Choosing the Right Sunscreen for Skin Cancer Prevention

Protecting your skin from the sun is one of the most important steps you can take to reduce your risk of skin cancer. But with so many sunscreen options on store shelves, how do you know which one is right for you?

Here’s a simple guide from your CCNW care team to help you choose a sunscreen that offers the protection you need.

1. Look for Broad-Spectrum Protection

Not all sunscreens protect against both types of harmful UV rays:

• UVA rays age the skin and contribute to wrinkles.
• UVB rays burn the skin and are the main cause of skin cancer.

Broad-spectrum sunscreens protect against both. Make sure the label clearly says “Broad Spectrum.”

2. Choose SPF 30 or Higher

SPF, or Sun Protection Factor, measures how well the sunscreen protects against UVB rays. Dermatologists recommend:

• SPF 30 or higher for daily use.
• Higher SPFs (like 50+) may be a good choice for people with very fair skin, a history of skin cancer, or prolonged outdoor activity.

Remember: No sunscreen blocks 100% of UV rays, so combine sunscreen with other protective measures like shade and clothing.

3. Pick the Formula That Works for You

Sunscreen comes in many forms—lotions, sprays, sticks, and gels. The “best” sunscreen is the one you will actually use. Consider:

• Lotions for full-body coverage.
• Sticks for sensitive areas like around the eyes.
• Sprays for easy application on arms, legs, or backs (but be sure to rub it in for full coverage).

4. Check for Water Resistance

If you’re swimming or sweating, choose a sunscreen labeled “water-resistant for 40 or 80 minutes.” No sunscreen is fully waterproof, so be sure to reapply regularly, especially after swimming or towel drying.

5. Mineral vs. Chemical Sunscreens: What’s the Difference?

• Mineral (Physical) Sunscreens: Contain zinc oxide or titanium dioxide. These sit on top of the skin and reflect UV rays. Great for sensitive skin and young children.
• Chemical Sunscreens: Contain ingredients like avobenzone or oxybenzone. These absorb UV rays before they damage the skin. Often lighter in texture but can irritate sensitive skin for some people.

Both types are effective—choose the one that feels best on your skin.

6. Bonus Tip: Watch the Expiration Date

Sunscreen loses its effectiveness over time. Check the expiration date, and don’t use old or separated sunscreen.

Choosing the right sunscreen is a key part of protecting yourself against skin cancer, including melanoma—the most serious type. And remember: sunscreen works best when combined with other sun-safe practices:

• Seek shade
• Wear hats and sunglasses
• Avoid tanning beds
• Get annual skin checks

If you have a personal or family history of skin cancer—or if you’re undergoing cancer treatment that makes your skin more sensitive to the sun—talk with your care team for tailored recommendations.
