Sunscreen is an essential part of sun safety, but there's a lot of misinformation out there. Here are some common sunscreen myths debunked:
Myth 1: Sunscreen is only necessary on sunny days.
False! Up to 80% of UV rays can penetrate clouds, meaning your skin is still at risk of damage even on overcast days. Sun reflects off surfaces like water, sand, and snow, increasing exposure. Wear sunscreen every day, regardless of the weather.
Myth 2: Sunscreen is only for fair skin tones.
False! Everyone needs sunscreen, regardless of skin tone. While fair skin burns more easily, all skin tones are susceptible to sun damage, including premature aging and dark spots.
Myth 3: Sunscreen causes cancer.
False. There's no evidence of this, but there's plenty showing UV rays from the sun and tanning beds do cause cancer. Some sunscreens were recalled for benzene contamination, but this doesn't mean all sunscreens are unsafe. Choose a reputable brand and check the ingredients if concerned.
Myth 4: A high SPF means I don't need to reapply.
False. Sunscreen needs reapplication every 2-3 hours, and more often if sweating or swimming. No sunscreen is completely waterproof. Look for "water-resistant" labeled products and follow the reapplication instructions.
Myth 5: Sunscreen blocks vitamin D production.
Partially true. Sunscreen can reduce vitamin D production, but most people get enough vitamin D from diet and incidental sun exposure. If concerned about vitamin D levels, talk to your doctor about supplements.
