This aggressive skin cancer is often preventable with consistent sun protection. However, many people remain unsure about which sunscreen to use.
At Dr. Kim Dermatology in Frisco, Texas, board-certified dermatologist Dr. Kimberly Werner Billet offers personalized, science-backed skin care guidance. Her clinical expertise and global perspective help patients make smart sunscreen choices to reduce their melanoma risk.
Why Sunscreen Is Critical for Melanoma Prevention
Melanoma develops when UV radiation damages the DNA in skin cells. Over time, this damage can cause uncontrolled cell growth and cancer. Sunscreen acts as a barrier, lessening the penetration of harmful rays.
Research published in the journal Genes & Diseases reveals that UV exposure contributes to up to 90% of nonmelanoma skin cancers and approximately 65% of melanoma cases.
What to Look for in a Sunscreen
Not all sunscreens are created equal. To defend your skin effectively, your sunscreen should be:
- Broad-Spectrum: This means the product blocks UVA (aging) and UVB (burning) rays.
- SPF 30 or Higher: SPF 30 blocks 97% of UVB rays. Higher SPFs offer only marginally more protection but may be more beneficial if you’re outdoors for long periods.
- Water-Resistant: Especially important if you’re swimming or sweating.
- Mineral-Based: Look for zinc oxide or titanium dioxide. These are less irritating and ideal for sensitive or acne-prone skin.
Tips for Proper Application
Many people don’t use enough sunscreen or reapply it often enough. Follow these steps for a better defense:
- Apply a full ounce (about a shot glass) to your entire body 15 minutes before going out in the sun.
- Reapply every two hours or immediately after swimming or profuse sweating.
- Don’t forget ears, feet, and the back of your neck.
