Tucson's Tan: Desert Sun Hiding Harm for Dark Skin?

By Franklin Everett Shaw

The Arizona sun, a relentless force beating down on Tucson, doesn’t discriminate. But the way our skin reacts to it absolutely does. For those of us with darker skin tones, there’s a dangerous misconception that melanin provides an impenetrable shield. It’s time to shatter that myth and arm ourselves with the knowledge to protect our skin, right here in the heart of the desert.

Melanin does offer some natural protection. It’s true. Think of it as a very, very light sunscreen. But it’s nowhere near enough, especially in Tucson, where the UV index regularly hits extreme levels.

Here’s the stark reality: melanin provides an SPF of roughly 13. That’s it. Compare that to the recommended SPF of 30 or higher, and you see the problem.

Skin cancer does affect people of color. And often, it’s diagnosed later, when it’s more advanced and harder to treat. This is due, in part, to the false belief that we’re immune.

So, what can dark-skinned Tucsonans do to stay safe under the Arizona sun?

First, sunscreen is non-negotiable. Every. Single. Day. Even on cloudy days, UV rays penetrate.

Choose a broad-spectrum sunscreen with an SPF of 30 or higher. Broad-spectrum means it protects against both UVA and UVB rays.
Look for mineral sunscreens containing zinc oxide or titanium dioxide. These are generally considered safer and more effective, especially for sensitive skin.
Apply generously. Most people don’t use enough. Aim for about an ounce (a shot glass full) to cover your entire body.
Reapply every two hours, or more often if you’re sweating or swimming. Set a timer on your phone to remind you.

Second, understand the UV Index. This is a daily forecast of the strength of the sun’s UV rays. You can find it on weather apps or websites.

When the UV index is 3 or higher, take extra precautions, like seeking shade and wearing protective clothing.
The sun is strongest between 10 a.m. and 4 p.m. Try to limit your exposure during these hours.

Third, protective clothing is your friend.

Wear wide-brimmed hats to shield your face, ears, and neck. Baseball caps don’t cut it.
Opt for long sleeves and pants when possible, especially during peak sun hours.
Look for clothing with a UPF (Ultraviolet Protection Factor) rating. This indicates how much UV radiation the fabric blocks.

Fourth, know your skin and check it regularly.

Perform self-exams monthly, looking for any new or changing moles, spots, or lesions.
Pay attention to areas that are often exposed to the sun, like your face, neck, arms, and legs.
Don’t forget to check your scalp, ears, and the soles of your feet.

Fifth, find a dermatologist who understands skin of color. This is crucial. Not all dermatologists are equally experienced in diagnosing and treating skin conditions in darker skin tones.

Look for dermatologists who are board-certified and have experience treating patients with diverse skin types.
Ask about their experience with skin cancer detection and treatment in people of color.
Consider dermatologists who are members of professional organizations like the Skin of Color Society.

Here are a few Tucson dermatologists known for their expertise in skin of color:

Dr. Vivian Bucay at Bucay Center for Dermatology. She is known for her expertise in cosmetic and medical dermatology, with a focus on diverse skin types.
Dr. Sheila Farhang at Avant Dermatology. She is a board-certified dermatologist with a special interest in skin cancer prevention and treatment, as well as cosmetic dermatology for all skin types.
Dr. Emily Tierney at Tierney Dermatology. She offers comprehensive dermatological care, including medical, surgical, and cosmetic dermatology, with a focus on personalized treatment plans.

Don’t be afraid to ask questions and advocate for your health.

Common mistakes and pitfalls:

Believing the melanin myth: This is the biggest and most dangerous mistake.
Using expired sunscreen: Sunscreen loses its effectiveness over time. Check the expiration date.
Not applying enough sunscreen: Most people only apply 25-50% of the recommended amount.
Forgetting to reapply: Sunscreen needs to be reapplied every two hours, or more often if you’re sweating or swimming.
Ignoring suspicious spots: Any new or changing mole, spot, or lesion should be checked by a dermatologist.
Thinking you’re safe in the shade: While shade does offer some protection, UV rays can still reflect off surfaces like sand and water.
Skipping sunscreen on cloudy days: Up to 80% of the sun’s UV rays can penetrate clouds.

Let’s debunk some common myths about sun protection in the Southwest:

Myth: People with dark skin don’t need sunscreen. Fact: Everyone needs sunscreen, regardless of skin color.
Myth: Sunscreen is only necessary when you’re at the beach or pool. Fact: Sunscreen should be worn every day, even when you’re just running errands.
Myth: A base tan protects you from sunburn. Fact: A tan is a sign of skin damage, not protection.
Myth: You can’t get sunburned on a cloudy day. Fact: UV rays can penetrate clouds and cause sunburn.
Myth: All sunscreens are the same. Fact: Different sunscreens offer different levels of protection. Choose a broad-spectrum sunscreen with an SPF of 30 or higher.

Early detection is key. Skin cancer in people of color often presents differently than in lighter skin tones.

Melanoma in darker skin is more likely to occur on the palms of the hands, soles of the feet, and under the nails. This is called acral lentiginous melanoma (ALM).
Basal cell carcinoma and squamous cell carcinoma can appear as pigmented lesions, making them harder to distinguish from moles or other skin conditions.
Any sore that doesn’t heal, or a new or changing growth, should be checked by a dermatologist.

Here’s a step-by-step guide to performing a self-exam:

Stand naked in front of a full-length mirror.
Examine your face, including your nose, lips, mouth, and ears. Use a hand mirror to check the back of your ears and neck.
Inspect your scalp, using a comb to part your hair.
Check your hands, including your palms, fingers, and fingernails.
Examine your torso, front and back.
Check your legs and feet, including your soles, toes, and toenails.
Use a hand mirror to check your buttocks and genitals.

Remember the ABCDEs of melanoma:

Asymmetry: One half of the mole doesn’t match the other half.
Border: The borders of the mole are irregular, notched, or blurred.
Color: The mole has uneven colors, such as black, brown, or tan.
Diameter: The mole is larger than 6 millimeters (about the size of a pencil eraser).
Evolving: The mole is changing in size, shape, or color.

If you notice any of these signs, see a dermatologist immediately.

Living in Tucson means embracing the sun, but it also means respecting its power. By understanding the risks and taking the necessary precautions, we can protect our skin and enjoy the beauty of the desert for years to come. Don’t let misinformation cloud your judgment. Sun safety is for everyone, regardless of skin tone.
