disease mimicking onychomycosis.

If you are tired of hiding thick, crumbly and discolored toenails, contact O'Donoghue Dermatology today to schedule a consultation.

Winter Itch

Winter itch is a type of eczema or very dry skin which is exacerbated by the lower humidity of the winter months.

This condition can be alleviated by applying moisturizer to wet, freshly showered skin and avoiding long, hot showers which can deplete skin of its natural oils. Diets rich in vitamins A, C, E, flaxseed, canola and fresh vegetable will enhance the skin's ability to retain moisture, and running a humidifier in the bedroom while you sleep is also helpful.

If your winter itch proves too much for these home remedies, contact O'Donoghue Dermatology so that we can determine the best treatment for you.

Sebaceous Cysts

A sebaceous cyst is a bump that develops under the skin, typically in the neck, face or trunk area.

They are often referred to as wens, keratin cysts, epidermal cysts or epidermoid cysts and they usually come out of hair follicles, but they can be caused by trauma to the skin.

The bump is formed by a closed sack filled with an oily or cheese-like matter and it is usually painless, but it can become inflamed and tender. If a small cyst becomes inflamed, your dermatologist can inject it with an anti-inflammatory medication to reduce the swelling or just surgically remove the cyst.

Most cysts are benign, but it is important to differentiate them from other malignant bumps that may look like cysts. In some cases, your dermatologist may determine that a biopsy is necessary to rule out potentially malignant conditions.

If you are concerned about a bump on your skin, contact O'Donoghue Dermatology so that we can determine if it is a benign cyst or something worthy of concern.

Many patients are concerned when they develop a bump that looks like a cyst.

This is usually a sebaceous cyst that is a closed sac found under the skin, usually on the trunk, neck, or face. They are filled with a oily or cheese-like matter and usually are painless.

In some cases, however, cysts can get inflamed and become tender to the touch. They are also called epidermal cysts, wens, keratin cysts, or epidermoid cysts. Most often, sebaceous cysts come out of hair follicles or can form as a result of trauma to the skin. Usually they are benign, but they must be differentiated from other potentially malignant bumps that can mimic cysts.

In some cases, the dermatologist will perform a biopsy to rule out certain conditions. If a small cyst becomes inflamed, a dermatologist can inject it with an anti-inflammatory medication to reduce swelling or just remove it entirely with surgery.

Are you at risk for melanoma?

Melanoma only affects 4 percent of those diagnosed with skin cancer, but it accounts for 79 percent of all skin cancer related deaths.

Anyone who has overexposure to the sun, regardless of skin color, has a higher risk for melanoma.

Individuals with blond or red hair, and fair complexion have the highest risk for melanoma. Also if you experienced excessive sun exposure during your childhood and teen years or have a family history of melanoma, you should have a skin cancer-related checkup.

The American Cancer Society recommends a checkup every three years for people between 20 and 40 years of age, and every year for anyone 40 and older.
