When the Texas sun is shining — and let’s be honest, that’s most of the year — it’s natural to want to enjoy the outdoors. But protecting your skin should be more than just an afterthought. Even if you’re careful, common myths about sun protection can put your skin — and your health — at risk. Let’s set the record straight on sunscreen, sunburn, and skin cancer, and share the best ways to protect yourself all year long.
Myth #1: You Only Need Sunscreen on Sunny Days
You might think cloudy or cool weather means you can skip sunscreen, but up to 80% of UV rays can still reach your skin on overcast days, according to the Skin Cancer Foundation. Snow, water, and even sand can reflect UV rays and increase your exposure, so sunscreen is essential every day, regardless of the weather or season.
Advice: Make sunscreen part of your daily routine, just like brushing your teeth. Choose a broad-spectrum sunscreen with SPF 30 or higher and apply it to all exposed skin, even on overcast days.
Myth #2: “I have darker skin, so I don’t have to worry about skin cancer.”
No matter your skin tone, you can get sun damage and skin cancer. While people with darker skin are less likely to burn, they’re still at risk for UV damage. In fact, skin cancers in people with darker skin are often diagnosed at later, more dangerous stages.
Advice: Everyone should use sunscreen. If you have a darker complexion, mineral sunscreens with zinc oxide or titanium dioxide may blend better and leave less residue.
Myth #3: Sunscreen Causes Cancer
There’s no evidence that sunscreen ingredients cause cancer. In fact, using sunscreen lowers your risk of developing skin cancer, including melanoma, the deadliest form. The FDA regulates sunscreen ingredients to ensure safety and effectiveness. The National Academies add that “sunscreen use is not linked to higher rates of any type of cancer.”
Advice: Don’t let misinformation scare you away from this vital protection. Mineral-based sunscreens are a good choice if you’re concerned about ingredients; they work by sitting on top of your skin and physically blocking UV rays.
Myth #4: You Only Need to Apply Sunscreen Once
Sunscreen wears off — especially if you’re swimming, sweating, or towel-drying. Even water-resistant formulas lose effectiveness over time.
Advice: Reapply sunscreen every two hours, and immediately after swimming or heavy sweating. Carry a travel-size bottle or stick for easy reapplication throughout the day
Myth #5: “A base tan protects me from sunburn.”
A tan is a sign of skin damage, not protection. According to the American Academy of Dermatology (AAD), a base tan provides the equivalent of about SPF 3, which is far below what your skin needs to prevent UV damage.
Advice: Instead of relying on a tan, apply broad-spectrum sunscreen and cover up when possible.
Myth #6: High SPF Means You’re Fully Protected
SPF 30 blocks about 97% of UVB rays, while SPF 50 blocks 98%. The difference is small, and no sunscreen offers 100% protection. What matters most is applying enough and reapplying often.
Advice: SPF 30 is sufficient for most people if used properly. Higher SPFs are helpful if you have very fair skin, a history of skin cancer, or spend long periods outdoors.
Myth #7: You Don’t Need Sunscreen Indoors or in the Car
UVA rays can penetrate glass, causing premature aging and increasing skin cancer risk, even if you’re inside or driving.
Advice: Apply sunscreen to exposed skin every day, especially if you spend time near windows or on the road.
How to Choose—and Use—Sunscreen the Right Way
- Pick the right product. Choose one that fits your skin type and lifestyle. If you have sensitive skin, mineral-based sunscreens may be a better option. For oily or acne-prone skin, look for “non-comedogenic” on the label. Use at least SPF 30.
- Apply enough. Adults should use about 1 ounce (a shot glass full) to cover their entire body. Don’t forget your ears, the tops of your feet, your scalp (or wear a hat), and your lips (use an SPF lip balm).
- Reapply regularly. Every two hours — and more often if you’re sweating or swimming.
- Don’t rely only on sunscreen. Wear a wide-brimmed hat, sunglasses with UV protection, and seek shade when the sun’s rays are strongest, usually between 10 a.m. and 4 p.m.
- Check expiration dates. Sunscreen loses effectiveness over time.
The Importance of Regular Skin Checks
Sun protection is only part of the story. Skin cancer is the most common cancer in the United States, but when caught early, it’s highly treatable. That’s why regular skin checks are so important.
- Do monthly self-exams. Look for new spots or changes in existing moles. Use the “ABCDE” rule: Asymmetry, Border irregularity, Color variation, Diameter larger than a pencil eraser, and Evolving over time.
- See a dermatologist. If you notice anything unusual or have a family history of skin cancer, talk with your doctor about how often you should have a professional skin check.
The Takeaway
Sun protection isn’t just for beach days, it’s a daily habit that can save your skin and your life. By debunking these common myths, you can make smarter choices and keep your skin healthy for years to come. Don’t forget: sunscreen, shade, protective clothing, and regular skin checks are your best defense against the Texas sun.
If you have questions about skin protection or concerns about a mole or spot, talk to your primary care provider or schedule a visit with a dermatologist at TexasHealth.org/Doctors.
