Skin Safe, Sun Safe

Let’s get it right from the start, anyone, any skin type, any skin color is at risk for skin cancer. Indeed, nobody is safe from skin cancer. Skin type and skin color do not fully protect an individual from skin cancer. Skin safe, sun safe practices do protect and do help in skin cancer prevention.

Lynne Kurashima, Hawaii Licensed Aesthetician, says, “It’s a misconception that darker skin types think they’re fully protected.” This common myth continues today because of the belief that darker skin types have natural melanin protection from solar radiation exposure.

While it is true that darker skin types are at a lower risk for developing skin cancer and have some natural melanin protection from solar radiation, this false sense of security leads to a lack of education and sun protection practices that are important for all skin types. In a study of Hispanics and Blacks, solar radiation exposure seemed to play a large role in the development of melanoma in both of these groups1. Education on sun protection and skin cancer risk should be offered and an annual skin cancer screening should be performed by a dermatologist for all people.

The American Academy of Dermatology’s How to Perform a Self Examination

• Examine your body front and back in the mirror, then right and left sides with arms raised.
• Bend elbows and look carefully at forearms, upper underarms and palms.
• Look at the backs of your legs and feet, the spaces between your toes and on the sole.
• Examine the backs of your neck and scalp with a hand mirror. Part hair for a closer look.
• Finally, check your back and buttocks with a hand mirror

It is estimated by the World Health Organization that as many as 60,000 people a year worldwide will die from too much sun, predominantly in the form of malignant skin cancer. Forty-eight thousand deaths are attributed to malignant melanoma and 12,000 from other forms of skin cancer. Of these cancers, 90 percent are caused from ultraviolet light from the sun2. In the United States alone, more than 1 million new cases of skin cancer will be diagnosed3. One out of five Americans will develop some form of skin cancer during their lifetime4. You can improve your clients’ chances by taking the time to learn about skin cancer, especially for skin of color.
According to the American Cancer Society, cancer “occurs when cells in a part of the body begin to grow out of control.” The name of the cancer is attributed to the part of the body where the cells began to grow out of control. For example, an out of control growth of cells in the skin is named skin cancer. Just as an out of control growth of cells in the lungs is named lung cancer. Or as an out of control growth of cells in the breast is called breast cancer. These out of control cells behave differently and respond to different treatments. These out of control cells have the ability to break away from the initial part of the body where they started to grow and spread through the blood or lymph system to other parts of the body, this is known as metastasis, the spread of cancer. Should the cells begin to grow out of control after an initial diagnosis and successful treatment of cancer leaving the body free of cancer, this regrowth is labeled as a recurrence.
There are two primary categories of skin cancer, nonmelanoma and melanoma. Nonmelanoma is the most common skin cancer and is usually identified as basal cell or squamous cell. One percent of nonmelanoma skin cancer is of other types. If detected early, both basal and squamous cell carcinomas have a better than 95 percent five-year rate.
Basal cell carcinoma begins at the lowest layer of the epidermis. Three of four skin cancers are basal cell carcinoma. Often developing on sun exposed areas of the skin, it is slow growing. It does not tend to spread to distant body parts, although it can reoccur in the same or in different parts of the body. Basal cell carcinoma often appears flat and firm. It can be pale, pink, red or translucent in color. It may be blue, brown or black and may ooze or crust. It is often a shiny, waxy area that may bleed after injury. It may have one or more irregular blood vessels and may be depressed in the center.
Squamous cell carcinoma begins in the upper layer of the epidermis. Two out of 10 skin cancers are squamous cell carcinoma. This type of skin cancer can begin with a scar or skin ulcer. It can occur in the genital area. If occurring in the genital area, it is often linked to a virus causing genital warts. It invades the fatty tissues and is more likely to spread to lymph nodes or distant body parts. Squamous cell carcinoma often appears as a growing lump, a rough surface, a flat, reddish patch. Bowen Disease is a squamous cell carcinoma in situ, a benign tumor that is the earliest form of squamous cell carcinoma. It appears reddish and with great exposure to the sun is a risk factor.
Basal and squamous cell carcinomas can be detected with a skin cancer screening and monthly self checks (see sidebar 2 on page 56.). Warning signs of nonmelanoma skin cancer include new growths or a spot that grows and does not heal within three months. Prevention of nonmelanoma skin cancer can be practiced with sun safety (see sidebar). The causes of nonmelanoma skin cancer include ultraviolet radiation exposure variables, virus infection, chemicals, genetics, long term or severe skin problems, skin disease, a weakened immune system or prior diagnosis of skin cancer. Human papillomavirus (HPV) is a virus infection that is a known cause of nonmelanoma skin cancer. As are certain chemicals like arsenic and industrial tar, coal, and certain oils which are known to cause nonmelanoma skin cancer. Some individuals are sensitive to sunlight chromosomes and are therefore genetically at risk for nonmelanoma skin cancer as are individuals with long term or severe skin problems who have compromised skin. One example is xeroderma pigmentosum which affects the skin’s ability to repair sun damage of the skin.
Melanoma begins in the melanocyte cells which create the brown pigment, melanin, which helps differentiate skin color. It is the second most common cancer in women aged 20-29.

Heavy exposure and severe sunburns in childhood are believed to be the greatest environmental contribution to melanoma7. Ultraviolet radiation alone is not the only cause of melanoma. A large mole count, especially the presence of an atypical mole, dysplastic nevi, is a risk factor. Awareness of the ABCDE’s of melanoma moles is important in your practice and for your clients’ knowledge. Skin type (Fitzpatrick I and II) and family history are also risk factors. As are personal history of skin cancer, like basal cell carcinoma and squamous cell carcinoma which place an individual in the higher risk factor group for melanoma development. A weakened immune system as a result of chemotherapy, diseases like lymphoma or HIV and excessive sun exposure are also considerations for greater awareness of melanoma and the risk factors.
In general, outdoor exposure time, for example, an avid gardener who works outside will be more susceptive to ultraviolet radiation damage as opposed to an accountant working inside a dark office building with little or no ultraviolet radiation exposure. Tanning bed use is another factor as is geographic location, for example living in West Palm Beach, Florida versus Chicago, Illinois. Lastly, a history of skin cancer makes an individual more prone to being diagnosed again.
It’s time to take responsibility for skin health. Be skin safe, be sun safe. You can help your clients practice skin safety by performing a skin analysis that includes a skin cancer awareness and mole check. Observe the appearance and changes in size, shape, color, and texture. Be aware of bleeding, oozing, and scaling. Have your client visit a dermatologist that you have partnered with for a skin cancer screening. Andrea DeSimone, New York Licensed Aesthetician, says, “it’s wonderful when aestheticians take the extra time to keep track of their client’s skin so the client feels more taken care of… the client knows you’re on top of it for them and they return to you for this level of attention and care.”
If in doubt, a dermatologist can perform a biopsy. There are a number of biopsy methods available: shave, punch, incisional and excisional, and lymph node. A shave biopsy involves shaving off a layer of skin. A punch biopsy uses a cookie cutter type of tool to remove a sample of the skin. An incisional or excisional biopsy is a surgical removal of skin. Incisional only removes a portion of the skin and an excisional removes all of the skin in question. A lymph node biopsy is used to determine if the cancer has spread and either a fine needle aspiration (FNA) is used with a syringe like tool for small tissue removal or the lymph node is removed in its entirety. From the biopsy it can be determined if the concern is indeed skin cancer or not. If staging is pertinent, it is often determined at this time as well. Staging is a classification of the severity of the cancer, ranging from 0 to IV, IV being most serious. Basal cell carcinoma is rarely staged unless it is very large for it does not tend to spread. Squamous cell may spread so this type of staging classification is often used.
Benign skin tumors are rarely cancer and do not tend to become cancer. However, they are an indication that the skin is damaged and regular checks are especially important of damaged skin. Actinic keratosis also known as solar keratosis is a type of benign skin tumor. It is a precancerous problem that indicates too much sun exposure. It appears as small, rough spots, pink, red, or flesh colored. In most cases it appears on the face, ears, back of hands, and arms. It is slow growing and the primary symptom is a patch or patches on the skin that can turn into cancer and should be carefully checked for changes.
As the skin care professional, you can educate your clients on how to protect themselves and the risk factors and considerations associated with skin cancer. Dr. Marcia Glenn, Founder and Director of Odyssey MediSpa, Marina del Rey, CA, encourages her patients to examine their skin monthly and pay particular attention to their moles. She suggests women take the time to do both their skin self exam and their breast self exam at the same time.
As the skin care professional, build your awareness and build your retail sales by offering sun protection products that include both a UVA and UVB protecting ingredient with a minimum Sun Protection Factor (SPF) 15. Ensure ease of sun smart practices by having each client leave your business with a sun protection product. Gift yourself and your clients with the power of this knowledge. Learn more and build your business as a skin cancer aware skin care professional. Practice skin safety, practice sun safety!

The American Academy of Dermatology’s Be Sun Smart Program

Sun exposure is the most preventable risk factor for skin cancer. You can have fun in the sun and Be Sun SmartSM. Here’s how to do it:
• Generously apply sunscreen to all exposed skin using a Sun Protection Factor (SPF) of at least 15 that provides broad-spectrum protection from both ultraviolet A (UVA) and ultraviolet B (UVB) rays. Re-apply every two hours, even on cloudy days, and after swimming or sweating.
• Wear protective clothing, such as a long-sleeved shirt, pants, a wide-brimmed hat and sunglasses,
where possible.
• Seek shade when appropriate, remembering that the sun’s rays are strongest between 10 a.m. and 4 p.m.
• Use extra caution near water, snow, and sand as they reflect the damaging rays of the sun which can increase your chance of sunburn.
• Protect children from sun exposure by applying sunscreen.
• Get vitamin D safely through a healthy diet that includes vitamin supplements. Don’t seek the sun.
• Avoid tanning beds. Ultraviolet light from the sun and tanning beds causes skin cancer and wrinkling. If you want to look like you’ve been in the sun, consider using a sunless self-tanning product, but continue to use sunscreen with it.
• Check your birthday suit on your birthday. If you notice anything changing, growing, or bleeding on your skin, see a dermatologist. Skin cancer is very treatable when caught early.

    Upselling and add-ons – a challenging subject to talk about even in the best of times. But here we are in the middle of an economic crisis, so you must be asking yourself how we could possibly consider this a reasonable topic when you are just happy you are able to sustain your clientele. Many of you are probably thinking there is no way you would jeopardize that relationship by asking the client to spend more money. All of which are perfectly reasonable thoughts and questions. However, I will ask you to put them in a box briefly, clear your mind, and be open to consideration for just a moment.

    Let me give you an example of an effective suggestion that happens millions of times, everyday, all around the world. You go to your favorite restaurant; you sit down, and look over the menu. Your server comes to the table and takes your order, you tell him what you would like and he confirms your order then says, “Would you like a salad with that tonight, or can I interest you in a glass of wine?” A perfectly harmless question, that was neither painful nor offensive. At worst you say “No, thank you.” At best, he just enhanced your dining experience, increased your bill, and ultimately his tip. Job well done!

    Selling retail is an essential part of a well run spa. This is true not only because the additional revenue is so crucial to a spa's bottom line, but also because prescriptive home care is the necessary second step to the professional care given to a client in the spa. While mastering the retail sale can be difficult from a team or individual perspective, there are methods for making your spa’s retail routine hum.

     

     

    Your Spa's Style

    Oftentimes spas try to sell a bit of everything in an attempt to accommodate everyone. This can be a fatal error. The more fragmented your retail mix the more clients and staff will be confused. There must be a driving force behind your spa philosophy. Are you primarily a spa focused in on medical skin care, contouring services, water therapies, or all organic non-ablative therapies? Before you can determine the best retail mix for your spa, you really need to dig deep and understand your theme, focus, and primary therapeutic offerings. Moreover, remember that if you can’t get the product on them in the treatment room—there is a much smaller chance that the client will be taking the product home with them for further use when not at the spa. Integrating the treatment experience with the retail experience is crucial. When determining your retail mix, be cognizant of your client. Do you primarily offer clinical services or is your treatment mix somewhat more “fluffy” or gift-oriented?

    When Sarah Hughes skated off with the gold medal, she pulled off one of the biggest upsets in Olympic history. Her surprisingly simple secret? “I didn’t skate for a gold medal. I went out and had a great time.”

    Athletes say it all the time: “I just went out there and had fun.” And, admittedly, they do look like they’re having a great time.

    Fortunately, fun isn’t the sole province of superstar athletes. It can work for the rest of us in the skin care industry, too. The link between having fun and business success has been proven in countless studies. When we’re having fun on the job, we are more creative and more productive.

    A couple of decades ago, offering cream and sugar for anything other than coffee or tea would have sounded quite ridiculous! But in today’s realm of aesthetics and cosmetics promoting coffee and chocolate to soothe even the jitteriest skin, or offering sugar as a real hair removal solution to an age-old problem is very realistic. And as post treatment, applying a good trans-dermal cream to hydrate and moisturize the skin is simply a great, soothing and natural way to complete your sugaring service.

    Jan Marini - August 2010: A Legend in Aesthetics
    Jan Marinin

     

    Those who know Jan Marini refer to her as a visionary. While Jan might agree in principle, she sees this characterization as both a strength and a weakness. She envies those who are able to savor the moment. Where others view life in snapshots that capture real time, Jan sees broad borderless landscapes and endless possibilities. She does not see a product, she sees a business and in that same instance her mind is flooded with the business plan and all the accompanying details. Even when she is not envisioning empires, she is never satisfied with the status quo.
    Given her background, perhaps this is an understandable if not necessary survival tool. Jan’s mother, Florence, was a single mom of three boys in an era when divorce carried a major stigma. Florence remarried and unexpectedly gave birth to Jan late in life. The family struggled to live a very meager existence. Her father died when she was eight years old and the family was thrust into poverty. Florence worked only menial jobs and food was often scarce. It was no wonder that Jan viewed her world not as it was, but as it might be, and that she softened the bleak reality by envisioning a larger and more optimistic scenario brimming with potential. Because of her early circumstances, Jan is adamant that in order to succeed you must be tenacious, doggedly determined, and completely focused on the ultimate goal.
    Jan describes herself as a product researcher. “Back in the early days I was considered a product ingredient expert. I lectured to medical professionals, skin care professionals, and consumers about how ingredients really performed and what they could realistically expect to provide.” She also did talk radio and T.V., because as she puts it, “consumers love to hear about ingredients and whether their products really work. It is a popular topic that lends itself to talk shows.”
