3D Digital Skin Analysis

O’Donoghue Dermatology, one of the area’s leading medical and cosmetic dermatology practices, is pleased to announce the addition of 3D digital skin analysis assisted by the Reveal® Imager to their newly renovated 1952 Field Road, Sarasota office.

The Reveal® Imager uses Canfield Scientific’s exclusive RBX technology to uncover skin damage undetectable to the naked eye. This state-of-the-art technology uses cross-polarized filters to produce a digital image that shows the unique color signatures of red and brown skin components below the skin surface.

Red areas can represent a variety of conditions including acne, inflammation, rosacea, and spider veins. In contrast, brown areas which are caused by an excess in melanin, and are often associated with sun damage, represent lesions such as hyperpigmentation, freckles, lentigines or melasma on or below the skin surface.

“In just a few minutes, the Reveal® Imager produces a report that allows us to analyze hyperpigmentation, photo damage, vascular disorders, rosacea, acne, texture and wrinkles so that we can develop a skin care regimen that specifically targets the patient’s needs” said Dr. O’Donoghue.

The benefits of vitamin D

For my Sarasota dermatology 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.

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.

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.

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.

Acne Scarring

Did you know that we no longer have to rely on aggressive chemical peals and dermabrasion to treat acne scarring?

With the new lasers available today, we can treat acne scarring in as little as 15 minutes, with no anesthesia and with minimal healing.

If you're one of the millions of people that are plagued by acne scarring, contact O'Donoghue Dermatology to see if you are a candidate for this revolutionary procedure.

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.
