Sunscreen is essential for protecting your skin against skin cancer, sunburn, and premature aging, but it must be applied correctly to be effective. Board-certified dermatologists offer these five tips to ensure you get the protection you need:
- Choose a sunscreen with SPF 30 or higher, water resistance, and broad-spectrum coverage (UVA and UVB rays). Tinted sunscreens with iron oxide provide additional protection against dark spots and visible light.
- Apply sunscreen before going outdoors to allow approximately 15 minutes for absorption and protection. Waiting until you are in the sun leaves your skin vulnerable to burning.
- Use enough sunscreen, typically about 1 ounce, to cover your entire body. Thoroughly rub it into your skin, covering all exposed areas.
- Apply sunscreen to all skin not covered by clothing, including your neck, face, ears, feet, legs, and scalp if hair is thinning. Use a spray sunscreen or seek assistance for hard-to-reach areas like your back.
- Reapply sunscreen every two hours, especially after swimming or sweating, to maintain protection. Sunburn often occurs due to inadequate reapplication or insufficient sunscreen use.
Remember, your skin is exposed to UV rays every time you go outside, regardless of the weather or season. If you suspect sun damage, consult a board-certified dermatologist for examination and personalized recommendations. To find a dermatologist near you, visit Find a Dermatologist.
