7 Sunscreen Misconceptions
Misconception #7. SPF is all that matters.
Fact: The SPF number on sunscreens only reflects the product’s screening ability for UVB rays. Make sure your sunscreen covers both UVB and UVA rays. While UVB rays cause sunburn; UVA rays cause more long-term effects such as premature skin aging.
Misconception #6. Apply sunscreen just before you go out.
Fact: Sunscreen should be applied 20-30 minutes BEFORE you go out. It doesn’t work immediately.
Misconception #5. I should replace my sunscreen every summer.
Fact: Unless indicated by an expiration date, the FDA requires that all sunscreens be stable and at their original strength for at least three years.
Misconception #4. The best Sunscreen is all I need to protect myself from the sun.
Fact: The best sunscreen still allows rays to pass through. Wear protective clothing. Dark is better than light. A big hat is better than a cap. If you have to be bare, seek shade when appropriate, remembering that the sun’s rays are strongest between 10 a.m. and 4 p.m.
Misconception #3. Mosquito repellant and sunscreen can be applied the same time.
Fact: If you also want to use mosquito repellent, first apply the sunscreen - and 20 minutes later, apply the repellent. Studies show combining them increase DEET penetration into your skin.
Misconception #2. I only need to wear sunscreen when it’s sunny.
Fact: Even on cloudy days, when it does not feel hot, or when you’re under trees, the sun still emits damaging UV rays. By the same token, wear it year round, not just in summer. Even driving in your car in the winter sun can tan your left cheek through the glass window.
Misconception #1. I always wear the best sunscreen so I’m immune to skin damage.
Fact: Never say never. Check your birthday suit on your birthday. If you notice anything changing, growing, or bleeding on your skin, see a dermatologist. Skin cancer is very treatable when caught early.
Have you heard The Sunscreen Song? It was an adaptation from a commencement speech. It’s funny, it’s true, it’s uplifting, it’s down-to-earth, and the older I grow, the more I appreciate it. Click here for Baz Luhrman’s Sunscreen Song
